Invert
Spectrum
On
=Select On if the modulation scheme that you selected requires it.
Off
=Default.
NOTE:
If the desired transmit data spectrum is not inverted, then you should set either the
Modulator invert Spectrum or Demodulator Invert Spectrum to
On
; otherwise, you should set
both to
Off
. This is required because of the high-side LO in the down-converter receiver
inverting the spectrum.
PRBS
On
=Generate a Pseudo Random Bit Sequence (PRBS) for a system test.
Off
=Default.
Sys BW
Displays the system’s maximum capacity (bandwidth) in MHz.
Utilization
Displays the percentage of utilization. This value updates dynamically, so you can change the
values on this screen to optimize system use. See
Determining Overall System Capacity Versus Bandwidth
3.4.4 Setup–Demodulator Screen
NOTE
:
The Demodulator screen should match the settings on the Modulator screen.
Also, when you select Ethernet, you should select it on Core Channel 1.
