:MEASure

Most of the measurement subsystem is available with the 86100A. The few exceptions can be accomplished using the

other commands built in to the 86100A, including the use of the histograms. Examples are included in the Appendix. The

following measurements are not supported in the 86100A but can be made using other methods built in to the 86100A.

Refer to the 83480A User’s Guide for detailed information on the definition of these measurements.

:MEASure:FREQuency

:MEASure:NWIDth

:MEASure:PREShoot

:MEASure:PWIDth

:MEASure:STATistics

:MEASure:VUPper

:MEASure:VMIDdle

:MEASure:VLOWer

Extinction Ratio Calibration

The Extinction Ratio calibration function was contained in the :MEASure subsystem, but has been moved to the :CALibrate

subsystem in the 86100A.

83480A :MEASure:CGRade:ERCalibrate

86100A :CALibrate:ERATio:STARt CHANnelN

:CALibrate:CONTinue or :CALibrate:CANCel

The status of the dark calibration can be checked with :CALibrate:ERATio:STATus <CHANnelN> and the dark level that was

characterized during the calibration can be queried with :CALibrate:ERATio:DLEVel? <CHANnelN>.

:TRIGger

The trigger subsystem was changed slightly, to add support for the new front panel input, and to simplify the remaining

vintage module programming.

Trigger Source and Sweep

The 83480A had two functional sources the trigger on channel 2 of the left module, or channel 4 of the right module. For the

sweep type, :TRIGgered or FREerun. The 86100A-default trigger is the new front panel connector, and identifies “Freerun”

as a source, rather than a trigger mode. The 86100A also provides support for 83480A modules, so it can identify those

modules as trigger sources.

83480A :TRIGger:SOURce TRIGgerN

:TRIGger:SWEep {TRIGgered | FREerun }

86100A :TRIGger:SOURce {FPANel | LMODule | RMODule | FRUN}

Trigger Level

The 83480A specified different trigger levels for each of the trigger sources. The trigger source was identified as TRIGger2

for the trigger input on the left module or TRIGger4 for the right module.

The Agilent 86100A specifies only one trigger level, no matter what source.

83480A :TRIGger:LEVel TRIGgerN,<level>

86100A :TRIGger:LEVel <level>

:TRIGgerN

Similar to the source and sweep commands, the 86100A simplifies the bandwidth settings. The 83480A specified which

trigger channel had a specific bandwidth, the 86100A specifies bandwidth for the entire trigger system. The 86100A also

separates the :GATed function into a new subcommand.

83480A :TRIGgerN:BWLimit {ON | 1 | OFF | 0 | DIVided | GATE}

86100A :TRIGger:BWLimit {HIGH | LOW | DIVided}

:TRIGger:GATed {ON | 1 | OFF | 0}
