Features[edit]
The ESU has a new feature compaired to the ESIB en the ESPI. LAN is standard. It has what is called time domain scan. which is FFT functionality to get spectrum. This FFT option is an additional option that you need to pay for. note that at this moment the FFT methode is not a valid way of getting the spectrum compliant. but when using is a pre-compliant way of getting the frequencies of the peaks it is. known special limitations are:
- min span in time domain scan is 10 times the RBW
- pre amplifier, can only be use from 1 khz in receiver mode.
- Pre amplifier, can only be used up to 3.6 GHz. for the full range you need a special option.
