REMOTE PROGRAMMING
4-7
SR715/720 will use the nominal value from the next lowest numbered bin with
a non-zero nominal value (several bins can have the same nominal value
without entering the value for each bin). The lowest numbered active bin must
have its nominal value set. Bin 0 must always be set for binning to be
enabled. The BNOM? i query returns the nominal value for bin i.
SETUP and CONTROL COMMANDS
* IDN?
The
*
IDN? common query returns the SR715/720's device configuration. This
string is in the format: "StanfordResearchSystems,SR7XX,YYYYY,ZZZ".
Where "YYYYY" is the five digit serial number of the unit, and "ZZZ" is the 3
digit firmware revision number.
*
OPC(?)
The
*
OPC (operation complete) common command/query is used to
synchronize command execution to the SR715/720's measurement process.
The
*
OPC command will set a bit in the Standard Event Status Byte when all
measurements in progress are complete. The
*
OPC? query will return the
value 1 when all measurements in progress are complete. For example, the
commands STRT;
*
OPC? would start a measurement and return a 1 when it
was done. The controlling program would then know that the answer was
ready to retrieved.
* RCL i
The
*
RCL command recalls stored setting number i, where i may range from
0 to 9. If the stored setting is corrupt or has never been stored, an execution
error will be generated.
*
RCL0 recalls the default setup.
*
RST
The
*
RST common command resets the SR715/720 to its default
configurations.
* SAV i
The
*
SAV command saves the current instrument settings as setting number
i (1-9).
*
WAI
The
*
WAI common command is a synchronization command that halts
further command processing until all measurements in progress are
complete. For example, the commands STRT;
*
WAI;XALL? would start a
measurement, halt further command processing until the measurement was
complete, and then execute the XALL? command to return the measurement
result.
STATUS REPORTING COMMANDS
*
CLS
The
*
CLS common command clears all status registers. This command
does not
affect the status enable registers.
*
ESE (?) {i}
The
*
ESE i command sets the standard event status byte enable register to
the decimal value i (0-255). The
*
ESE? query returns the value (0-255) of the
status byte enable register.
* ESR? {i}
The
*
ESR? command queries the value of the standard event status byte.
The value is returned as a decimal number from 0 to 255. The
*
ESR? i query
returns the value (0 or 1) of bit i (0-7). Reading the entire byte will clear it
while reading bit i will clear just bit i.
* PSC (?) {i}
The
*
PSC common command sets the value of the power-on status clear bit.
If i = 1 the power on status clear bit is set and all status registers and enable
registers are cleared on power up. If i = 0 the bit is cleared and the status
