:INITiate Subsystem
This subsystem controls the initiation of a measurement.
COMMAND :INITiate:CONTinuous . . . <Boolean>
Sets or queries the state of continuously initiated measurements.
When CONTinuous is set to OFF, no measurements are made until
CONTinuous is set to ON or :INITiate[:IMMediate] is received.
Once CONTinuous is set to ON, a new measurement is initiated.
On the completion of each measurement, with CONTinuous ON,
another measurement immediately commences.
QUERY RESPONSE • Single ASCII-encoded byte, 0 or 1.
• A value of 0 indicates OFF; a value of 1 indicates ON.
COMMENTS • *RST: OFF
• The commencement of the first measurement due to setting
:INITiate:CONTinuous to ON sets the Pending Operation Flag to true.
The Pending Operation Flag is set false by aborting a measurement,
or by the completion of the last measurement after :INITiate:
CONTinuous is set OFF.
• With the measurements being made continuously, the :ABORt
command aborts the current measurement in progress, however,
the value of :INITiate:CONTinuous is unaffected. If CONTinuous was
set to ON prior to receiving :ABORt, it remains ON and a new
measurement begins.
• When a single measurement is in progress (:INIT:CONT is OFF):
– Error -213 (Init ignored) is generated and the state of INIT:CONT
is unaffected by :INIT:CONT ON.
– Error -210 (Trigger error) is generated by INIT:CONT OFF.
NOTE The Counter powers up with :INIT:CONT set to ON, but *RST sets
:INIT:CONT to OFF.
