:INITiate[:IMMediate]
This event command causes the instrument to initiate either a single measurement
or a block of measurements.
When
:TRIG:COUN:AUTO is OFF, or
:CALC3:AVER[:STAT] is OFF, or
[:SENS]:FUNC[:ON] is any Voltage Peaks function,
then :INIT[:IMM] initiates a single measurement.
When
:TRIG:COUN:AUTO is ON, and
:CALC3:AVER[:STAT] is ON, and
[:SENS]:FUNC[:ON] is not a Voltage Peak function,
then :INIT[:IMM] initiates a complete block of measurements. See
:TRIG:COUN:AUTO for specifics.
• When :TRIG:COUN:AUTO is ON and :CAL3:AVER[:STAT] is ON, the
Comments
Counter clears the statistics results and the statistics current count on
:INIT[:IMM].
• If the instrument is already in the process of making a measurement or if
INITiate:CONTinuous is set to ON, an :IMMediate command has no affect,
and an error -213 (Init ignored) is generated.
• When :CALC2:LIM:CLE:AUTO is ON, the Counter performs the following
whenever the :INIT[:IMM] command is sent:
– invalidates the limit data,
– clears :CALC2:LIM:FAIL, :CALC2:LIM:FCOunt, and
:CALC2:LIM:PCOunt information,
– turns off the front-panel display's Limit annunciator, and
– sets the Limit-Detect output to the in-limit voltage level.
• This command is an overlapped command (se e IEEE 488.2, Section 12).
Beginning a measurement or block of measurements with an
:INITiate[:IMMediate] sets the Pending Operation Flag to true. Completing the
measurement or block of measurements (normally or by aborting) sets Pending
Operation Flag to false.
