SA600 series SA600 series preamplifiers for detection of sub nanoamp. signals achieve high gain and wide bandwidth that were previously not possible. Four models are available to match differing requirements for gain and frequency range. SA series amplifiers are suitable as head amplifiers for sensors of various types, and they are ideal for enhancing sensitivity of analyzers or measuring instruments. M (V/A) 0 M (V/A) DC to 0 khz 1 G (V/A) G (V/A) Both high gain and wideband have been achieved up to G(V/A) Four models are available with gains of M / 0 M / 1 G / G (V / A). Stable with capacitance of sensor and connection cable. SA600 series operates stably against input capacitance such as sensor s and connection cable s parallel capacitance. The overshoot and the ringing rarely occur for pulse response. Low Noise Not only high gain and wideband, the SA600 series also achieves a low noise of fa/ Hz ( 15 ) order. The SA600 series adopts SMA connectors for input and output with excellent shielding effectiveness. LPF Output The SA is equipped with a low pass filter to reduce high frequency noise. The high frequency noise can be reduced by selecting its frequency. SA604F2 ( M V/A) Cutoff frequency is selectable by the switch on the panel (4 selectable).
