HP 8642A Operation And Calibration Manual

Model 8642A/B Operation
RF Frequency Sweep (cont'd)
4) Calculate a sweep time setting that could be selected fOl' a desired step size.
4a) You
need to choose the step size so the frequency span divided by the step size is an
integer. You must also ensure that the desired step size is between the maximum and
minimum step size possible.
The maximum step size is equal to the maximum of:
1 Hz
or
I Start Frequency (in Hz) - Stop Frequency (in Hz) I
[

The minimum step size is equal to the maximum of:
1 Hz
or
I Start Frequency (in Hz) - Stop Frequency (in Hz) I
1023
4b) When the sweep step size equals the minimum, usc a sweep time setting (in ms)
equal to or greater than the result of the following calculation.
[(
I Start Frequency (in Hz) - Stop Frequency (in Hz) I) + 11 X Min. Dwell Time (in ms)
Step Size (in Hz)
When the sweep step size is greater than the minimum, use a sweep time setting greater
than or equal to the result of the above calculation, but less than the result of the
following calculation:
[(
I Start Frequency (in Hz) - Stop Frequency (in Hz) I) ] .
+ 2 X Min. Dwell Time (1/1 ms)
Step Size (in Hz)
3-57
