Channel Autoscale

This example saves the trigger and horizontal settings prior to performing :AUToscale so they can be re-set.

SUB channel_autoscale_86100a(@Dca)

REAL Level,Delay,Scale

OUTPUT @Dca;”:TRIGger:LEVel?” ! Ask for trigger level

ENTER @Dca;Level

OUTPUT @Dca;”:TIMebase:DELay?;SCALe?” ! Ask for horizontal delay and scale

ENTER @Dca;Delay,Scale

OUTPUT @Dca;”:AUToscale” ! Perform Autoscale

OUTPUT @Dca;”:TRIGger:LEVel”,Level ! Re-set trigger level

OUTPUT @Dca;”:TIMebase:DELay”,Delay;”;SCALe”,Scale ! Re-set delay and scale

SUBEND

Setting the Trigger Level

This subprogram selects different mnemonics to set the trigger level for either DCA platform.

SUB Set_trigger_level( REAL Level, @Dca ) ! Pass in Trigger Level and I/O Path

DIM Trigger_source$[15]

IF FNGet_model$(@Dca)=”83480A” THEN

OUTPUT @Dca;”:SYST:LONG OFF;HEAD OFF”

OUTPUT @Dca;”:TRIG:SOUR?” ! Get the active source, should be “TRIG2” or “TRIG4”

ENTER @Dca;Trigger_source$

OUTPUT @Dca;”:TRIG:LEV “;Trigger_source$;”,”;Level

ELSE ! Must be “86100A”

OUTPUT @Dca;”:TRIG:LEV “;Level ! Easy as pie

END IF

SUBEND

Setting the Trigger Source

The following example shows how to implement a Trigger Setup routine that works for either the 86100A or 83480A. The

function could use the new 86100A syntax to program either the 83480A or 86100A. No error checking is performed, but

it would be simple to ensure the correct syntax is used for each model.

SUB Set_trigger_source( Trigger_source$, @Dca ) ! Pass in Trigger Source and I/O Path

! Use new 86100A mnemonics for Trigger_source$

! FPANel - Front Panel (86100A only)

! LMODule - Left Module (Used to be TRIGger2 for 83480A)

! RMODule - Right Module (Used to be TRIGger4 for 83480A)

! FRUN - Free Run (Used to be :TRIGger:SWEep FREerun for 83480A)

DIM Mnemonics$[255]

! Trim and truncate Trigger_source$
