4.3.6.1 Measuring a basic signal
We will start out by measuring a simple sinus wave, using the internal calibration signal
as the input.
To display the internal 50 MHz calibration signal
1. Press the [Preset] key to start out in a defined instrument configuration.
2. Press
3. Press the [Setup] key.
4. Tap the "Service + Support" softkey.
5. Tap the "Calibration Signal" tab.
6. Tap the "Calibration Frequency RF" option. Leave the frequency at the default
50 MHz.
7. Close the dialog box.
The calibration signal is now sent to the RF input of the R&S ZNL/ZNLE. By
default, a continuous frequency sweep is performed, so that the spectrum of the
calibration signal is now displayed in the standard level versus frequency diagram.

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.
