Error summary (formats other than FSK)
Measured rms and peak Error vector magnitude, magnitude error, phase
values of the following: error, frequency error (carrier offset frequency),
I-Q offset amplitude droop (PSK and MSK formats),
SNR (8/16VSB and QAM formats), quadrature
error, gain imbalance
For VSB formats, VSB pilot levels is shown
in dB relative to nominal. SNR is calculated
from the real part of the error vector only.
For DVB formats, EVM is calculated without
removing IQ offset.
Error summary (FSK)
Measured rms and peak values of the following: FSK error, magnitude error, carrier offset frequency,
deviation
Detected bits (symbol table)
Binary bits are displayed and grouped by
symbols. Multiple pages can be scrolled for
viewing large data blocks. Symbol marker
(current symbol shown as inverse video) is
coupled to measurement trace displays to
identify states with corresponding bits. For
formats other than DVBQAM and MSK, bits
are user-definable for absolute states or
differential transitions.
Note: Synchronization words are required to
resolve carrier phase ambiguity in non-differential
modulation formats.
