Press [Amplitude], [Units] and [Volt].
In this case, the unit of the differential marker will automatically change into volt. An easy way to determine
distortion percentage is to change the unit to volt. Move the decimal of the proportion indicated by the differential
marker rights for two places to obtain the distortion percentage. The minimum ratio that can be displayed is 0.01 or
1%.
3) Accurate harmonic measurement
It takes more steps to measure in this method, but since measurement is done with smaller span and resolution
bandwidth for each signal, the signal-to-noise ratio is increased and more accurate measurement result will be
obtained. It will be explained below how to measure the harmonic of 1 GHz signals.
a) Set the output signal of the signal generator:
Set the frequency of the signal generator as 1GHz and power as -10dBm. Connect the output of the signal
generator to the input port of the spectrum analyzer, as shown in Fig. 4-1. Enable the ON state of the radio
frequency.
b) Set the starting frequency and stop frequency of the spectrum analyzer.
Press [Reset] key.
Press [frequency], [Start Freq], 800[MHz], [Stop Freq] and 2.5[GHz].
c) Set the video bandwidth to smooth noise so as to improve the resolution.
Press [Bandwidth], [Video Bandwidth Auto Man] to enable auto off.
Use [↓] key to reduce video bandwidth.
d) Reduce the span by the signal tracking function.
Press [Peak] to activate the signal peak of marker search.
Press [frequency] and [Signal Track Off On].
Press [frequency], [Span] and 100[kHz].
e) Disable signal tracking.
Press [Frequency] and [Signal Track Off On].
f) Move the signal peak to the top division to obtain the highest amplitude measurement accuracy.
Press [Peak] and [Peak Search], and read the peak power.
