Noise Figure Measurement Personality and Option H26
This section provides nominal performance information for the PSA series, Option 219,
Noise Figure Measurement as it relates to the Option H26, High Band Preamp.
CAUTION Excessive Relay Switch wear can occur if the instrument is sweeping
from a start frequency of 3.05 GHz and below to above 3.05 GHz. This
is different than when operating in the SA Mode.
You need the following equipment to use this personality/hardware combination.
NOTE The Noise Figure Measurement personality (Option 219) requires
Revision “b” or later of the Front End Driver assembly. This supplies
the +28 V output (labelled “NOISE SOURCE DRIVE OUT +28 V
(PULSED)” on the rear panel), which is needed to drive the noise
source. To see which version is installed on your PSA, press System,
Show Hdwr. If you have an earlier revision than Revision “b,” contact
your Agilent Technologies representative.
