The LASer:BIAS? query returns the status of the selected laser channel's photodiode bias selection.
SYNTAX DIAGRAM
PARAMETERS
None. The response is an <nrf value>.
POINTS OF
INTEREST
Photodiode bias is turned off when a *RST command is issued.
EXAMPLES
"Las:BIAS?" -response: 0, means that the selected channel's photodiode bias is off.
"LAS:Bias?" -response: 1, means that the selected channel's photodiode bias is enabled.

The LASer:CALPD command sets the laser's photodiode feedback responsivity (the CAL PD parameter) on
the selected channel.
SYNTAX DIAGRAM
:
PARAMETERS
An <nrf value>, in microamps/milliwatt.
POINTS OF
INTEREST
Optical power (PPD) is calculated as the monitor photodiode current divided by this value.
EXAMPLES
"LAS:CALPD 0" -action: sets the CAL PD parameter to 0.
"Laser:Calpd 1" -action: sets the CAL PD parameter to 1.00 microamp/milliwatt: a photodiode
feedback current of 1 microamp will cause the P display to read 1 milliwatt.
