Noise measured on channel D Front-end Amplifier, pin 6, using a 10X
scope Probe going into the SRS560 Low noise Preamplifier, set for a gain
of 5E4. The output of the SRS560 Amplifier goes past the input of the
SRS770, FFT Network Analyzer, into channel 1 of a Tektronix Model
TDS420A, 4- Channel Digitizing Oscilloscope.
