  • Page 2 Use a good isolation transformer or a dif- ferential probe when measuring at the line voltage or at grounded power supplies! A short-circuit current will flow if the ground of the Handyscope HS4 is connected to a positive voltage. This short-circuit current can damage both the Handyscope HS4 and the computer.

  • Page 7: Declaration Of Conformity

    Koperslagersstraat 37 8601 WL Sneek The Netherlands EC Declaration of conformity We declare, on our own responsibility, that the product Handyscope HS4-5MHz Handyscope HS4-10MHz Handyscope HS4-25MHz Handyscope HS4-50MHz for which this declaration is valid, is in compliance with EC directive 2011/65/EU (the RoHS directive)
  • Page 8 In order to avoid release of such substances into the environment and to reduce the use of natural resources, recycle the Handyscope HS4 in an appropriate sys- tem that will ensure that most of the materials are reused or recycled appropri- ately.

    48 kSa/s Table 3.2: Maximum streaming rates With the accompanying software the Handyscope HS4 can be used as an oscil- loscope, 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.

  • Page 10: Sampling Rate

    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. Figure 3.1: 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.

    Figure 3.3: The effect of the sampling rate 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 recon- struct 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 thor- oughly.

  • Page 12: Digitizing

    Figure 3.4: Aliasing In figure 3.4, 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 sam- pling interval is 1/1000Hz = 1ms. The positions at which the signal is sampled are depicted with the blue dots.

  • Page 13: Signal Coupling

    When measuring DC signals, make sure to set the signal coupling of the input to DC. Probe compensation The Handyscope HS4 is shipped with a probe for each input channel. These are 1x/10x selectable passive probes. This means that the input signal is passed through directly or 10 times attenuated.
  • Page 14 When using an oscilloscope probe in 1:1 the setting, the bandwidth of the probe is only 6 MHz. The full bandwidth of the probe is only obtained in the 1:10 setting The x10 attenuation is achieved by means of an attenuation network. This atten- uation network has to be adjusted to the oscilloscope input circuitry, to guaran- tee frequency independency.

  • Page 15: Driver Installation

    Computers running Windows 10 When the Handyscope HS4 is plugged in into a USB port of the computer, Win- dows will detect the instrument and will download the required driver from Win- dows Update. When the download is finished, the driver will be installed automat- ically.
  • Page 16 To remove the old driver successfully, it is essential that the Handyscope HS4 is disconnected from the computer prior to starting the driver install utility. When the Handyscope HS4 is used with an external power supply, this must be disconnected too.

    Figure 7.1: Rear panel Power The Handyscope HS4 is powered through the USB. If the USB cannot deliver enough power, it is possible to power the instrument externally. The Handyscope HS4 has two external power inputs located at the rear of the instrument: the dedicated power input and a pin of the extension connector.

  • Page 24: Power Adapter

    The Handyscope HS4 is equipped with a USB 2.0 High speed (480 Mbit/s) interface with a fixed cable with type A plug. It will also work on a computer with a USB 1.1 interface, but will then operate at 12 Mbit/s.
