OPERATING INSTRUCTIONS  
The SR552 Voltage Pre-Amplifier is designed to  
be used with either the SR510/530 lock-ins as  
well as the newer DSP lock-ins. The SR552  
reduces the input noise and extends the full  
scale sensitivity to 10 nV (without expand).  
When used as a remote pre-amplifier, the  
SR552 can eliminate the effects of noise pickup  
on long signal cables.  
The SR552 (A) and (B) Inputs should now be  
used as the lock-in voltage inputs. The input  
switch selects single ended, (A), or differential,  
(A-B), operation. The input impedance is 100  
k, 25 pF. The connector shields are isolated  
from the chassis ground by 10 Ohms. These  
inputs are protected to 100 Vdc but the ac input  
should never exceed 10 V peak. The maximum  
input before overload is 70 mV rms. The  
OVERLOAD indicator will light whenever the  
pre-amplifier overloads. Note that overloads  
that occur after the pre-amplifier are indicated by  
the lock-in's overload indicator.  
Power and control are supplied to the SR552 via  
the 9 pin cable which is supplied with the unit.  
Attach one end of the cable to the connector on  
the rear of the SR552. With the lock-in power  
off, connect the other end of the cable to the  
PRE-AMP connector on the rear of lock-in. Both  
ends of the cable are equivalent. If a longer  
cable is required, any standard 9 pin cable will  
suffice since all connections are straight  
USING THE SR550 WITH THE SR510/530  
The SR510/530 lock-ins sense the presence of  
the SR552 through the power cable and takes it  
into account when setting the gain of its own  
amplifiers. Thus, to obtain the correct overall  
gain, the SR552 output must be connected to  
the voltage inputs of the lock-in.  
through. When the lock-in power is on, the  
POWER indicator on the SR552 will light.  
CONNECTING THE SR552  
The overall sensitivity of the lock-in plus the pre-  
amplifier is displayed as the sensitivity on the  
lock-in front panel. It is necessary to divide the  
displayed sensitivity by 10.  
The (A) Output of the SR552 should be  
connected to the (A) Input of the lock-in. For  
most applications, this single connection will be  
adequate. The lock-in Input Selector should be  
set to (A). For situations where there may be  
noise pick-up on this cable, it is better to connect  
the SR552 (B) Output (shielded pre-amp  
ground) to the (B) Input of the lock-in as well.  
The (A) and (B) cables should be twisted  
together to prevent inductive pick-up. The lock-  
in Input Selector should then be set to (A-B).  
The gain of the SR552 is 10, 20, 50, or 100.  
The gain is controlled by the lock-in and is set to  
maximize the pre-amplifier gain while  
maintaining the selected dynamic reserve. For  
most sensitivities, the pre-amplifier gain will be  
100. The following table summarizes the gain  
allocation.

USING THE SR552 WITH SRS DSP LOCK-INS  
The SR552 is not sensed by the DSP lock-ins.  
The DSP lock-in does NOT compensate for the  
gain of the preamp. The gain of the preamp is  
set to 10. Measurements made with the preamp  
need to be divided by 100.

The SR552 is AC coupled from 1 Hz to 100 kHz.  
Set the lock-in input to AC coupled since the  
signal must be above 1 Hz. Frequencies below 1

The common mode rejection of the SR552 is  
adjusted by the small screw on the right side of  
the enclosure. The CMR is set at the factory,  
however, it may be necessary to re-adjust it,  
particularly if there is one specific frequency  
which is important. The easiest way to peak the  
CMR is to use the internal oscillator of the lock-  
in (or any signal generator). Apply a reference  
signal to the lock-in REFERENCE INPUT.  
Apply a 100 mV signal to both the (A) and (B)  
inputs of the SR552. Check the SR552  
< 200 µV  
When the SR552 is connected, the full scale  
sensitivity can extend to 10 nV (no expand).  
The 10, 20, 50 nV sensitivities can be reached  
using the normal lock-in controls. If the SR552  
is disconnected while the sensitivity is below 100  
nV, the sensitivity will revert back to 100 nV.  
connections by switching the input selector to  
(A). The lock-in should read 100 mV (with the  
phase adjusted on the SR510). Now switch the  
SR552 to (A-B). Adjust the lock-in sensitivity to  
obtain a 50% output. Adjust the CMR screw on  
the SR552 to minimize the lock-in output. On  
the SR510, it is necessary to check the output  
when 90° of phase shift is added as well. On a  
From the computer interface, the presence of  
the SR552 can be determined using the 'H'  
command. Also, gain codes 1-3 are acceptable  
in the 'G' command to set sensitivities below 100  
nV. Pre-amplifier overloads are not detectable  
via the computer interface.

dual phase lock-in, use the R output to avoid  
phase shifts.  
All three voltages are required. Pins 7 and 8  
should be tied together. All other pins should be  
left open. The gain will be 100 in this  
configuration. Grounding pin 3 will change the  
gain to 50, and grounding pin 4 will change the  
gain to 20. Grounding both pins 3 and 4 will  
change the gain to 10.

The SR552 can be powered with an external  
power supply. Power is applied through the 9  
pin connector as described below.
