The
Stingray™ dual-channel PC digital oscilloscope adapter from
Saelig, Pittsford, NY, is powered solely from a USB port and combines
the functions of an oscilloscope, data logger, spectrum analyzer,
volt meter, frequency meter, and signal generator in one device.
It features simultaneous 12-bit sampling on both channels, a native
sampling rate of 1 MS/sec, 32 Kbytes of sample buffer, and hardware
triggering including delayed time base and pulse width. The device
has a third channel that can be configured as a waveform generator
output or an external trigger input. Stingray comes with EasyScope
II oscilloscope software for signal display, and EasyLogger software
that provides continuous PC data-logging capabilities. Using standard
scope probes, the input voltage range is ±50V, with voltage
scaleable from 10mV/div to 2V/div.
