Power sweeps and ALC can only be activated, if leveling data are available (see
Chapter 9.4, "Scalar power calibration and leveling (optional)"
The "Port Settings" dialog (Channel – [Channel Config] key > "Port Config" tab >
"Port Settings ...") shows the frequency and power sweep ranges of all implied
signals, including RF IN, LO IN and IF output. Refer to the R&S
ZNA help system
or user manual for details.
●
After power-up, a warm-up time of one hour is required to ensure accu-
rate measurements.
●
Measurement results can be degraded if the setup is exposed to an
electromagnetic field at the IF frequency (default: 279
MHz).
●
For pulsed signals, the default IF frequency of 279
MHz cannot be used,
because a narrow-band filter is applied at this frequency. Use the "Con-
verter Configuration" dialog to select an IF frequency in the direct path
between 30
kHz and 30
MHz instead (see
●
If a power splitter is used and the phases of S
ij
and S
ji
deviate or drift by
equal magnitude, but opposite sign, check the phase stability of the LO
paths of the converters.
