Have PN2060A phase noise analyser, will measure
Have PN2060A phase noise analyser, will measure! This post is for measurements of different TCXOs I have on hand. The measurements are not too exact as I am not set up for precise measurements. However, the two reference TCXOs run on batteries and all the equipment is warmed up for at least 30 minutes. If I see an odd result I repeat it. Before I start, the performance of the latest R&S FSPN phase noise analyser for comparison. Its noise floor is a bit lower. The plot is processed data with spikes removed, among other things, so comparable to the PN2060A data after Matlab processing. One thing R&S stress is improved DC supplies, showing the sensitivity to power supply noise. Hence, running everything on batteries is a good idea as a cheap alternative. The floor of the instrument is about 180 dBC/Hz. This is just above the noise from a resistor os about 184 dBC/Hz, the absolute floor. Keysight MXA N9020A Vector signal analyser.
