10µVp-p Square Wave
OSP-1 On Oscilloscope
10µV square wave displayed on 5mV/div oscilloscope



The OSP-1 is an AC/DC Coupled Amplifier extending the sensitivity of any oscilloscope up to 1000×! Since the maximum sensitivity of most oscilloscopes is 10mV/division, the OSP-1 extends the sensitivity 1000× to 10μV/division!

The difference input and a low pass filter are absolutely essential features for design or troubleshooting of sensitive electronic circuits, potential ground loops, testing of sensors and noise measurement. The DC offset may be employed for a minute difference signal measurement in the presence of high common mode or DC offset voltages.

The unit may be used as a temporary, general purpose preamplifier for a variety of experiments or tests in physics, chemistry, biology or other sciences.
