Channel impulse response (SFN
echo pattern)
(a) Selectable center and time/div
(b) Scale type by time or distance
(c) Results sorted by amplitude or time/distance
(d) Default echo search limit -35 dB and adjustable
(e) Adjustable FFT start position (0/8 to 8/8 GI), and MER metric displayed on the top of the view can be used as the
criteria to tune the FFT window
(f) Support pre-echo, post-echo, 0-dB echo, and out-of-GI echo scenarios
1.â ML (mixer level) is RF input power minus attenuation
2.â The accuracy specification applies at the EVM = 1%
3.â tfa = transmitter frequency à frequency reference accuracy
