RF Frequency Sweep (cont'd)
3-58
Example for Calculation #4 (Stepped Frequency Sweep)
In an 86 42B, set a stepped frequency sweep from 100 to 500 MHz with a sweep step size
of 8 MHz with Special Function 219 (Re-Enable Scttling).
First select Instrumcn t Preset:
Cf]\JSTFCP-HESeTJ
Calculate the required sweep time setting for an 8 MHz step size using calculation #4:
Ensure that an integer results when the frequency span of 400 MHz is divided by the
step siz.e of 8 MHz.
400 MHz
8 MHz
= 50
Maximum step size is equal to the maximum of I Hz or:
1100 000 000 Hz - 500 000 000 Hz 1= 400 000 000 Hz or 400 MHz
[INTEGEROF(~~~ -l)J
Since 400 MHz is greater than 1 Hz, the maximum step size is 400 MHz.
Minimum step size is equal to the maximum of I Hz or:
1100 000 000 Hz - 500 000 000 Hz I
1023 = 391 006 Hz or 0.391006 MHz
Since 0.391006 MHz is greater than I Hz, the minimum step size is 0.391006 MHz.
Therefore, it should be possible to select an 8 MHz step size since that value is between
the minimum value (0 391006 Hz) and maximum value (400 MHz).
