High-speed burst operational status
The High-speed burst operational status starts when the 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:
• The
indicator is always displayed rotating.
• Pressing the TRG key or executing the *TRG command is ignored until the
source measurement condition is changed or Suspend or Standby is specified.
• When TpALM turns on, this operational status stops and the step time becomes
the same as NORMAL and OFF.
