get data faster from FFT Analyzer
Last system tests with user script and FFT analyzer shows that the communication between instruments takes almost 2 seconds for all of the command / response to get the data.
In this measurement configuration, we configure the analzer to measure the magnitude and phase differences between two channels. Then we set some markers, and query for the results. It is too slow. The current implementation of flow control between observation sequence and query FFT Analyzer data "works", but it would require moving extremely slowly through the OTF pattern on sky to achieve sufficient spatial sampling. Therefore, I recommend to change the instrument configuration to pull both channels entire spectrum in one command (if possible), and do the calculations locally in TCS.
The other positive side effect of this config is that we will be able to save .mbfits files as well and do cross-scan pointing corrections measurements with the same hardware.
