5 Polarization Commands
Command: :POLarimeter:SWEep:CONTinuous:SACCuracy?
Syntax: :POLarimeter:SWEep:CONTinuous:SACCuracy?
Description: Returns the SOP accuracy in rad used in the continuous sampling mode.
Parameters: None
Response: SOP accuracy in rad
Example: :pol:swe:cont:sacc? → +0.00000000E+00
Affects N7781C / N7786C / N7788C
Command: :POLarimeter:TRIGger:INPut
Syntax: :POLarimeter:TRIGger:INPut<wsp><value>
Description: Defines the trigger input
Parameters: NONE: Don't wait for trigger
TTLHIGH: Wait for rising edge on BNC input
TTLLOW: Wait for falling edge on BNC input
SOPCHANGE: Wait for specified change of SOP
PRETRIGGER_TTLHIGH: Specified numbers of samples are logged before rising edge on BNC input
PRETRIGGER_TTLLOW: Specified numbers of samples are logged before falling edge on BNC input
SMEasure: One sample for every trigger will be logged
CMEasure: One trigger excutes one loop with specified number of samples
MMEasure: One trigger executes specified number of loops with specified number of samples
THReshold: Define minimum and maximum treshold power limits for triggering. You have to pass two paramters additionally.
If you don't want minimum or maximum limit, send NAN instead of number.
Example: :pol:trig:inp NONE pol:trig:inp THR,1mW,5mW
Affects N7781C / N7786C / N7788C
Command: :POLarimeter:TRIGger:DELay
Syntax: :POLarimeter:TRIGger:DELay<wsp><value>
Description: Defines factor for delay. delay = factor/32 MHz
That means, trigger event is excuted after specified time after input trigger.
