4.10 Autoset for Waveform Display UTD1000L Series is designed with autoset function that can automatically adjust the vertical
scale, scan timebase and trigger mode based on the input signal until the optimal waveform can be obtained. To apply the autoset function, the tested signal should have a frequency at 20Hz and duty cycle1;
Under AUTOSET mode, the coupling mode of the channel is closely connected to DC autoset; When DC autset is set to off, all signals in the channel is AC-coupled. If DC autoset is on, the channel will choose the current setting as coupling mode, when the current setting is DC coupling, the signal will be DC-coupled and vice versa.
For example:

UTD1000L User Manual

1. Input 1kHz, 2Vpp sine signal into two channels, set coupling mode for both channels to DC, press Shift+UTILITY and then F3 to set DC autoset to off. If AUTOSET is applied, the coupling mode is switched to AC mode. 2. Input 1kHz, 2Vpp sine signal into two channels, then set AC coupling for one channel and DC mode to the other. When AUTOSET is applied, the coupling modes for both channels keep unchanged.
4.11 Full Autoset for Input Signal UTD1000L can offer creative auto function to capture input signal. With this function

4.25 Autoset for Signals with DC Offset
UTD1000L Series is designed with powerful autoset function that makes it possible to perform fast and accurate measurement in DCcoupled mode for signals with any DC component. Position parameter on upper right display of screen: This parameter stands for position readout for the channel reference marker that moves from horizontal central line, if it is positive value, it indicates the channel marker is above the horizontal central line and the negative one is for the marker below the horizontal central line. To work out the final DC offset, first move the waveform to the center of the screen, then multiply the Position value by current amplitude range readout, that is final DC offset result you want. For example: Connect UTD1000CL channel with 70mVpp AC sine signal mixed with 1.1V DC offset, set the channel to DC coupling, then perform AUTO function, the waveform in Figure 4-24A will show on the screen. On the display, Position readout -53.63div indicates the channel reference marker moves 53.63div downward from the horizontal central line. The current amplitude range is 20mV/div, so DC offset readout: 20mV/div×53.63div =1.0726V
Vpp readout: 72mV means the AC peak-to-peak value of the signal You can also directly read out the DC level through AVG value. AVG value: 1.0726V, which stands for the signal DC level. Through all parameters mentioned above, the signal can be understood very easily. Note: For UTD1000DL models, CH1 and CH2 are both set to DC coupling when inputting the signal above, then perform the AUTO function, after that, also move the waveform to the center of the display(See Figure4-24B ), and then calculate DC offset with use of Position readout and current amplitude range value.

Figure 4-23 UTD1000L Setup for Signals with DC Offset As for traditional oscilloscope, it needs hard work to complete the task, for it has to set the coupling to AC mode first to measure out the AC parameters, and then reset the coupling to

Press s/ns button slow down or speed up the scan rate from 10ns or 5ns/div50s/div. Notes: For 25MHz-bandwidth models: 10ns/div50s/div; 50MHz-bandwidth Models: 5ns/div50s/div.

6.3.2 Moving Waveforms Horizontally
Press Left and Right buttons to adjust pretrigger depth. The trigger location is usually set at horizontal center on the screen. With the adjustment, you can observe 6div pretrigger and delay data. Through moving the waveform horizontally, more trigger information can be viewed, which let users know more about pretrigger situation. For instance, by observing and analyzing pretrigger data of glitches occurring in circuit start-up, you can trace down the cause to the glitches. Press HORIZONTAL button to switch on horizontal menu, refer to the following figure:

UTD1000L User Manual

6.3.3 Zooming in/out Waveforms Switch on horizontal menu and press F1 button to zoom in one segment of the wavefom. The timebase for expanded window shouldn’t be lower than that of main window. Note: Timebase faster than 100ns cannot enter into expanded window.

Figure 6-5 Screen Display under Window Zoom Under window zoom function, there are two separate display zones as indicated in the figure above. The upper part is for the original waveform. Press OK button and then use Left and Right buttons to select the waveform to be expanded on the left or right, or enlarge or narrow down the selected zone with s/ns button. The lower display is for the expanded waveform corresponding to the selected original zone. One point worth mentioning is that compared with the main timebase, the expanded timebase has improved the resolution for the waveform display (See Figure 6-5). Since the displayed waveform corresponds to the selected zone of upper part, using s/ns button to narrow down the selected zone can enable the expanded waveform to have better timebase, namely, a higher waveform amplification factor in a horizontal direction.
6.3.4 Adjusting Trigger Hold-Off Switch on horizontal menu, use Right and Left buttons to adjust hold-off time
(100ns-1.5s). It can be applied to observe complex waveforms (eg: burst). Hold-off time is to adjust data acquisition period of the oscilloscope to stay in a integral multiple related to the period of complex waveform so that the Oscilloscope and complex waveform can synchronize.
For example, apply tested combined signals into CH1. Press HORIZONTAL to turn on horizontal menu, then press Right and Left buttons to adjust the hold-Off time until displayed waveform become stable. See Figure 6-6:

UTD1000L User Manual

Figure 6-6 Trigger Hold-Off Note: 1. The trigger hold-off time can be adjusted only when horizontal menu displays.
2. Generally hold-off time is a little smaller than “Big Period’, for instance for RS232 communication signal waveform, hold-off time should be a little larger than start edge time of each frame in order to easily observe the waveform.
6.4 Setting Trigger System Trigger system determines when the Oscilloscope starts to acquire data and display
waveforms. Once the trigger is properly set, the Oscilloscope can transform unstable signal into meaningful waveform. When the acquisition starts, the Oscilloscope continuously acquires enough data to fill the pretrigger portion that is displayed to the left of trigger point. Then the trigger occurs, the Oscilloscope will continue to acquire enough data to fill the posttrigger waveform to the right of trigger point. TRIGGER button is designed to set up the Oscilloscope trigger functions. TRIGGER: Trigger menu button Trigger Level: to set up signal voltage that corresponds to the trigger point.

Term Explanation

1. Trigger Source: Input channel is used as the trigger source

Input Channel: Input channel (CHI) is the most commonly used trigger source. For the

channel selected as the trigger source, it should be switched on before it works normally.

2. Trigger Mode: decide what the oscilloscope will do when no trigger event occurs. Three

trigger modes are offered: Auto, Normal and Single.

Auto: The system automatically acquires data even there is no signal input and therefore

displays scan reference line on the screen; when the trigger occurs, it converted into trigger

scanning and synchronizes with the signal on its own.

Note: The Oscilloscope will go into SCAN mode if waveform scan rate is set at 50ms/div or

lower timebase.

Normal: Under this mode, the Oscilloscope acquires the waveform only after the trigger

conditions are met. It stops to acquire and keeps waiting if no signal is input. Once the trigger

occurs, the scan starts.

Single: You just need to press RUN button if under single mode, then the Oscilloscope waits

to trigger. It begins to acquire and display all acquired waveforms once single-shot trigger

signal is detected, after that, it stops.

3. Trigger Coupling: To decide to pass which kind of components through the trigger circuits.

The types include: DC, AC and Hf Reject.

DC: passes through all components of the signal AC: blocks DC component and attenuate signals at 10Hz HF Reject: attenuates high frequency component at 80kHz

4. Pretrigger/Delay Trigger: Capture data before /after the trigger event.The trigger is usually

located at the horizontal center point on the screen, for example, you can observe 6div

pretriger and delay information, adjusting the waveform horizontally can let you view on more

pretrigger information. Pretrigger can indicate what the waveform is like before the trigger

event. So this function can make it easy, for instance, to find out the cause of glitches in start

moment of circuits through observing and analyzing pretrigger data.

6.5 Setting Acquisition Mode

Press ACQUIRE button to access acquisition mode, see the following table:

UTD1000L User Manual

Note: 1. Use normal mode when you observe single-shot signal. 2. Please select Peak mode if you want to observe signal envelope and also to avoid any
mix-up 3. Use AVG mode if random noise in the signal is required to lower down. The Oscilloscope
steps in multiples of two, please select from 2512 in AVG times 4. Model UTD1000DL can be able to offer fast acquisition function. Term Explanation Normal Mode: The Oscilloscope samples the signals at equal time interval to create the waveform on the display. Peak Detect: Under this mode, the Oscilloscope uses Max. and Min. values detected in each sampling interval to form waveform on the display. It is suitable to capture and display narrow pulse which may probably be neglected if using Normal mode. However the noise under Peak Detect sounds louder. AVG Mode: The Oscilloscope captures certain numbers of waveforms and calculates their average values that will be used to form waveforms on the display. This mode can reduce random noise. Fast Acquisition: it only acquires points for Min. memory depth required for display, which can shorten the hold-off time between each acquisition and realize superb capture rate. It can significantly increase the possibility to find out rarely seen issue.

Term Explanation: Display Format: VECTOR Display fills out all blanks between neighboring points, DOT Display just shows sample points. Update Rate: The times that the oscilloscope updates the waveforms per second. it reflect how fast the Oscilloscope could allow you to observe signal dynamic change. Y-T Mode: In this mode, Y axis represents voltage and X axis for the time. Slow Scan Mode: When the timebase is set at 50ms/div or lower, the Oscilloscope will enter into slow scan mode. This mode is applied to observe low-frequency signal. It is recommended that channel coupling is set to DC.

Harmonic component and distortion in the measurement system. Characterize noises in DC source Analyze the virbration

FFT Operation Tips

Signals with DC components or bias may cause error or deviation to FFT waveform

components. In order to reduce DC component, you can set coupling to AC mode. And you can

set ACQUIRE type to AVG to lower down random noise or mixed overlapped frequency

component in repetitive or single pulse event.

Select FFT Window

Suppose YT waveforms repeats constantly and the Oscilloscope then performs FFT on limited

length record. When the period numers are integer, YT waveform at the start and finish points

share same amplitude values and will not cause any interruption to the waveform. If it is

non-integral, the start and finish amplitude are different, and high-frequency transient

interruption will happen at joint points, which is called leakage in frequency domain. To avoid

the leakage, FFT mode will multiply original waveform with one window function to force the

start and finish values all go to 0. Refer to following windows for details:

Chapter 7 Troubleshooting

7.1 The Oscilloscope cannot power on: The battery may run out. Try to power on the Oscilloscope again with use of the power adaptor. If the instrument still doesn’t work, please contact UNI-T for the service.

7.2 The Oscilloscope turns off a few seconds later after powered on:
The battery may run out. Check if the low battery indicator appears on the screen. If it does, please recharge it.

7.3 Measuring voltage amplitude is 10 times larger or smaller than exact value: Make sure channel attenuation factor is consistent with probe factor on the applied probe.

7.4 No waveform displays after acquiring signals:
1. Make sure the probe is properly connected to the connection wire. 2. Make sure the connection wire is correctly attached to BNC (channel connector) 3. Make sure the probe is properly connected to the tested object. 4. Make sure there are signals generated from the tested object (you can connect the channel
that can produce signals to the suspected channel and verify the cause) 5. Restart the acquisition

7.5 The waveform does not display steadily:
1. Check if trigger source that has been set up in trigger menu is the same with actual input channel
2. Check trigger type: Edge type is generally selected for common signals, use video trigger type for video signals. Onlywhen proper trigger type has been set up can the waveform display steady.
3. Try to change Coupling to HF Reject to filter out the high-frequency inteference noise in the signal.

7.6. There is no display after pressing down RUN/STOP button: 1. Check if Trigger Mode in trigger menu is Normal or Single and trigger level has gone beyond
waveform ranges. If they are, set trigger level to the middle or set trigger Mode to AUTO 2. Or you can press AUTO to automatically finish the setup mentioned above.

7.7 The display slows down after having applied AVG mode for a while: 1. If AVG number go above 32times, it is normal for the oscilloscopes to display at a relatively
low rate. 2. Reduce AVG number

7.8 The waveform display has a stair-stepping shape:
1. It is normal situation, it may be caused by lower horizontal timebase, increasing the timebase can improve the horizontal resolution and the display
2. If display type is VECTOR, links between sample points could probably result in stair-stepping shape. Change display type to Dots can solve the problem.

Appendix B Maintenance 1. General Service
Do not store or place the Oscilloscope in places that may get its LCD exposed to direct sunshine for a long time. Do not let spray agent, liquid and solvent stick onto the Oscilloscope or probe so as to avoid any damage to the Oscilloscope or probe
Cleaning Check the Oscilloscope and its probe as actual operation requires. Clean the Oscilloscope surface as follows:
1. Clean dust on the Oscilloscope and probe surface with soft cloth. Avoid any scratch to LCD transparent protective layer.
2. Clean with soft cloth damped with water or mild agent, no water drop is allowed to occur. Do not use any corrosives or abrasives. Disconnect the power supply before cleaning.
Warning: To avoid any short circuit or even personal injury resulted from residual water, please make sure the Oscilloscope is totally dry before powering it on

2. Storing the Oscilloscope To store the Oscilloscope for a long term, you need to charge the batteries before storing it. 3. Charging Batteries

UTD1000L User Manual

The battery may not be fully charged during the delivery, it must take four hours to fully

charge the battery. The battery can work for 8hours after full charge.

When powered by the battery, the Oscilloscope indicates battery working status on the

upper part of screen.battery indicators may include:

, , , , . And

icon means there is only five minutes left before the Oscilloscope powers off. Please

connect the power adaptor to the Oscilloscope if you want to charge the battery and use the

Oscillosocpe at the same time

Caution:

To avoid over-heating when charging the battery, environment temperature shouldn’t

exceed allowable rated value(0+40).

Note: There is no danger involved even the Oscilloscope has been connected to the charger
for a long time, for instance, during the whole weekend, for the Oscilloscope can automatically switch into very slow charging status. Replacing Lithium Batttery Pack
The battery pack doesn’t need the replacement under general circumstances. If necessary, please have the battery pack replaced by qualified personnel and use new battery with the same specifications.
