5.2.10 External Control Signals
5-55
Tp: Period setting time
Th: Hold setting time
Tp (ext): TRIGGER IN signal period time
Th (ext): TRIGGER IN signal Hold-time
(Time from inputting Sweep start trigger to generating start source value)
Thp (ext): Time from inputting Sweep start trigger to inputting a trigger for the next step source value
Top: Time from specifying Operate to inputting TRIGGER IN signal
*1: The approx. value calculating from Number of steps × 0.5 ms is added in the Sweep
source mode.
Tp (ext) min: The operational minimum period of TRIGGER IN signal
Conditions:
Source range; fixed, Measurement range; fixed, Trigger mode; HOLD, Integration
time; 100 μs, Auto Zero; OFF, Measurement delay;100 μs, Source delay; 30 μs,
Pulse width; 500 μs, at high-speed burst operational status in BURST mode (*2)
*2: High-speed-burst operational status
High-speed burst operational status starts when TRIGGER IN signal is input with
the conditions, Measurement range; fixed, SWP Range; fixed, Trigger mode;
HOLD, and Memory mode; BURST. And it is as follows:
• indicator is always displayed rotating.
• Pressing TRG key and executing the *TRG command are ignored until the
source measurement condition is changed or Suspend or Standby is specified.
• When TpALM turns on, this function stops and the step time becomes the same
as NORMAL and OFF.
