8. 0 Hz and a 2x line filter 100 Hz or 120 Hz are provided to eliminate line related interference However unlike conventional lock in amplifiers no tracking band pass filter is needed at the input This filter is used by conventional lock ins to increase dynamic reserve Unfortunately band pass filters also introduce noise amplitude and phase error as well as drift The DSP based design of these lock ins has such inherently large dynamic reserve that no tracking band pass filter is necessary 3 1 2 Extended Dynamic Reserve The dynamic reserve of a lock in amplifier at a given full scale input voltage is the ratio in dB of the largest interfering signal to the full scale input voltage The largest interfering signal is defined as the amplitude of the largest signal at any frequency that can be applied to the input before the lock in cannot measure a signal with its specified accuracy Conventional lock in amplifiers use an analog demodulator to mix an input signal with a reference signal Dynamic reserve is limited to about 60 dB and these instruments suffer from poor Stability output drift and excessive gain and phase error Demodulation in the SR810 Lock In Amplifier is accomplished by sampling the input signal with a high precision A D converter and multiplying the digitized input by a synthesized reference signal This digital demodulation technique results in more than 100 dB of true dynamic reserve no prefiltering It is free of the er
