LDX-3232 Device-Dependent Command Reference

LASer:CAL:MDI?	FRONT PANEL
	REMOTE

The LASer:CAL:MDI? query is used to determine that the LDX-3232 is ready for a value to be entered during the calibration cycle of the LASer:CAL:MDI mode.

Notes		After this query is issued and a response of 1 is received, the LDX-3232 be ready for the
		user to enter a photodiode current value via the LASer:MDI command (see Chapter 6).
Examples		"LAS:CAL:MDI?" -response: 1, means the LDX-3232 is ready for the user to enter a
		photodiode current value via the LASer:MDI command.

LASer:COND?	FRONT PANEL
	REMOTE

The LASer:COND? query returns the value of the status condition register of the LASER operations.

: LAS : COND ?

-where the response is the sum of the following:

1	LASER Current Limit	256	Output is shorted
2	LASER Voltage Limit	512	Output is outside tolerance limit
4	N/A	1024	Output on/off state
8	Power limit	2048	Ready for calibration data state
16	Interlock disabled	4096	N/A
32	N/A	8192	N/A
64	Compliance Voltage Limit	16384	N/A
128	Open circuit	32768	N/A
Notes	The LASER conditions that are reported to the status byte are set via the
	LASer:ENABle:COND command.

The Open circuit condition is only present while the LASER output is on, and when the hardware detects this condition, it will turn the LASER output off. Therefore, the Open
