Description
Peak value of the frequency deviation error at the symbol point.
RMS value of the frequency deviation error at the symbol point.
The Peak magnitude difference between the measured signal and the reference signal
magnitude.
The RMS magnitude difference between the measured signal and the reference signal
magnitude.
The frequency difference between the measured carrier frequency of the signal and the
user-selected center frequency of the instrument.
Frequency distance from the center frequency at the symbol point.
This compares the user-entered symbol rate to the instrument calculated symbol rate of
the analyzed signal.
When in Auto-symbol rate, the instrument calculates the symbol rate of the signal and
the instrument calculates the error between the user entered value and the instrument
calculated value.
Description
RMS value of the frequency deviation error at the symbol point.
Frequency difference between averaged signal frequency and the center frequency.
Frequency distance from the center frequency at the symbol point.
Number of symbols in the analysis area.
Description
Positive peak AM value.
Negative peak AM value.
Total AM value, which is equal to the peak-peak AM value divided by 2.
Description
Positive peak frequency deviation.
Negative peak frequency deviation.
RMS value of the frequency deviation.
Peak-to-peak frequency deviation divided by 2.
Peak-to-peak frequency deviation.
