I have measured my system in steps:
power send by AWG (PXI 5441): 500 mV toptop
received directly on scope (PXI 5124): 410mV toptop
recieved if fist through downconverter (5600): 66mV toptop
- I rather think i lost a lot of power through this link, Is this correct?
If i now upconvert the signal through the 5610, IF 15MHz, RF 35MHz, awg output still 500mV toptop...
The power measured directly at the scope is: 320mV toptop
If i then again use the Downconverter, the power at the scope is a noisy level of 49 mV toptop..
Now is My question is this normal?
