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