CHAPTER 4
The LASer:LDV command sets the laser voltage for calibration of the laser voltage measurement.
Parameters An <nrf value> which represents the (laser) output voltage, in volts.
Notes Set point is the same for both low and high bandwidth output modes and is entered only for LDV
calibration.
Examples "Las:LDV 4" −action: enters a value of 4.000 volts.
"LAS:ldv 1.025" −action: enters a value of 1.025 volts.
The LASer:LDV? query returns the value of the measured laser voltage.
Notes This measurement is updated approximately once every 600 msec.
Examples "LAS:ldv?" −response: 3.03, means the measured laser output voltage is 3.03 volts.
"Laser:LDV?" −response: 1.0, means the measured laser output voltage is 1.000 volt.
The LASer:LIMit:I1 command sets the LASER current limit value for the 100 mA range on the LDC−
3714B and the 2000 mA range on the LDC−3744B. (Not applicable for LDC−3724B).
Parameters An <nrf value> which represents the LASER limit current, in mA.
Notes The current limit is in effect in all modes of operation of the laser output with respect to the output
range (low/high).
Examples "LAS:LIM:I1 80" −action: the LASER current limit is set to 80 mA.
":Laser:Limit:I1 60" −action: the LASER current limit is set to 60 mA.
The LASer:LIMit:I1? query returns the value of the LASER current limit for the 100 mA range on the
LDC 3714B or the 2000 mA range on the LDC−3744B. (Not applicable for LDC−3724B).
Notes The current limit is valid for all modes of Laser operation.
Examples "LAS:LIM:I1?" −response: 40, means the laser current limit is 40 mA.
"Laser:LIM:I1?" −response: 500, means the laser current limit is 500 mA (LDC−3744B only).
