Stat. Gating:
Selects Freerun or Marker gating for statistical acquisition. If
Freerun is selected, then all the samples are acquired without regard to
sweep acquisition. If Markers are selected, then only samples within the time
marker interval on the Pulse mode triggered sweep will be included in the
statistical sample population.
Term Count:
Sets the terminal sample count for the CCDF acquisition.
Term Time:
Sets the terminal running time for the CCDF acquisition.
Term Action:
Select the action to take when either the terminal count is
reached or terminal time has elapsed. Selecting Decimate will divide all
sample bins by 2 and continue. The total sample count will be halved each
time a decimation occurs. Selecting Restart clears the statistical sample population and starts a new
one. Selecting Stop will stop accumulating samples and hold the result.
