Remote Interface Reference 4
Keysight 33210A User’s Guide 235
–When the Bus (software) source is selected, the function generator outputs
one burst each time a bus trigger command is received. To trigger the function
generator from the remote interface (GPIB, USB, or LAN), send the *TRG
(trigger) command. The front-panel key is illuminated when the function
generator is waiting for a bus trigger.
–When the External or Bus trigger source is selected, the burst count and burst
phase remain in effect but the burst period is ignored.
–The APPLy command automatically sets the trigger source to Immediate
(equivalent to TRIG:SOUR IMM command).
– To ensure synchronization when the Bus source is selected, send the *WAI
(wait) command. When the *WAI command is executed, the function
generator waits for all pending operations to complete before executing any
additional commands. For example, the following command string guarantees
that the first trigger is accepted and the operation is executed before the
second trigger is recognized.
TRIG:SOUR BUS;*TRG;*WAI;*TRG;*WAI
– You can use the *OPC? (operation complete query) command or the *OPC
(operation complete) command to signal when the burst is complete. The
*OPC? command returns “1” to the output buffer when
the burst is complete.
The
*OPC
command sets the “Operation Complete
” bit (bit 0) in the Standard
Event register when the burst is complete.
TRIGger:SLOPe {POSitive|NEGative}
TRIGger:SLOPe?
Select whether the function generator uses the rising edge or falling edge of the
trigger signal on the rear-panel Trig In connector for an externally-triggered burst.
The default is POS (rising edge). The :SLOP? query returns “POS” or “NEG”.
