8712ET/ES and 8714ET/ES Adjustments
RF Network Analyzers B* Amplitude Correction, Adjustment #110
Service Guide 2-21
B* Amplitude Correction, Adjustment #110
In this adjustment, correction data is generated to calibrate the internal broadband
B* channel detector for accuracy and power at 30 MHz.
Required Equipment
NOTE Adjustments 104 and 105 must be completed before performing this
adjustment.
The required equipment for this adjustment varies depending upon whether or not the
analyzer has an internal step attenuator installed (ET model analyzers with option 1E1
and ES model analyzers). If the analyzer has an internal attenuator, then only a type-N
cable is needed to complete the adjustment. If an attenuator is not installed, then a 20 dB
attenuator of the proper impedance will also be required.
If a 75 20 dB attenuator is not readily available for Option 1EC analyzers, you can
substitute two back-to-back minimum loss pads with a 6 dB 50 attenuator inserted in
between (several adapters may also be required).
Warmup Time
Allow the analyzer to warm up for one hour.
Estimated Adjustment Time
This adjustment takes approximately three minutes to perform.
1. These cables are preferred because they have a better match and lower loss, which result
in a better default calibration.
2. This item may not be required; see text below.
