Commands Reference
:INITiate Subsystem
– reports the negative status condition (NOT Computing Statistics)
to bit 8 of Operation Status Register.
• When :CALC2:LIM:CLE:AUTO is ON, the Counter performs the following
whenever the :INIT:CONT ON 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.
• When [:SENS]:EVEN:LEV[:ABS]:AUTO is ON and channel 1 is a
measurement channel, the Counter performs an auto-trigger on channel 1
whenever the :INIT:CONT ON command is executed, and also at the beginning
of each measurement cycle while :INIT:CONT is ON.
• The state of :TRIG:COUN:AUTO has no affect on the operation of
:INIT:CONT ON.
• :INIT:CONT ON operates as if :TRIG:COUN was 1.
• 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 of 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 shall
abort 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 measurem ent 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 that the Counter powers up with :INIT:CONT set to ON, but *RST sets
:INIT:CONT to OFF.
