COMMAND REFERENCE

LDX-3232 Device-Dependent Command Reference

LASer:TOLerance?

FRONT PANEL

 

 

REMOTE

The LASer:TOLerance? query allows the programmer to determine how the LASER current tolerance is set.

 

:

LAS

:

TOL

?

 

- where the response consists of two values, the first is the current tolerance in mA and

 

the second is the time window, in seconds.

 

 

Notes

The tolerance of the LDX-3232 LASER current may be used to delay programming after

 

an "LASer:OUTput 1" command is issued or the setpoint is changed.

 

A change of the output into or out of tolerance flag sets a flag in the LASER status event

 

register and so entering or exiting LASER current tolerance may be used to generate

 

service requests.

 

 

 

 

Examples

"Las:Tol?" -response: "0.2,5.0", means the LDX-3232 has a LASER current tolerance

 

setting of 0.2 mA with a time window of 5.000 seconds.

 

"LASER:TOL?" -response: "1.0,20.0", means the LDX-3232 has a LASER current tolerance setting of 1.0 mA with a time window of 20.000 seconds.

MESsage

FRONT PANEL

REMOTE

The MESsage command allows the user to enter an ASCII string of up to 16 non-NULL characters. This command may be useful for storing messages that relate to a test or configuration.

:MES

<white

space>

<ascii

string>

Parameters

An ASCII string that is 1 - 16 bytes in length.

 

Notes

The message may contain any ASCII character, but will be terminated when a NULL

 

terminator character is received. If the message has less than 16 bytes, the software will

 

fill the remaining message space with the space character. After 16 bytes have been

 

entered, the software will null-terminate the string.

Examples

MESSAGE "This is a test." -action: The string, "This is a test. " will be stored in

 

non-volatile memory.

 

 

Mes "Test 3" -action: The string, "Test 3

" will be stored in non-volatile memory.
