Bucket Width (in Hz) =
so
Bucket Width (in Hz) =
Now we can work out the external source's start frequency using the
following equation:
PSA Start Frequency
-------------------------------------------------------------------------------------------------------------------------------- -
2,850,000,000 +
= ----------------------------------------------------------------------------
1
= 2,849,750,000 =
Finally we can calculate the external source's stop frequency using the
following equation:
PSA Stop Frequency +
-------------------------------------------------------------------------------------------------------------------------------- -
Harmonic Number
3,000,000,000 +
= ---------------------------------------------------------------------------- -
1
= 3,000,250,000 =
So if you specify on your PSA Series analyzer that you want to sweep
from 2.85 GHz to 3.0 GHz using 601 points, the signal source itself will
actually sweep from 2.84975 GHz to 3.00025 GHz.
