4.7.2 S-Parameter Setting
A measured parameter (S11, S21, S12 , S
22) is set for each trace. Before you select the
measured parameter, first activate the trace.
To set the measured parameter, use the following softkey:
Measurement
Then select the required parameter by the corresponding
softkey.
4.7.3 Absolute Measurements
The absolute measurement is the measurement of absolute power of a signal at a
receiver input. Unlike relative measurements of S-parameters, which represent a relation
between the signals at inputs of two receivers, absolute measurements determine the
signal power at input of one receiver. A 2-port Analyzer has four independent receivers:
A, B, R1, R2 (See figure 4.11).
