Using Sr510 Programs - Stanford Research Systems SR810 Manual

USING SR510 PROGRAMS WITH THE SR810
The SR810 responds to most SR510 programming commands. This allows the SR810 to drop into an
existing SR510 application with a minimum of program changes. Of course, some changes will be required
and some features are unique to one instrument or the other. For example, SR510 commands can not put the
SR810 into a configuration which is not allowed by the SR810. All program routines which query the
SR510 status MUST be rewritten to query the equivalent SR810 status using the SR810 status
commands.
The SR510 emulation mode is intended to facilitate the transition to the SR810. New applications programs
should use the SR810 commands in order to take advantage of all of the SR810 features.
The SR565 program will NOT run reliably with the SR810. This is because the SR565 is optimized for
speed and the SR810 command execution time for some commands is longer than in the SR510.
The SR510 commands are documented in the SR510 manual. SR510 command parameters follow the
SR510 conventions. Exceptions are noted below.
OUTX i
FMOD i
A {n}
B {n}
C {n}
D {n}
E {n}
F {x}
G {n}
H
The SR810 OUTX i command sets the output interface to RS-232 (i=0)
or GPIB (i=1). The OUTX i command MUST be at the start of ANY
SR810 program to direct responses to the interface in use.
The SR510 is always in external reference mode. Use the FMOD 0
command to set the SR810 to external reference. To use the SR810
internal oscillator, use the FMOD 1 command.
The A1 command auto offsets X. The A0 command and the A query
are not implemented.
The SR810 has no bandpass filter. This command is emulated but no
changes are made to the SR810 configuration.
Changes the Reference display.
Change the dynamic reserve. Unlike the SR510, all reserves are
allowed at all sensitivities.
Change the output expand. n=2 selects expand by 100.
The F command Reads the frequency. The F x command sets the
internal oscillator frequency to x Hz.
Change the sensitivity from 10 nV (n=1) to 500 mV (n=24). Settings
below 100 nV are always allowed. The 1V sensitivity can be set
using G25. Querying this sensitivity returns a value of 24.
The SR810 does not sense the pre-amplifier. This command is
emulated and always returns 0.
