Two Port Insertion Loss
Measuring Two Port Insertion Loss for Spectrum Analyzer,
Channel Scanner, 1xEV-DO Analyzer, CDMA Analyzer, and
Signal Generator (RF In Loss and RF Out Loss)
When you perform spectrum analysis, TX analysis (CDMA, W-CDMA, 1xEVDO,
and so forth), or measure signal generator outputs, you can measure accurately, and
store, the device loss values. These RF In and RF Out Loss values can be used later
in the measurements. This gives greater accuracy in your measurement results as
you can use these stored RF In and RF Out values instead of entering approximate
values.
Step Notes
1 Connect the cable or device. Connect the 3 meter (10 ft) cable, high power
attenuator, and other 60 cm (2 ft) cable (not
used for normalization) between the two 10 dB
pads that were used for normalization.
