Page 9: Introduction
The Handyprobe HP3 is a single channel, 10 bits measuring instrument with dif- ferential input with high input range. The Handyprobe HP3 is available in sev- eral models with different maximum sampling frequencies and different maximum... - Page 10 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.

Page 11: Differential Test Lead
3.1.1 Differential test lead The Handyprobe HP3 comes with a special differential test lead. This test lead is specially designed to ensure a good CMRR. The special heat resistant differential test lead provided with the Handyprobe HP3 is designed to be immune for noise from the surrounding environment. -
Page 12: Sample Frequency
Figure 3.3: Sampling The sine wave in figure 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 Sample frequency The rate at which the samples are taken is called the sampling frequency, the number of samples per second. -
Page 13: Aliasing
Figure 3.5: The effect of the sampling frequency The sampling frequency 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. -

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 frequency of 1 kHz. The corresponding sampling interval is 1/1000Hz = 1ms. The positions at which the signal is sampled are depicted with the blue dots. -
Page 15: Signal Coupling
1024 = 0.3906 mV. 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. - Page 16 Chapter 3...

Page 17: Driver Installation
Introduction To operate a Handyprobe HP3, a driver is required to interface between the mea- surement software and the instrument. This driver takes care of the low level communication between the computer and the instrument, through USB. When... - Page 18 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.
