I have an RF signal (5ns pulses every 200ns) coming out from a SMA connector on FPGA board (Spartan 3E Starter Kit). I want to send this signal back to the FPGA using one of the on-board pins.
So, I cut of one end of the SMA to SMA connector cable, hoping to use it for inputing the signal back to FPGA. I tested the waveform on the oscilloscope to find that the output signal was in mV range instead of around 3.3V range (input signal).
So, have I made a mistake? Is there any alternative way which I could follow?
