Your question; Is there any difference between spectrum analyzer and signal analyzer?
If you search the internet for signal analyzer you will get information on spectrum analyzers, signal source analyzers, digital logic analyzers and signal analyzers. All of them test various characteristics of signals such as frequency, phase, phase noise, jitter, modulation, bit streams and timing among others.
Searching on spectrum analyzers will return information on instruments that traditionally show the signals making up a spectrum (fundamental and harmonics as well as spurious outputs). Newer spectrum analyzers with digital IF circuitry also test phase noise, jitter, modulation and demodulation of complex digital signal formats.
So searching for either of the above two instrument types will find instruments capable of testing signals for many different signal characteristics.
