The Handyscope HS3 is a powerful 100 MSa/s USB oscilloscope that can also be used as a multimeter, spectrum analyzer, data logger or protocol analyzer. This USB oscilloscope also contains a function / arbitrary waveform generator that is able to produce every signal that is needed. Together with the 2 measurement channels this oscilloscope is an excellent measurement tool to troubleshoot circuits.

Continuous streaming

Besides measuring in block mode, the Handyscope HS3 is also capable of performing continuous streaming measurements. This will create a continuous uninterrupted data stream to the computer. The data can then be displayed on the screen and/or saved to disk.

Data logger

Arbitrary Waveform Generator

The integrated Arbitrary Waveform Generator operates fully independent from the measuring system of the Handyscope HS3. It has a 50 MSa/s sampling clock, a 256K samples deep waveform memory, a 14 bit output resolution and a ± 12 V output range. The arbitrary function generator allows you to generate test signals for your measurements in any shape you like. Several standard signal shapes are available and it is possible to regenerate previously measured signals.

Combining multiple Handyscope HS3s

When one Handyscope HS3 does not offer enough input channels, the Handyscope HS3 can be coupled to one or more other instruments. This allows to make a combined instrument which will enable simultaneous measuring on all channels of all combined instruments.

Versatile Multi Channel oscilloscope software

The Handyscope HS3 is delivered with the versatile Multi Channel oscilloscope software, which transforms the Handyscope HS3 into an oscilloscope, spectrum analyzer, data logger, multimeter and protocol analyzer.

Some of the powerful features of the Multi Channel oscilloscope software are indicated below, for a full description of the Multi Channel oscilloscope software, refer to the Multi Channel oscilloscope software pages.

Touchscreen friendly toolbars

An oscilloscope toolbar and channel toolbars are available for each detected Handyscope. The convenient toolbars provide clear buttons for all settings of the oscilloscope and its channels. They show the current settings of the oscilloscope and allow to change all settings. The large buttons are very suitable for touchscreen operation.

The toolbars are fully configurable through the program settings. You can set the button size, add or remove buttons and change the order of the buttons.

Comprehensive Arbitrary Waveform Generator

To generate your test signals, the Multi Channel oscilloscope software also includes a comprehensive Arbitrary Waveform Generator.

An arbitrary waveform generator is an instrument that can generate repetitive or single shot signals. The signals can have a predefined standard shape like a sine wave or a square wave as in a conventional function generator. However, the signals can also have an arbitrary shape, defined by the user. These signals can be created using the Multi Channel oscilloscope software or an external program or can be signals previously measured by the Handyscope and loaded in the generator.

The Multi Channel oscilloscope software generator can be fully synchronized with the Multi Channel oscilloscope software oscilloscope, using the dedicated generator trigger signals, allowing the scope to trigger on the start of the generated signal, on each new period or on the end of the generated signal.

Flexible signal displays

The Multi Channel oscilloscope software scope, spectrum analyzer and datalogger offer an ultimately flexible way to display all aspects of the measured signals. They can have one or more graphs, each displaying one or more signals, where each graph can display different parts of a signal. Graphs can display the signal(s) of your Handyscope in Yt mode, in XY mode or as frequency spectrum, with or without interpolation. Colors of all items in a graph can be set to any required value. Graph dimensions can be adjusted to any required size, graphs can be located in one single window or in separate windows, which can be located anywhere on the desktop.

The multimeter in the Multi Channel oscilloscope software turns your Handyscope into a multimeter can be used to measure or monitor specific properties of a signal, like True RMS value, frequency, maximum value etc. The Multi Channel oscilloscope software multimeter can have any number of fully configurable displays, either displaying the measured value as a number or using a gauge display. When using a gauge display, it can be very helpful when adjusting a circuit for a specific property, e.g. adjusting an offset to zero.
