Description [Hide]

This small, portable, two-channel digital oscilloscope has a powder-coated aluminum case and three pairs of probes. The hardware connects to your PC with the included USB cable for both data transfer and power, so no external power supply is needed. All oscilloscope controls are managed through a point-and-click PC software interface. Three easy-to-use cursor functions measure acquired signals, with the option to snap to the waveform. The cursors operate in zoom mode, allowing close viewing and precise measuring of signals. Other classic scope features include variable trigger voltage, external triggering, waveform measurements (min, max, frequency, period), and four FFT function options. The ability to save customized setups and quality bitmap screen captures are standard in the software.
