TRIGger:COUNt {<count>|MIN|MAX|DEF|INFinity}
TRIGger:COUNt? [{MIN|MAX|DEF}]
Selects the number of triggers that are accepted by the instrument before returning to the "idle" trigger
state.
Parameter Typical Return
1 to 1,000,000 (1x10
6
) or continuous (INFinity). Default: 1. (34460A/61A)
1 to 1,000,000,000 (1x10
9
) or continuous (INFinity). Default: 1. (34465A/70A)
+1.00000000E+00
For a continuous
trigger (INFinity),
the query returns
"9.9E37".
Return ten sets of five DC voltage measurements, using a positive-going external trigger to start each meas-
urement set:
CONF:VOLT:DC
SAMP:COUN 5
TRIG:COUN 10
TRIG:SOUR EXT;SLOP POS
READ?
Typical Response: +1.00520000E+01, … (50 measurements)
l You can use the specified trigger count in conjunction with a sample count (SAMPle:COUNt), which
sets the number of samples to be made per trigger. In this case, the number of measurements
returned is the sample count multiplied by the trigger count.
l You can store up to 1,000 measurements in the reading memory of the 34460A, 10,000 meas-
urements on the 34461A, 50,000 measurements on the 34465A/70A (without the MEM option), or
2,000,000 measurements on the 34465A/70A (with the MEM option). If reading memory overflows,
new measurements overwrite the oldest measurements stored; the most recent measurements are
always preserved. No error is generated, but the Reading Mem Ovfl bit (bit 14) is set in the Ques-
tionable Data Register's condition register (see Status System Introduction).
l A variable trigger count is not available from the front panel. If you set the trigger count and then go
to local (front panel), the instrument ignores the trigger count setting; however, when you return to
remote, the trigger count returns to the previous value you selected.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset
(SYSTem:PRESet).
