TWO WAYS OF PROGRAMMING
The amplifier settings – e.g. phase, gain, time constant – are controlled either by switches directly on the amplifier module or externally using a standard digital I/O computer board. The variable working frequency is determined by an external reference signal which may be e.g. the synchronization signal of a chopper wheel or the modulation signal of a laser. The current input is well suited for amplifying signals from high impedance sources like photodiodes or PMTs while the voltage input can be used to measure signals from low impedance sources like pyros or coils.
