The LASer:CAL:LDI command is used to enter the LASER current setpoint,
measurement, and limit (in low bandwidth mode) calibration mode.
Syntax Diagram
Parameters None
Notes Since the limit circuit is the same for both high and low bandwidth modes, it is only
calibrated when low bandwidth mode is selected.
After this command is issued, the LDX-3232 High Compliance Current Source will allow
calibration of the current setpoint, measurement, and limit (if low bandwidth mode is
selected). This procedure is outlined in Chapter 6.
The calibration defaults to the selected bandwidth setting. Therefore, it is necessary to
select the desired bandwidth (I or I
HBW
) and turn the LASER output on before performing
the calibration for that bandwidth.
Calibration is performed at the current setpoint, wherever it is set. If the LASER output is
not on, E516 is displayed.
In remote operation, the LASer:CAL:LDI? query may be used to determine if the
LDX-3232 High Compliance Current Source is ready for the user to enter a value.
Examples "Las:CAL:LdI" -action: the LDX-3232 enters calibration mode for LASER current.
"Las:Cal:LDI" -action: the LDX-3232 enters calibration mode for LASER current.
