Chapter 2
Introduction
3
Before using the Handyprobe HP3 first read chapter 1 about safety.
Many technicians investigate electrical signals. Though the measurement may not be electrical, the physical variable is often converted to an electrical signal, with a special transducer. Common transducers are accelerometers, pressure probes, current clamps and temperature probes. The advantages of converting the physical parameters to electrical signals are large, since many instruments for examining electrical signals are available.
The Handyprobe HP3 is a single channel, 10 bits measuring instrument with differential input with high input range. The Handyprobe HP3 is available in several models with different maximum sampling rates and different maximum streaming rates.
Maximum sampling rate Maximum streaming rate
HP3-100 100 MSa/s
10 MSa/s
HP3-20 20 MSa/s
2 MSa/s
HP3-5 5 MSa/s 500 kSa/s
Table 3.1: Maximum sampling rate
The Handyprobe HP3 is available with two memory configurations, these are:
Memory Standard model Option XM
HP3-100 16 kSa 1 MSa
HP3-20 16 kSa 1 MSa
HP3-5 16 kSa 1 MSa
Table 3.2: Maximum record lengths per channel
With the accompanying software the Handyprobe HP3 can be used as an oscilloscope, a spectrum analyzer, a true RMS voltmeter or a transient recorder. All instruments measure by sampling the input signals, digitizing the values, process them, save them and display them.
3.1 Differential input
Most oscilloscopes are equipped with standard, single ended inputs, which are referenced to ground. This means that one side of the input is always connected to ground and the other side to the point of interest in the circuit under test.
Introduction
5
Figure 3.1: Single ended input
Therefore the voltage that is measured with an oscilloscope with standard, single ended inputs is always measured between that specific point and ground.
When the voltage is not referenced to ground, connecting a standard single ended oscilloscope input to the two points would create a short circuit between one of the points and ground, possibly damaging the circuit and the oscilloscope.
A safe way would be to measure the voltage at one of the two points, in reference to ground and at the other point, in reference to ground and then calculate the voltage difference between the two points. On most oscilloscopes this can be done by connecting one of the channels to one point and another channel to the other point and then use the math function CH1 – CH2 in the oscilloscope to display the actual voltage difference.
There are some disadvantages to this method:
· a short circuit to ground can be created when an input is wrongly connected · to measure one signal, two channels are occupied · by using two channels, the measurement error is increased, the errors made
on each channel will be combined, resulting in a larger total measurement error · The Common Mode Rejection Ratio (CMRR) of this method is relatively low. If both points have a relative high voltage, but the voltage difference between the two points is small, the voltage difference can only be measured in a high input range, resulting in a low resolution
A much better way is to use an oscilloscope with a differential input.
6
Chapter 3
Figure 3.2: Differential input
A differential input is not referenced to ground, but both sides of the input are “floating”. It is therefore possible to connect one side of the input to one point in the circuit and the other side of the input to the other point in the circuit and measure the voltage difference directly.
Advantages of a differential input:
· No risk of creating a short circuit to ground
· Only one channel is required to measure the signal
· More accurate measurements, since only one channel introduces a measurement error
· The CMRR of a differential input is high. If both points have a relative high voltage, but the voltage difference between the two points is small, the voltage difference can be measured in a low input range, resulting in a high resolution
3.1.1 3.2
Differential test lead
The Handyprobe HP3 comes with a special differential test lead This test lead is specially designed to ensure a good CMRR and to be immune for noise from the surrounding environment.
The special differential test lead provided with the Handyprobe HP3 is heat resistant and oil resistant.
Sampling
When sampling the input signal, samples are taken at fixed intervals. At these intervals, the size of the input signal is converted to a number. The accuracy of this number depends on the resolution of the instrument. The higher the resolution, the smaller the voltage steps in which the input range of the instrument is divided. The acquired numbers can be used for various purposes, e.g. to create a graph.
Introduction

Figure 3.3: Sampling
The sine wave in figure 3.3 is sampled at the dot positions. By connecting the adjacent samples, the original signal can be reconstructed from the samples. You can see the result in figure 3.4.
Figure 3.4: “connecting” the samples
3.3 Sampling rate
The rate at which the samples are taken is called the sampling rate, the number of samples per second. A higher sampling rate corresponds to a shorter interval between the samples. As is visible in figure 3.5, with a higher sampling rate, the original signal can be reconstructed much better from the measured samples.
8
Chapter 3
Figure 3.5: The effect of the sampling rate
3.3.1
The sampling rate must be higher than 2 times the highest frequency in the input signal. This is called the Nyquist frequency. Theoretically it is possible to reconstruct the input signal with more than 2 samples per period. In practice, 10 to 20 samples per period are recommended to be able to examine the signal thoroughly.
Aliasing
When sampling an analog signal with a certain sampling rate, signals appear in the output with frequencies equal to the sum and difference of the signal frequency and multiples of the sampling rate. For example, when the sampling rate is 1000 Sa/s and the signal frequency is 1250 Hz, the following signal frequencies will be present in the output data:
Multiple of sampling rate …
-1000 0
1000 2000
…
1250 Hz signal
-1000 + 1250 = 250 0 + 1250 = 1250
1000 + 1250 = 2250 2000 + 1250 = 3250
-1250 Hz signal
-1000 – 1250 = -2250 0 – 1250 = -1250
1000 – 1250 = -250 2000 – 1250 = 750
Table 3.3: Aliasing
As stated before, when sampling a signal, only frequencies lower than half the sampling rate can be reconstructed. In this case the sampling rate is 1000 Sa/s, so we can we only observe signals with a frequency ranging from 0 to 500 Hz. This means that from the resulting frequencies in the table, we can only see the 250 Hz signal in the sampled data. This signal is called an alias of the original signal.
If the sampling rate is lower than twice the frequency of the input signal, aliasing will occur. The following illustration shows what happens.
Introduction
9
Figure 3.6: Aliasing
In figure 3.6, the green input signal (top) is a triangular signal with a frequency of 1.25 kHz. The signal is sampled with a rate of 1 kSa/s. The corresponding sampling interval is 1/1000Hz = 1ms. The positions at which the signal is sampled are depicted with the blue dots. The red dotted signal (bottom) is the result of the reconstruction. The period time of this triangular signal appears to be 4 ms, which corresponds to an apparent frequency (alias) of 250 Hz (1.25 kHz – 1 kHz).
To avoid aliasing, always start measuring at the highest sampling rate and lower the sampling rate if required.
3.4 Digitizing
When digitizing the samples, the voltage at each sample time is converted to a number. This is done by comparing the voltage with a number of levels. The resulting number is the number corresponding to the level that is closest to the voltage. The number of levels is determined by the resolution, according to the following relation: LevelCount = 2Resolution. The higher the resolution, the more levels are available and the more accurate the input signal can be reconstructed. In figure 3.7, the same signal is digitized, using two different amounts of levels: 16 (4-bit) and 64 (6-bit).
10 Chapter 3
Figure 3.7: The effect of the resolution
The Handyprobe HP3 measures at 10 bit resolution (210=1024 levels). The smallest detectable voltage step depends on the input range. This voltage can be calculated as:
V oltageStep = F ullInputRange/LevelCount
For example, the 200 mV range ranges from -200 mV to +200 mV, therefore the full range is 400 mV. This results in a smallest detectable voltage step of 0.400 V / 1024 = 0.3906 mV.
3.5 Signal coupling
The Handyprobe HP3 has two different settings for the signal coupling: AC and DC. In the setting DC, the signal is directly coupled to the input circuit. All signal components available in the input signal will arrive at the input circuit and will be measured. In the setting AC, a capacitor will be placed between the input connector and the input circuit. This capacitor will block all DC components of the input signal and let all AC components pass through. This can be used to remove a large DC component of the input signal, to be able to measure a small AC component at high resolution.
When measuring DC signals, make sure to set the signal coupling of the input to DC.

Before connecting the Handyprobe HP3 to the computer, the drivers need to be installed.
4.1
4.1.1 4.1.2
Introduction
To operate a Handyprobe HP3, a driver is required to interface between the measurement software and the instrument. This driver takes care of the low level communication between the computer and the instrument, through USB. When the driver is not installed, or an old, no longer compatible version of the driver is installed, the software will not be able to operate the Handyprobe HP3 properly or even detect it at all.
The installation of the USB driver is done in a few steps. Firstly, the driver has to be pre-installed by the driver setup program. This makes sure that all required files are located where Windows can find them. When the instrument is plugged in, Windows will detect new hardware and install the required drivers.
Where to find the driver setup
The driver setup program and measurement software can be found in the download section on TiePie engineering’s website. It is recommended to install the latest version of the software and USB driver from the website. This will guarantee the latest features are included.
Executing the installation utility
To start the driver installation, execute the downloaded driver setup program. The driver install utility can be used for a first time installation of a driver on a system and also to update an existing driver.
The screen shots in this description may differ from the ones displayed on your computer, depending on the Windows version.
Driver installation 13
Figure 4.1: Driver install: step 1 When drivers were already installed, the install utility will remove them before installing the new driver. To remove the old driver successfully, it is essential that the Handyprobe HP3 is disconnected from the computer prior to starting the driver install utility. Clicking “Install” will remove existing drivers and install the new driver. A remove entry for the new driver is added to the software applet in the Windows control panel.

Drivers have to be installed before the Handyprobe HP3 is connected to the computer for the first time. See chapter 4 for more information.
5.1 Power the instrument
The Handyprobe HP3 is powered by the USB, no external power supply is required. Only connect the Handyprobe HP3 to a bus powered USB port, otherwise it may not get enough power to operate properly.
5.2 Connect the instrument to the computer
After the new driver has been pre-installed (see chapter 4), the Handyprobe HP3 can be connected to the computer. When the Handyprobe HP3 is connected to a USB port of the computer, Windows will detect new hardware.
Depending on the Windows version, a notification can be shown that new hardware is found and that drivers will be installed. Once ready, Windows will report that the driver is installed.
When the driver is installed, the measurement software can be installed and the Handyprobe HP3 can be used.
5.3 Plug into a different USB port
When the Handyprobe HP3 is plugged into a different USB port, some Windows versions will treat the Handyprobe HP3 as different hardware and will install the drivers again for that port. This is controlled by Microsoft Windows and is not caused by TiePie engineering.

The accuracy of a channel is defined as a percentage of the Full Scale range. The Full Scale range runs from -range to range and is effectively 2 * range. When the input range is set to 4 V, the Full Scale range is -4 V to 4 V = 8 V. Additionally a number of Least Significant Bits is incorporated. The acuracy is determined in the highest resolution.
When the accuracy is specified as ±0.3% of the Full Scale range ± 1 LSB, and the input range is 4 V, the maximum deviation the measured value can have is ±0.3% of 8 V = ±24 mV. ±1 LSB equals 8 V / 1024 (= number of LSB at 10 bit) = ± 7.813 mV. Therefore the measured value will be between 31.813 mV lower and 31.813 mV higher than the actual value. When e.g. applying a 3.75 V signal and measuring it in the 4 V range, the measured value will be between 3.781813 V and 3.718188 V.
