The ESU is the replacement for the ESIB.

Features[edit]
The ESU has a new feature compared 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 method 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.
Firmware[edit]
The latests known firmware (at 2014, June) is: 4.73 SP1. The release notes of that firmware version can be found here
Time domain scan[edit]
Using a very small RBW on higher frequencies in combination with the Time domain scan will result in big files. The step size or number of points is determined by the RBW. The stepsize is always 1/4 of the RBW, and can not be changed. For a RBW of 9 KHz the step size is 2.25 KHz.
Possible solutions are:
- Larger RBW at higher frequencies.
- Using the receiver mode instead of the Time domain.
- Using the analyser mode instead of the Time domain.
Preset configuration[edit]
The preset configuration of the Rohde & Schwarz can be modified. Selecting the default factory preset mode is explained on the Rohde & Schwarz Preset configuration.
