  • Page 8: Environmental Considerations

    This section provides information about the environmental impact of the Handyscope HS3. Handyscope HS3 end-of-life handling Production of the Handyscope HS3 required the extraction and use of natural resources. The equipment may contain substances that could be harmful to the environment or human health if improperly handled at the Handyscope HS3’s end of life.

  • Page 9: Introduction

    The Handyscope HS3 is a portable two channel measuring in- strument with Arbitrary Waveform Generator. The Handyscope HS3 is available in several models with different maximum sam- pling frequencies: 5 MS/s, 10 MS/s, 25 MS/s, 50 MS/s or 100 MS/s.

  • Page 10: Sampling

    Sampling When sampling the input signal, samples are taken at fixed inter- vals. 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.

  • Page 11: Sample Frequency

    Sample frequency The rate at which the samples are taken is called the sampling frequency, the number of samples per second. A higher sampling frequency corresponds to a shorter interval between the samples. As is visible in figure 3.3, with a higher sampling frequency, the original signal can be reconstructed much better from the measured samples.

    3.5, the same signal is digitized, using two different amounts of levels: 16 (4-bit) and 64 (6-bit). Figure 3.5: The effect of the resolution The Handyscope HS3 measures at e.g. 12 bit resolution (2 =4096 levels). The smallest detectable voltage step depends on the input...

  • Page 14: Signal Coupling

    DC. Probe compensation The Handyscope HS3 is shipped with a probe for each input chan- nel. These are 1x/10x selectable passive probes. This means that the input signal is passed through directly or 10 times attenuated.
  • Page 15 is called the low frequency compensation. Each time a probe is used on an other channel or an other oscilloscope, the probe must be adjusted. Therefore the probe is equiped with a setscrew, with which the parallel capacity of the attenuation network can be altered. To adjust the probe, switch the probe to the x10 and attach the probe to a 1 kHz square wave signal.

  • Page 17: Driver Installation

    Before connecting the Handyscope HS3 to the computer, the drivers need to be installed. Introduction To operate a Handyscope HS3, 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.
  • Page 18 To remove the old driver successfully, it is essential that the Handyscope HS3 is disconnected from the computer prior to starting the driver install utility. When the Handyscope HS3 is used with an external power supply, this must be disconnected too. Chapter 4...
  • Page 19 Figure 4.2: Driver install: step 2 When the instrument is still connected, the driver install utility will recognize it and report this. You will be asked to continue anyway. Figure 4.3: Driver install: Instrument is still connected Clicking No will bring back the previous screen. The instru- ment should now be disconnected.
  • Page 20 Figure 4.4: Driver install: step 3 On Windows XP and newer, the installation may inform about the drivers not being ”Windows Logo Tested”. The driver is not causing any danger for your system and can be safely installed. Please ignore this warning and continue the installation. Figure 4.5: Driver install: step 4 The driver install utility now has enough information and can install the drivers.

  • Page 23: Hardware Installation

    5.1.1 External power In certain cases, it can be that the Handyscope HS3 cannot get enough power from the USB port. When a Handyscope HS3 is connected to a USB port, the hard- ware will be powered, resulting in an inrush current, which is higher than the nominal current.

  • Page 24: Connect The Instrument To The Computer

    After the new driver has been pre-installed (see chapter 4), the Handyscope HS3 can be connected to the computer. When the Handyscope HS3 is connected to a USB port of the computer, Windows will report new hardware. The Found New Hardware Wizard will appear.

  • Page 25: Found New Hardware Wizard

    Figure 5.1: Hardware install: step 1 This window will only be shown in Windows XP SP2 or newer. No drivers for the Handyscope HS3 can be found on the Windows Update Web site, so select No, not this time and click Next .
  • Page 26 Since the drivers are already pre-installed on the computer, Windows will be able to find them automatically. Select Install the software automatically and click Next . Figure 5.3: Hardware install: step 3 The New Hardware wizard will now copy the required files to their destination.

    The CH1 and CH2 BNC connectors are the main inputs of the ac- quisition system. The outside of the BNC connectors is connected to the ground of the Handyscope HS3. Connecting the outside of the BNC connector to a potential other than ground will result in a short circuit that may damage the device under test, the Handy- scope HS3 and the computer.
