This final article focuses on specifications that apply to RF signal analyzers. Because there are two major types of RF signal analyzers, vector signal analyzers and spectrum analyzers, we first explain the distinctions between both instruments. Then we provide an introduction to specifications that apply specifically to spectrum measurements that include dynamic range, averaging methods, and displayed average noise floor. Catch up on part 1 and part 2 first.
The DCR-8 is an eight port switch remotely controllable via USB or Ethernet. The switch automatically recognizes either type of control connection. Control microwave signals with a laptop or PC using the USB interface or remotely over the internet.
JFW recently introduced the 50FHIE series of fixed attenuators. The 50FHIE is capable of handling 1000 watts of RF power with no liquid cooling or forced-air requirements. Operating frequency range is DC to 3 GHz and the attenuators are available with N connectors in values of 10 dB, 20 dB, or 30 dB.
