Potential Problems During Boot Process
Signal Level Verification
Frequencies Less Than 3.6 GHz
The basic functionality of the instrument below 3.6 GHz can be quickly verified
with the use of the internal 50 MHz calibrator signal. However, if there are
suspected problems at other frequencies an external signal generator will also
be needed:
1. Switch the instrument into the Spectrum Analyzer mode by pressing
Mode, Spectrum Analyzer.
2. Turn on the internal 50 MHz Calibrator signal by pressing Input / Output,
RF Calibrator, 50 MHz.
3. Tune the instrument to 50 MHz with a span of 10 MHz by pressing Freq,
50 MHz, Span, 10 MHz.
4. Place the marker on the peak of the calibrator signal by pressing Peak
Search.
5. Verify that the on screen of the 50 MHz Calibrator signal is −25 dBm
(+/-2 dB), as shown in Figure 2-10.
