Educational USB Lab Instrument With Six-In-One Function for Under $100

We just introduced the new CGM-101 CircuitGear Mini - a unique, low-cost PC-based instrument which provides the features of six devices in one USB-powered compact box: 2-channel 11-bit 2MSa/sec 200kHz oscilloscope, 2-channel spectrum analyzer, 2MSa/s 8-bit arbitrary-waveform/standard-function generator with 8 digital I/O lines. It also functions as a network analyzer, and a PWM output source – all for less than $100! The oscilloscope and waveform generator can also work together to form a vector network analyzer. The USB interface allows the recording, output and printing of all waveforms or even updating the firmware as new features become available.

The CGM-101 CircuitGear Mini’s Oscilloscope capability provides a two-channel 11-bit 20mV/div to 5V/div (+/-0.25Vp-p to +/-25Vp-p with 1X Probe; +/250Vp-p with 10X Probe) 200kHz basic scope, also offering sophisticated marker measurements, and triggering (normal, auto, single-shot and pre-trigger) with a time-base adjustable from 500ns/division to 20s/division. A 1k sample/channel data buffer allows pre-trigger signal or “strip-chart” viewing. X-Y Plot, spectrum analysis, and waveform math are also included.  The two-channel FFT spectrum analyzer offers marker measurements, and, when used with the internal signal generator, displays Bode plots and performs vector network analysis, showing gain and phase values in real-time.
