5.3.2. Frequency Domain Calibration

The purpose of this step is to calibrate out the RF effects (i.e. mismatch, loss or delay) of
RF cables and test fixtures. Full calibration is performed by using the 4-port ECal Module
at the end of RF cables connected to the ENA test ports. The fixture effect will be
eliminated by de-embedding S-parameters (*.s4p or .s2p) of the fixture. The S-parameter
data is provided by fixture vendors.
The calibration is applied for frequency-domain measurements in channel 2.
5.3.2.1.
Calibration for the frequency-domain measurement is performed by selecting the ENA's
soft key. The 4-port ECal Module (i.e. N4431B) connected to the E5071C is necessary for
the calibration procedure.
