ERRors?	FRONT PANEL

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.

: ERR ?

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.

LASer:CALMD	FRONT PANEL

The LASer:CALMD command sets the laser's photodiode feedback responsivity (the CAL PD parameter).

<nrf

value>

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 IPD mode, when
	Constant P (MDP) mode is selected.
	The parameter should be set to 0 for IPD operation modes. Otherwise, the value of this
	parameter is used to convert between IPD and PPD 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 IPD
	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 PPD display to read 1 mW.
