STEP
This function is used to set the sweep time while in stepped sweep mode.
SWPTIME
The stepped sweep time can only be changed while the sweeper is in stepped
sweep mode. The front panel
m
key which is normally used to set sweep
time while in analog sweep mode, will display the dwell time if pressed while
in stepped sweep mode. The stepped sweep time is coupled with Dwell Time
and Points by the equation:
Step sweep time =
(DwellTime)
* (Points)
Note that the equation does not include frequency switching
time.
As stepped sweep time is adjusted, dwell time will be adjusted
proportionately. At factory preset, the dwell time is set to its minimum
setting of 1 ms. Therefore, the stepped sweep time cannot be decreased from
its factory preset value unless the number of points is decreased.
NOTE
If stepped sweep time is adjusted to an invalid sweep time, the stepped sweep time value will snap to
the nearest legal value and instrument error -222 (limit
error1
may occur.
