From top to bottom, the screen consists of the following elements.
Calibration Sweep Diagram
The calibration sweep diagram in the upper part of the screen shows the progress of the
calibration and the accuracy of a completed calibration ("Verification"). The diagram is
scaled in "dB Mag" format.
The diagram title indicates the ongoing calibration type and reading. The traces in the
diagram vary according to the calibration stage.
While no calibration is performed, or during a source power calibration ("Power"), the
following traces are displayed:
●
A limit line (double horizontal) represents the target power of the source power cali-
bration ("Cal Power").
●
"Pmtr<n>" shows the reading of the power meter Pmtr <n> in use. This trace is only
shown during the first calibration sweeps; the following sweeps are based on the
reference receiver result.
●
"a<m>" shows the source power reading of the analyzer (wave quantity, reference
receiver) at the calibrated source port P<m>.
After successful power calibration the trace a<m> should be close to the cal power.
During a measurement receiver calibration ("Meas. Receiver"), the following traces are
displayed:
●
The trace b<n> shows the current power reading of the analyzer at the calibrated
receive port P<n>.
●
The trace a<m> shows the (previously calibrated) power at the calibrated reference
plane (source port P<m>).
