I'm trying to take a simple measurement of ~2.4 GHz (WiFi land) with an RF spectrum analyzer (Tektronix RSA607A) but have so far been unsuccessful. On the
RF In port I have an N-BNC adapter connected to a meter-long BNC cable, which is connected to a BNC-SMA adapter and WiFi antenna. All items in the chain are spec'd at \$50 \Omega\$.
All I am able to measure, however, is noise. I tried using several different cables, reattaching all connections, and even plugging the whole shebang into a Tektronix MSO3054's RF port. I 'know' the spectrum analyzer is working -- I plugged a waveform generator into
RF In by way of a BNC cable and said N-BNC adapter, and the analyzer successfully measured a 1 MHz sine wave.
I'm sure it's something trivial, but we don't have any RF-experience persons around to consult. Does this setup appear obviously incorrect somewhere?
