OUTPut

Subsystem Syntax

The OUTPut subsystem controls which output path (if any) will receive the synchronization pulses generated by the HP E1429. Sync pulses can be sent to the "Ext 1" BNC, the VXI TTL trigger lines, the VXI ECL trigger lines, or any combination of these three.

OUTPut :ECLTrg<n>

:FEED<source> [:STATe] <mode>

:EXTernal[1] :FEED<source> [:STATe] <mode>

:TTLTrg<n> :FEED<source> [:STATe] <mode>

:ECLTrg<n>:FEED

OUTPut:ECLTrg<n>:FEED <source> specifies the source for the synchronization pulse which will be routed to ECLTrg0 and/or ECLTrg1. The available sources are:

EXTernal[1]” : Outputs the signal currently specified by the OUTPut:EXTernal[1]:FEED command with the polarity inverted. OUTPut:EXTernal1:STATe ON must be set for output to occur. See the OUTPut:EXTernal[1]:FEED command for descriptions of the possible sources.

[SENSe[12]]:ROSCillator” : The signal level will go high with the falling edge of an external reference oscillator (SENSe:ROSCillator:SOURce EXTernal), and will go high with the rising edge of all other reference oscillator sources: SENSe:ROSCillator:SOURce (INT ECLT<n> CLK10). When the output state is enabled, the signal is output as soon as this feed is selected, and will be output continuously until the feed source is changed to some other selection.

TRIGger[:STARt:SEQuence[1]]” : Outputs an approximately 25 nanosecond wide positive going pulse each time a convert pulse (TRIGger) is sent to the A to D converter.
