ACC SIGNAL SELECT
Provides a calibrated attenuation of the accelerometer signal. This function checks the Automatic Gain
Control (AGC) of the Electronic Test Set. In EXT position the external accelerometer BNC connector is
selected. This allows the user to route a signal from a second source (such as a synthesizer) to the
accelerometer interface. When using EXT mode be aware that the 54 mV/g accelerometers require about
a 5V offset on the signal to meet bias requirements.
