Chapter 4 Remote Interface Reference
Burst Mode Commands
4
• 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”.
