Channel Response Normalization Mode (Channel Sounding)
affects the Y-axis values of the Frequency Response and Impulse Response traces.
-
- Impulse response - peak at t=0 reflects the total signal power (dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer) when signal contains a single path and no noise
- Frequency response - scaling matches Spectrum trace
-
- Impulse response - trace is normalized so that peak is at 0 dB.
-
Frequency response - trace is normalized so that a perfectly flat channel will be at 0 dB (normalized by main peak power)
You can copy this trace into a data register to use with Fixed Equalization () to correct for the effects of a channel. Note that the VSA Span must be less than or equal to the symbol rate to get reasonable results.
