≤
50 MHz/ms
Sweep time range
30 ms to 99 seconds
Sweep width
Independently selected, 1 kHz (0.1 Hz with Option 11) to full range. Every frequency step in sweep range
is phase-locked.
Accuracy
Same as internal or external 10 MHz time base
Phase-locked

Number of steps: Variable from 1 to 10000
mode
Steps
Step size: 1 kHz (0.1 Hz with Option 11) to the full frequency range of the instrument. (If the step size does
not divide into the selected frequency range, the last step is truncated.)
Dwell time per step
Variable from 1 ms to 99 seconds
Switching time
<15 ms +1 ms/GHz step size or <40 ms, whichever is less (typical max.)
Alternate sweep mode
Sweeps alternately between any two sweep ranges. Each sweep range may be associated with a different power level.
Manual sweep mode
Provides stepped, phase-locked adjustment of frequency between sweep limits. User-selectable number of
steps or step size.
Programmable frequency agility
Under GPIB control, up to 1000 non-sequential frequencies can be stored and then addressed as a
phase-locked step sweep. Data is stored in volatile memory.
Setting
Up to 20 independent, settable markers (F0 to F9 and M0 to M9)
Markers
Video markers
+5 V or –5 V marker output, selectable. AUX I/O connector, rear panel
Intensity markers
Produces an intensified dot on trace, obtained by momentary dwell in RF sweep
