The input impedance is 10 M, and minimum fullscale input voltage sensitivity is 2 nV. The input can also be configured for current measurements with selectable current gains of 10 6 and 10 8 VA.

However, the SR830 only gives me Mar 10, 2015 The Zurich Instruments MFLI is a digital lockin amplifier that sets the new standard for measurements in the medium and low frequency range.
The MFLI is available in two versions covering the frequency range DC to 500 kHz and DC to 5 MHz (an upgrade from 500 kHz to 5 MHz is possible later). The SR830 simultaneously displays the magnitude and phase of a signal, while the SR810 displays magnitude only.
Both instruments use digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lockins. Lockin amplifier laboratory. Lockin amplifer instruction can be found on the website for Stanford Research Systems.
