The power entry module is used to fuse the AC line voltage input, select
the line voltage, and block high frequency noise from entering or exiting
the instrument. Refer to the first page of this manual for instructions on
selecting the correct line voltage and fuse.
The 24 pin IEEE-488 connector allows a computer to control the SR810
via the IEEE-488 (GPIB) instrument bus. The address of the instrument
is set with the [Setup] key.
The RS-232 interface connector is configured as a DCE (transmit on pin
3, receive on pin 2). The baud rate and parity are programmed with the
[Setup] key. To connect the SR810 to a PC serial adapter, which is
usually a DTE, use a straight thru serial cable.
These are auxiliary analog inputs which can be digitized by the SR810.
The range is -10.5 V to +10.5 V and the resolution is 16 bits (1/3 mV).
The input impedance is 1 MΩ.
The AUX 1 and 2 inputs may be displayed on the CH1 display. These
inputs allow signals other than the lock-in outputs to be acquired (and
stored). Furthermore, ratio quantities such as X/Aux1 may be displayed
(and stored).
These are auxiliary analog outputs. The range is -10.5 V to +10.5 V and
the resolution is 1 mV. The output impedance is <1 Ω and the output
current is limited to 10 mA.
These outputs may be programmed from the front panel ([Aux Out])or
via the computer interfaces.
The X and Y lock-in outputs are always available at these connectors.
The bandwidth of these outputs is 100 kHz. A full scale input signal will
generate ±10V at these outputs. The output impedance is <1 Ω and the
output current is limited to 10 mA.
These outputs are affected by the X and Y offsets and expands. The
