Timing
The pulsed sweep configuration menu contains no timing control, all single pulsed sweep timing
is based upon the settling/ measure delay, pulsed sweep measurement periods (sweep level
measurement period and pulse steady level measurement period) and the measurement count.
The sweep level measurement period and pulse steady level measurement period are separated
to allow the sweep and steady periods to be completely independent. In situations where
temperature may be an issue the pulse steady measurement period may be extended
significantly to allow time for the DUT to cool sufficiently. The measure delay shown in the
following diagram shows a user defined measure delay, alternatively an automatic settling delay
can be selected, see ‘
’ for more details.
The time it takes to complete one single sweep can be calculated by = (Number of Points x
((Settling Delay x 2) + (Sweep Measurement Period X Measurement Count) + (Pulse Steady Level
Measurement Period))).
NOTE
Only one measurement is made at each pulsed sweep steady level, regardless of the
measurement count setting. When calculating pulse sweep timing take note that there is a
settling time delay for both the sweep and steady level, however one delay setting covers both.
