So I want to buy a spectrum analyzer and I'm going to measure frequency responses up to 150 MHz with it. However, there's an odd situation: analyzer with a tracking generator costs $2500 and the analyzer without one costs $500 and I'm trying to figure out what would be a better option, buying an analyzer with a tracking gen or building a noise source with a zener and a few MMIC amplifiers. Are there any additional challenges and pitfalls with measuring frequency responses using a noise source?
