5.2.2 Pulse Source Mode Operation
5-11
a. Trigger Mode is AUTO
• The measurement and pulse period are repeated in the specified length of period.
• If the measurement does not finish in the specified period, the pulse width does not change but
the pulse period is extended and TpALM indicator illuminates.
• If a source or base value during pulse generation is changed, it stops pulse generation and gen-
erates a new pulse with a new base value and source value.
b. Trigger Mode is HOLD
• Measurement starts after the time length from trigger input to the measurement delay time has
passed.
• It ignores the trigger input during the period time.
• If trigger is input during range change processing, pulse is generated after range change process-
ing is completed.
c. Pulse source operation after Operate and changing range
• If it is Operate, pulse generation starts after Operate is processed.
• If the source-change entails the range-change, base and pulse values are set at the same range.
d. Standby or Suspended status
• During Standby or Suspended, it does not measure.
