Figure 4-5: Calibration signal as RF input
Instrument warmup time
Note that the instrument requires an initial warmup time after switching it on. A mes-
sage in the status bar ("Instrument warming up...") indicates that the operating temper-
ature has not yet been reached. Wait until this message is no longer displayed before
you start a measurement.
To optimize the display
To optimize the display for the calibration signal, we will adjust the main measurement
settings.
1. Set the center frequency to the calibration frequency:
a) Tap the "Overview" softkey to display the configuration "Overview".
b) Tap the "Frequency" button.
c) In the "Center" field, enter
64
on the number pad on the front panel.
d) Press the "MHz" key next to the number pad.
2. Reduce the span to 20
MHz:
a) In the "Span" field of the "Frequency" dialog box, enter
20
MHz
.
b) Close the "Frequency" dialog box.
3. Set the reference level to -25
dBm:
a) In the configuration "Overview", tap the "Amplitude" button.
b) In the "Value" field of the "Amplitude" dialog box, enter
-25
dBm
.
The display of the calibration signal is now improved. The maximum at the center
frequency (=calibration frequency) of 64
MHz becomes visible.
