I have an arbitrary waveforum generator m8195a from keysight. The data sheet of the device includes a graph for the frequency response, phase noise and a rating for the analog bandwidth (25Ghz). However, it is not indicated, whetther these two parameters (frequency response and phase noise) are for the whole device, or the output amplifier or the output of the device. So I want to know this at first. Moreover, I am interested in knowing how to measure these parameters.
data sheet can be found here:
https://www.keysight.com/de/de/assets/7018-04509/data-sheets/5992-0014.pdfI know from my studies that to measure the frequency response of a circuit (RLC for example) I apply a sweep sin wave to the input and measure the output, then find the ratio of output to input for the bandwidth of interest. I can also use an oscilloscope to do this and use frequency response analysis tool to get the bode plot showing both gain and phase. Is it possible to do the same to the AWG? How?
For phase noise I think I can use a spectrum analyzer to measure it, not sure though
For analog bandwifth I need to find the frequency at which the output voltage drops by 3db, but I have no idea how to do this. Normally I would use a generator to measure the bandwidth of an oscilloscope, by giving a signal as an input to it, then increasing the frequency of the signal on the generator until I see the voltage on the oscilloscope drops by 3db. But I dont know how to do this for an AWG or if its doable.
Any suggestions?
