We stock low frequency units below 3 GHz all the way up to over 40GHz from leading manufacturers including Aeroflex, Anritsu, Keysight/Agilent, Rohde & Schwarz, Stanford Research, Tektronix and other leading brands.
We also carry handheld spectrum analyzers for projects that require portability and accuracy.
In choosing which type spectrum analyzer you need, you need to determine what the upper and lower frequency range is of the signal you will be measuring, as well as its maximum amplitude. Take into consideration the harmonic content as well. Remember, you can’t go wrong if you extend the frequency range you think you need. If the signal amplitude exceeds the input range of the analyzer you can always use external attenuators to reduce the signal level to proper input amplitude.
