Each model  has fixed gain settings of x1 (0dB), x10 (20dB), x100 (40dB) and x1000 (60dB) over 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.
