7 in 1 USB Test Instrument.

The Circuitgear CGR-101 from Audon Electronics is a PC-based instrument
that provides the features of seven devices in one USB-powered compact
box.


The device offers the performance of a two-channel 10-bit 20MSa/sec
2MHz oscilloscope, a two-channel spectrum-analyser, and a 3MHz 8-bit
arbitrary-waveform/standard-function generator with eight digital I/O
lines. It also functions as a network analyser, a noise generator and a
PWM output source. Its open-source software runs with Windows, Linux and
Mac OS.

The CGR-101's oscilloscope capability provides a two-channel 10-bit
-+/-0.25Vp-p to +/-25Vp-p 2MHz basic scope, but with sophisticated
marker measurements, triggering (normal, auto, single-shot and
pre-trigger) with time-base adjustable from 50ns/division to
100ms/division. With a 1k sample/channel data buffer, the user can even
view pre-trigger signals.

The CGR-101's two-channel FFT spectrum analyser feature offers marker
measurements, and when used with the internal signal generator, displays
Bode plots and performs vector network analysis, showing gain and phase
values.

The CGR-101's signal generator is an 8-bit 0.1Hz to 3MHz signal source,
offering sine/square/triangle/ramp waveforms, as well as being capable
of outputting arbitrary or preloaded waveforms such as ECGs. The user
can enable the generator, connect its signal to a circuit and perform
measurements with the oscilloscope and/or spectrum analyser. The
generator can also be set to function as a white noise source. A
slider-controlled PWM generator is also provided, with mark-space ratio
clearly displayed.

The included visual interface software enables simple control and
display of information. The oscilloscope, generator, and digital I/O are
operated from a custom open-source Tcl/Tk software GUI included with the
hardware. As the software is open source, the code can be read and even
added to or customised.The CGR-101 is also Labview compatible and can be
controlled by any serial-port-driving software, such as Matlab or Visual
Basic.
