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.
