Sets the laser compliance voltage limit.
One <nrf value> specifying the compliance voltage limit in Volts.
The voltage limit setting is useful for laser protection. When the maximum operating
voltage of a laser is known, the user may set the voltage limit to a value slightly higher
than the maximum operating voltage. Then, if the laser is accidentally disconnected, the
current source will quickly sense the over-voltage and shut off.
"LAS:LIM:V 5.0", -action: sets the compliance voltage limit to 5.0 V.
":Laser:limit:V 4.7", -action: sets the compliance voltage limit to 4.7V.
Returns the value of the laser compliance voltage limit setting.
None.
The voltage limit is active in all operational modes.
"las:lim:v?" -response: "6.7", means the compliance voltage limit is set to 6.7 V.
Returns LIV data from memory in groups of 25 points each time the command is
executed. For each current setpoint step, photodiode current, laser current setpoint, and
laser forward voltage values are saved to memory.
None.
If the data buffer is empty, executing the command will return "empty". The respective
data is erased after each execution of the command. The data is pulled in blocks up to
25 data points long with each execution of the command.
"LAS:LIV:GETMEAS?" - response: "3, 5.00, 1.51, 120, 10.00, 1.81,
144,15.00,2.14,172,20.00,2.31,207,25.00,2.48" means data from a five point LIV run
with pd current (A), laser current setpoint (A), and laser forward voltage (V) data for
each laser setpoint value from 5.00 amps to 25.00 amps.
