We are measuring the noise level of SR560 at low frequency ( ~10mHz) , with the gain 1e4, AC couple, low pass 30 Hz. The  data is recorded by C3:PSL-GEN_DAQ14 channel.

 The input is terminated with a 50 ohm terminator. The setup of the SR560 under test (S/N 02785) is the same as the one we are using now.

Tomorrow we will measure the noise level of the whole setup (SR560, cables, all mixers and amplifiers included.)
