3.4.2.1 RRC Correlated
Window #1
Shows the cross-correlation between the measured UWB pulse and a root raised
cosine (RRC) pulse.
3.4.2.2 Transmit Mask
Window #2
Shows the spectrum of the signal with limit lines as defined by the standard (0 dBr is
set to the maximum value within |f| ≤ 0.65 / Tp).
This trace is calculated from the data in the "Raw Main Time" on page 437 trace and
is computed by averaging multiple spectra to simulate a video bandwidth ≤ 1 kHz: A
radio frequency measurement (one kHz = one thousand cycles per second). The
window used in computing the spectra is the Gaussian Top window.
3.4.2.3 Spectrum
Window #3
Shows the FFT of the Raw Main Time waveform.
3.4.2.4 Raw Main Time
Window #4
Also known as RF Envelope, this is the envelope of the captured raw data. This data
is unprocessed and includes additional points acquired for settling of the filters
involved in subsequent processing, such as the demodulation filtering.
