Agilent Technologies E1441A Sync?, TRIGger:IMMediate, TRIGger:STATe?, TTLTrg<n>:STATe

:SYNC

OUTPut:SYNC OFFON disables or enables output from the SYNC terminal.

Parameters OFF disables the "Sync" output at the front panel BNC connector (see comment below about output level when disabled).

ON enables the "Sync" output. The default is “ON”.

The SYNC output mode is stored in volatile memory.

Comments • The output level on the SYNC terminal is indeterminate (it might be a TTL “high” or a TTL “low”) when the sync signal is disabled.

•*RST Condition: "ON"

:SYNC?

OUTPut:SYNC? queries the state of the SYNC terminal. Returns “0” (OFF) or “1” (ON).

:TRIGger:IMMediate

OUTPut:TRIGger:IMMediate outputs a TTL positive-going pulse from the front-panel Ext Trig terminal IMMEDIATELY regardless of the present setting of the OUTP:TRIG:STAT command. IF OUTP:TTLT<n>:STATE is ON, that VXIbus TTLTRG line will output a negative-going pulse.

Comments • You use this command to issue an immediate external trigger for synchronizing phase-lock signals using the Ext Trig terminal or VXIbus TTLTRG lines.

:TRIGger:STATe

OUTPut:TRIGger:STATe OFFON This command performs no operation. It is included for compatibility with the Agilent 33120A Function Generator.

:TRIGger:STATe?

OUTPut:TRIGger:STATe? This command performs no operation. It is included for compatibility with the Agilent 33120A Function Generator.

:TTLTrg<n>[:STATe]

OUTPut:TTLTrg<n>[:STATe] ONOFF enables or disables the function generator from sourcing a trigger signal on a VXIbus TTLTRG line (value of <n> selects the line and can range from 0 through 7). The default setting is disabled (OFF). The setting is stored in volatile memory.
