3GPP EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. Minimization supported for uplink and downlink: amplitude, frequency, and timing. For uplink, IQ Offset EVM Minimization is also supported.
Definable shared channel and control channel/signal power boosts
Adjustable symbol FFT Fast Fourier Transform: A mathematical operation performed on a time-domain signal to yield the individual spectral components that constitute the signal. See Spectrum. locations and EVM window length for OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. symbols

Averaging available for a variety of trace data and most numeric error summary, frame summary, and MIMO info table data:
- rms (video) - computes an rms average from the specified number of measurement sweeps
- rms (video) exponential - similar to rms (video) except that averaging continues past the average count with an exponential weighting
- continuous peak hold - holds the peak value of all the sweeps
Support for Direct Calculation for Time Domain Input mode.
