64 Digitizer Command Reference
The INITiate subsystem controls the initiation of the trigger system and prepares the
Digitizer to take voltage measurements. Once a trigger is received from the
programmed source (TRIGger:SOURce command), measurements begin on all
channels. Normally, all measurement setup (setting measurement ranges, sample
count and trigger sources, etc.) should be done before this command is sent. Sending
this command will cause the Digitizer to begin the measurement process.

:CONTinuous?
INITiate[:IMMediate] initiates the trigger system and prepares the Digitizer to take
voltage measurements. After initiation, the Digitizer enters the wait-for-trigger state
and begins taking pretrigger readings until the pretrigger count is met (if there is a
pretrigger count set). All incoming triggers are ignored until the pretrigger count is
met. Pretrigger readings continue until a trigger arrives. The first trigger received
after the pretrigger readings have been acquired is the one accepted and it advances
the digitizer to the wait-for-sample state which is where readings are actually taken.
When the number of readings specified by the TRIGger:COUNt and
SAMPle:COUNt have been taken, the trigger system returns to the idle state and
digitizer stops measuring.

INITiate:CONTinuous ON | 1 | OFF | 0 is used to either start or stop a continuous
measurement. The ON (1) setting will start a measurement with an infinite sample
count. After initiation, the Digitizer enters the wait-for-trigger state and begins
taking pretrigger readings until the pretrigger count is met (if there is a pretrigger
count set). All incoming triggers are ignored until the pretrigger count is met.
Pretrigger readings continue until a trigger arrives. The first trigger received after
the pretrigger readings have been acquired is the one accepted and it advances the
digitizer to the wait-for-sample state which is where readings are actually taken. The
incoming trigger advances the Digitizer to the wait-for-sample state which is where
readings are actually taken. The instrument will continuously sample until one of
the following three things occurs:
1. The measurement is stopped by the ABORt command.
2. The measurement is stopped by executing INITiate:CONTinuous OFF.
