              PERFORMANCE
              The Model 7000 and 7008 Low Noise Differential Preamplifiers provide a high gain amplification to 1MHz with an AC output derived from a very low noise FET instrumentation amplifier. Each model  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 (7000 model only). Noise referred to input is 7nV√Hz and common mode rejection is >100dB at 1kHz. Momentary pushbutton 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 7008 eight channel Low Noise Differential Preamplifier offers up to 8 channels of high gain pre-amplification with USB or LAN remote control.

              APPLICATIONS
              The Model 7000 and 7008 are very useful for troubleshooting sources of noise, amplifiers, power supplies and various other electronic circuits. They are an excellent tool as a preamp for amplifying low level input signals to oscilloscopes or other devices.
