4 Measurement Application

This chapter introduces spectrum analyzer's functions and
usage by examples. Detailed contents are as follows:

Measurement of continuous-wave signal

Measurement of signals with close resolution bandwidth
and resolution range
Measurement of signal frequency by frequency counter
Measurement of N dB bandwidth
Measurement of adjacent channel power
Measurement of channel power
Measurement of occupied bandwidth
Measurement of small signal by pre-amplifier
Measurement of harmonic distortion
Measurement of Third-order Intercept Distortion
Measurement of AM modulation signal
4.1 Measurement of Continuous-wave
Signal
One of the most common tasks of spectrum analyzer is to
measure frequency and amplitude of signal. In the following
example, continuous-wave signal (300MHz, -10dBm)
generated by signal generator (Agilent E4421B) as signal to
be measured.
Operation steps:
1. Connect equipment
Connect signal output of signal generator with RF input of
UTS1000 Spectrum Analyzer.
2. Set parameters
1 Reset instrument
- Press PRESET key;
2 Set parameters
- Press FREQ key;
- Press [Center frequency] key, and input 300Mhz;
- Press SPAN key;
- Press [Span] and input 2MHz;
3 Measure frequency and amplitude by using marker
- Press MARKER key;
- Press PEAK key;
