I need to analyze data from DVB-S receiver. Eye diagrams etc. Having problem getting my ADC-200 to do this. Which new model better?

Hello Rick,

What is the output signal speed you need to measure?

Essentially 25Mbit/sec. The data is QPSK which demodulates into two data streams. The difficulty comes because the QPSK constellation is not stabilised. Basically, I need better triggering and rise/fall times. Can I display sample points as dots instead of joined-up lines? Then the 10Gsample feature on later models would give good eye diagrams at this and higher data rates.

Hello,

Then please consider our 3205 or 3206. These instruments would offer high sampling rates and deep memory. Allowing you to capture fast sampling data streams over longer periods.

Further information can be found here:
