SR510 Command List

The first letter in each command sequence is the command. The rest of the sequence consists of parameters. Multiple parameters are separated by a comma. Those parameters shown in {} are optional while those without {} are required. Variables m and n represent integer parameters while v represents a real number. Parameters m and n must be expressed in integer format while v may be in integer, real, or floating point format.

A {n}

If n is "1", the A command causes the auto offset routine to run. Every time an "A 1" command is received, the auto offset function is executed. If n is "0", then the auto offset is turned off. If n is absent, then the auto offset status is returned. Note that if the manual offset is on, an "A 1" command will turn off the manual offset before executing the auto offset function.

B {n}

If n is "1", the B command sets the bandpass filter in. If n is "0", the bandpass filter is taken out. If n is absent, then the bandpass filter status is returned.

C {n}

If n is "1", the C command sets the reference LCD display to show the phase setting. If n is "0", the LCD will display the reference frequency. If n is absent, the parameter being displayed (frequency or phase) is returned. Note that the P and F commands are used to read the actual values of the phase and frequency.

D {n}

If n is included, the D command sets the dynamic reserve. If n is absent, the dynamic reserve setting is returned.

1 NORM

2 HIGH

Note that not all dynamic reserve settings are allowed at every sensitivity.

E {n}

If n is "1", the E command turns the output expand on. If n is "0", the expand is turned off. If n is absent, the expand status is returned.

F

The F command reads the reference frequency. For example, if the reference frequency is 100 Hz, the F command returns the string "100.0". If the reference frequency is 100.0 kHz, the string "100.0E+3" is returned. The F command is a read only command.

G {n}

If n is included, the G command sets the gain (sensitivity). If n is absent, the gain setting is returned.

Note that sensitivity settings below 100 nV are allowed only when a pre-amplifier is connected.

H

The H command reads the pre-amplifier status. If a pre-amplifier is connected, a "1" is returned, otherwise, a "0" is returned. The H command is a read only command.

I {n}

If n is included, the I command sets the remote- local status. If n is absent, the remote-local status is returned.
