Command Syntax Description
Set MZM Bias
Mode
MZM:MODE: N N is a positive integer between 0 and 9, inclusive. Set this value to
select the MZM bias mode. The mode associated with each value is:
0: Bias control is off. 0 V is applied to the MZM bias.
1: Auto Peak bias mode, which uses dither to maintain operation at
the peak of the modulation function.
2: Auto Null bias mode, which uses dither to maintain operation at
the lowest point (null) of the modulation function.
3: Auto Quad Pos bias mode, which maintains operation at the
positive quadrature position on the modulation function. This is
equivalent to using the touchscreen GUI to select Quad Mode and
positive slope, with dither on.
4: Auto Quad Neg bias mode, which maintains operation at the
negative quadrature position on the modulation function. This is
equivalent to using the touchscreen GUI to select Quad Mode and
negative slope, with dither on.
5: Hold Quad Pos bias mode, which holds the bias at the last
voltage found in Quad mode. It is equivalent to using the
touchscreen GUI to select Quad Mode and positive slope, with
dither off.
6: Hold Quad Neg bias mode, which holds the bias at the last
voltage found in Quad mode. It is equivalent to using the
touchscreen GUI to select Quad Mode and negative slope, with
dither off.
7: Manual Voltage bias mode, which is equivalent to using the
touchscreen GUI to select Manual Mode while the “bias” setting is
selected.
8: Auto Power Ratio Pos, which is equivalent to using the
touchscreen GUI to select Manual Mode while the “ratio” setting
and positive slope are selected.
9: Auto Power Ratio Neg, which is equivalent to using the
touchscreen GUI to select Manual Mode while the “ratio” setting
and negative slope are selected.
Get MZM Bias
Mode
MZM:MODE? Returns a positive integer between 0 and 9, inclusive, corresponding to
the current MZM bias mode. The mode associated with each value is
defined in the Set MZM Bias Mode description.
Trigger MZM
Calibration
MZM:RESET Triggers a MZM bias calibration and returns a 1. While the calibration is
running, the MZM:CAL? command returns a 1.
Get MZM
Status
MZM:SETpoint?
A 1 is returned and a steady green dot shows in the Bias field of the
instrument’s touchscreen when the MZM bias is stable and at setpoint.
A 0 is returned and the green dot in the Bias field blinks while the MZM
is not at setpoint.
Get Post-MZM
Power in dBm
MZM:TAP:DBM? Returns the optical power, as a floating point value in dB, output by the
MZM. This value is the scaled optical power measurement made at a
tap located at the output of the MZM.
Get Post-MZM
Power in mW
MZM:TAP:MW? Returns the optical power, as a floating point value in mW, output by
the MZM. This value is the scaled optical power measurement made at
a tap located at the output of the MZM.
Get MZM Bias
Voltage
MZM:Voltage? Returns the current MZM bias voltage as a floating point value in Volts.
