Product Overview

To Use the Probe

Connect PLA3204 to the Oscilloscope
Connect the Type-C connector of the PLA3204 probe to the front-panel digital signal input terminal of the oscilloscope, as shown in the figure below. Each MHO/DHO5000 oscilloscope can connect up to four PLA3204 probes.
- CAUTION
  Before disconnecting the logic probe from the oscilloscope, press the buckle of the connector and then pull out the connector, as shown in the figure below. Pulling or dragging the cable without releasing the buckle may damage the terminator.
- NOTE
  - After PLA3204 is connected to the oscilloscope’s digital channels, the channel indicator light is on. Group indicator lights I, II, III, and IV indicate that the logic probe is connected to the 1st, 2nd, 3rd, and 4th daughter cards respectively. When connected
  - to MHO/DHO5000, it is displayed as I. Probe indicator lights A, B, C, and D indicate that the logic probe is connected to the 1st, 2nd, 3rd, and 4th digital input channel of the oscilloscope respectively.

Connect PLA3204 to Signal under Test.
You can connect any number (≤4) of signals under test to each PLA3204 probe as required. Note that the amplitude of the input signal cannot exceed the maximum working voltage range of the probe. To cater to different applications, the following three methods are provided to connect the PLA3204 to the signal under test.
1. Method 1: connect the PLA3204 to the double row pin header on the DUT, as shown in the figure below.
2. Method 2: connect the signals under test to the leads separately. You can easily identify the corresponding channel of each signal by the color marker band on each lead.
  - TIP
    The crosstalk or ground bounce during use may be caused by the fact that the channels share a single ground lead. It is recommended to add a ground lead to the signal lead for each channel and twist them together. The ground lead should be as close as possible to the corresponding signal lead.
3. Method 3: on the basis of Method 2, connect a grabber clip to the lead and use the metal hook of the clip to connect the signal under test, as shown in the figure below.
Set the Probe.
Press the front-panel LA key of the oscilloscope to enter the LA setting menu.
In this menu, you can set the threshold level, waveform size, and channel label as well as calibrate the probe. For details, refer to your oscilloscope user guide.
CAUTION
When the probe is connected to the oscilloscope for the first time or when the changes of the ambient temperature are above 5℃, it is recommended to use the ProbeCalibration function in the LA setting menu to perform zero calibration for the probe. Do not connect signals to the PLA3204 input terminals in calibration.

Function Inspection.
Follow the instructions to connect the PLA3204 probe to the oscilloscope and set the probe. Connect the logic signals to the probe. After finishing the operations above, the signal under test will be displayed on the corresponding digital channel on the oscilloscope screen. If no signal is displayed, adjust the oscilloscope to select proper general settings (e.g. trigger mode and time base). If the problem still persists, please check the electric connection and parameter settings again or use other probes (such as analog probes) to check the signal state of the test point.
