Description:
Get the external trigger delay after changing the SOP value
Parameters:
None
Response:
Integer value (0-32766) 1 means 1/32 us
Example:
:PCONtroller:SEQuence:HOLDoff? +1
Affects
N7785C / N7786C / N7788C
Command:
:PCONtroller:SEQuence
Syntax:
:PCONtroller:SEQuence<wsp><488.2 Binary Block>
Description:
Sets the polarization controller sequence using waveplate positions and retardations. The parameter list is a series of
floating point values. Each waveplate is controlled by two float values: Orientation in rad and Retardation in fractions of
Lambda (0.25 corresponds to Lambda 4).
Thus, each sequence row contains 12 float values. Hence, the series length has to be a multiple of 12. The order is given by:
Orientation Waveplate 1, Retardation Waveplate 1, Orientation Waveplate 2, Retardation Waveplate 2, Orientation
Waveplate 3, Retardation Waveplate 3, Orientation Waveplate 4, Retardation Waveplate 4, Orientation Waveplate 5,
Retardation Waveplate 5, Orientation Waveplate 6, Retardation Waveplate 6
