Meas
Provides the digital demodulation measurement function.
Digital Demod
The digital demodulation measurement can be widely used to analyze and measure
various vector modulation formats in frequency domain, time domain and
modulation domain. You can view the pre-demod time and spectrum display,
demodulated signal, reconstructed reference signal, recovered symbols, and various
error traces and summaries. After selecting Digital Demod, press Meas Setup to
set the corresponding parameters of the digital demodulation.
BER Test
Press this key to enable the bit error rate test function. The instrument compares the
current measurement signal with the already known reference signal to obtain the
bit error rate.
The measurement results are displayed in the user interface, as shown
in the figure below

Note: Before performing the BER test, load the BER test file (.xml) first. For how to
load the file, refer to "Known Data" section.
