OPERATING INSTRUCTIONS The SR552 Voltage Pre-Amplifier is designed to The SR552 (A) and (B) Inputs should now be be used with either the SR510/530 lock-ins as used as the lock-in voltage inputs. The input well as the newer DSP lock-ins. The SR552 switch selects single ended, (A), or differential, reduces the input noise and extends the full (A-B), operation. The input impedance is 100 scale sensitivity to 10 nV (without expand). kΩ , 25 pF. The connector shields are isolated When used as a r

DYN RES FS Sensitivity SR552 Gain USING THE SR552 WITH SRS DSP LOCK-INS The SR552 is not sensed by the DSP lock-ins. LOW > 50 mV 10 The DSP lock-in does NOT compensate for the 20 db 50 mV 20 gain of the preamp. The gain of the preamp is 20 mV 50 set to 10. Measurements made with the preamp < 20 mV 100 need to be divided by 100. NORM > 5 mV 10 The SR552 is AC coupled from 1 Hz to 100 kHz. 40 db 5 mV 20 Set the lock-in input to AC coupled since the 2 mV 50 signal must be above 1 Hz. Frequencies be

The gain will be 100 in this configuration. Grounding pin 3 will change the The SR552 without a lock-in gain to 50, and grounding pin 4 will change the The SR552 can be powered with an external gain to 20.
