Hi,
I would like to generate a test DVB-S or DVB-S2 signal (QPSK, 8PSK, 16APSK, 16QAM) in the L-Band (950 - 1950Mhz) then send it through my satellite communications equipment (Block Up Converter, cables, variable phase combiner, wave guides, etc.) and then compare the signal coming out of the rf sample port (Ku-Band 12-14Ghz) of the amplifier to the original signal. The bandwidth is dependent on the symbol rate and should be less than 40Mhz and is typically 36Mhz. What device(s) would I need to conduct such a test?
Thank you,
-dave

Depending on you performance requirements, either of these instruments should fit your needs.
