Absolute measurements are measurements of the 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 the input of one receiver.
The 1-port Analyzer has two independent receivers A and R:
•The R is reference signal receiver.
•The A is test signal receiver.
A measured absolute parameter is set for each trace. The trace to which the function is applied must be preselected as active (See Active Trace Selection).
To set the measured parameter, use the following softkey Trace > Measurement. Then select the required parameter: •Abs A is test signal receiver. •Abs R is reference signal receiver.

In absolute measurement mode, dBm measurement units are used for logarithmic magnitude format, and W measurement units are used in linear magnitude format. Other formats are not applicable to absolute measurements. |
