Keep in mind that the total time for the reference receiver calibration (step 1) is approx-
imately given as the product of "Sweep Points" and "Meas. Delay Time". At the lowest
power range of the PMx, the reference receiver calibration can easily take several tens
of minutes, as the response time is in the range of several tens of seconds.
Power sensors of the R&S
NRP-Z family, on the other hand, can be queried for the
state of the current measurement. The analyzer automatically waits until the power
value is stable and "ready for reading" (
→
system-determined response time). For
these power meters, a positive "Meas. Delay Time" only makes sense, if an
additional
delay on top of the system-determined response time is required.
Load from VNA
Loads the active channel's start frequency, stop frequency, number of sweep points
and measurement delay from the analyzer and applies them as "Frequency From",
"Frequency To", "Sweep Points" (see
"Frequency From/To and Sweep Points"
on page 25, respectively. Note that this only
works if the active VNA channel is configured for a frequency sweep.
Load Default
Resets all leveling settings to their (frequency converter type-specific) defaults.

Calibration Commands
The buttons on the right hand side of the main window execute the leveling procedure
as described in
Chapter 2, "Leveling Procedure"
on page 6. The leveling can be per-
formed step-by-step ("Manual Calibration") or in one go ("Automatic Calibration").
