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.

Do not use the equipment if it does not operate properly. Have the equip- ment inspected by qualified service personal. If necessary, return the equip- ment to TiePie engineering for service and repair to ensure that safety fea- tures are maintained.
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)

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.
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.
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.
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.

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.
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.

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.
In order to power the Handyscope HS4 externally, an external power input is pro- vided for. It is located at the rear of the Handyscope HS4. Refer to paragraph for specifications of the external power intput.
HS4. 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 Handyscope HS4 and the computer. Power indicator A power indicator is situated at the top cover of the instrument. It is lit when the Handyscope HS4 is powered.
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.
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.
