INITiate[:IMMediate]
The number of measurement cycles is restricted.
If TRIGger:COUNt 1 is set, the command starts a single measurement cycle that
renders one result. Every time you send this command, a new measurement cycle
is started.
Otherwise, as many measurement cycles are performed as determined by the trig-
ger count.
9.5.2.3 Trigger sources
The possible trigger conditions and the execution of a trigger depend on the selected
trigger mode and trigger source.
If the signal power exceeds or falls below a reference level set by the trigger level, the
measurement is started after the defined delay time. Waiting for a trigger event can be
skipped.
Trigger source Description Remote commands to initiate the measurement
"Hold" Triggered by the remote command. TRIGger:IMMediate
"Immediate" Measures immediately, does not wait for trigger
condition.
-
"Internal" Uses the input signal as trigger signal. TRIGger:IMMediate
"External 1" Uses the digital input signal supplied using a dif-
ferential pair in the 8-pin sensor cable.
TRIGger:IMMediate
"External 2" Uses the digital input signal supplied at the SMB
connector.
TRIGger:IMMediate
"Bus" Triggered by the remote command. *TRG
TRIGger:IMMediate
9.5.2.4 Dropout time
The dropout time is useful when dealing with signals with several active slots, for
example GSM signals, see Figure 9-1. When measuring in sync with the signal, a trig-
ger event is to be produced at A, but not at B or C.
