COMMAND REFERENCE
LDX-3232 Device-Dependent Command Reference
04_06 LDX-3232 41
CHAPTER 4
The ERRors? query returns a list of command and device errors that have occurred
since the last query. These errors are notated by a number that corresponds to the type
of error that occurred. See Chapter 3 for information regarding error handling.
Syntax Diagram
Parameters None.
Notes The response data will be a list of the current errors. The errors are represented by
numbers and are separated by commas. A response of 0 indicates that no errors were
reported. The response data is sent as character data. Up to 10 error codes are stored
between error queries.
Examples "ERR?" -response: 0, means no errors reported.
"Errors?" -response: 201, means that the <PROGRAM DATA> (parameter) value out of
range error was reported since the last ERR? query.
The LASer:CALMD command sets the laser's photodiode feedback responsivity
(the CAL PD parameter).
Syntax Diagram
Parameters An <nrf value>, in mA/mW. The range is 0 to 1000.
Notes If the parameter is set to 0, the LDX-3232 will operate in a constant I
PD
mode, when
Constant P (MDP) mode is selected.
The parameter should be set to 0 for I
PD
operation modes. Otherwise, the value of this
parameter is used to convert between I
PD
and P
PD
values. The units of this parameter are
mA/mW.
Examples "LAS:CALMD 0" -action: sets the CAL PD parameter to 0. This enables the constant I
PD
mode of operation.
"Laser:Calmd 1" -action: sets the CAL PD parameter to 1.00 mA/mW. Therefore, a
photodiode feedback current of 1 mA will cause the P
PD
display to read 1 mW.
