6240B DC Voltage Current Source/Monitor Operation Manual
5.2.2 Operations in Pulse Source Mode
5-11
a. When the trigger mode is AUTO:
• The measurement and the pulse cycle repeat at intervals of the specified period time.
• If the measurement does not finish in the specified period, the pulse width does not change but
the pulse cycle is extended and the TpALM indicator goes ON.
• If the source value or the base value is changed during pulse generation, the pulse source oper-
ation (including COMPLETE OUT signal output) stops and restarts with the new source value
or base value.
b. When the trigger mode is HOLD:
• The measurement starts when the measurement delay time has passed after trigger input.
• Trigger input during measurement is ignored.
• If a trigger is input during range change processing, pulse generation starts when the range
change processing is completed.
c. When setting to Operate or changing the range
• Pulse generation starts when the Operate processing time has passed after setting to Operate.
• If the source change entails the range change, the base value and pulse value are set in the same
range.
d. In Standby or Suspended status:
• The measurement is not executed in Standby or Suspend status.
