DC to 1 MHz Low Noise Differential Preamplifier

Krohn Hite 7000 Image
The Krohn Hite 7000 Low Noise Differential Preamplifier provides high gain amplification to 1MHz with an AC output derived from a very low noise FET instrumentation amplifier.

The 7000 has fixed gain settings of x1 (0 dB), x10 (20 dB), x100 (40 dB) and x1000 (60 dB) over selectable bandwidths of 100 Hz, 1 kHz (HP), 3 kHz, 30 kHz, 100 kHz and 1 MHz. Noise referred to input is 7 nV/Hz and common mode rejection is >100 dB at 1 kHz.

Momentary push-button switches are provided 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.

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