PERFORMANCE
The Model 7000 Low Noise Differential Preamplifier provides a high gain amplification to 1MHz with an AC output derived from a very low noise FET instrumentation amplifier and an optional DC (RMS-to-DC converted) output. The Model 7000 has fixed gain settings of x1 (0dB), x10 (20dB), x100 (40dB) and x1000 (60dB) over a selectable bandwidths of 100Hz, 1kHz (HP), 3kHz, 30kHz, 100kHz and 1MHz (LP Off). Noise referred to input is 7nV√Hz and common mode rejection is >100dB at 1kHz. The Model 7000 provides momentary pushbutton switches that control coupling, bandwidth, gain and channel on/off selections. BNC connectors are provided for single-ended and differential input, ac output, and dc output (optional) connections.

APPLICATIONS
The Model 7000 is very useful for troubleshooting sources of noise, amplifiers, power supplies and various other electronic circuits. The Model 7000 is an excellent tool as a preamp for amplifying low level input signals to oscilloscopes or other devices.
