Level: - 25 dBm
Procedure on the R&S FSVA/FSV:
1. Set the R&S FSVA/FSV to its default state by pressing the PRESET key.
2. Set the center frequency to 128 MHz and the span to 100 kHz.
3. Switch on the marker by pressing the MKR key.
The marker is positioned on the trace maximum.
4. Set the measured signal frequency and the measured level as reference values.
a) Press the MKR FUNC key
b) Press the "Ref Fixed" softkey.
The position of the marker becomes the reference point. The reference point
level is indicated by a horizontal line, the reference point frequency with a verti-
cal line. At the same time, the delta marker 2 is switched on.
