Therefore the Cable TV Measurements option introduces the concept of the so–called modulation standard. Modulation standards describe the signal characteristics, or physical layer, transmitted via a channel.

    R&S FSL SCPI Command Structure and Syntax SCPI Command Structure and Syntax SCPI (Standard Commands for Programmable Instruments) describes a standard command set for programming instruments, irrespective of the type of instrument or manufacturer. The goal of the SCPI consortium is to standardize the device–specific commands to a large extent. For this purpose, a model was developed which defines the same functions inside a device or for different devices.

The measurement itself is performed in zero span on the center frequencies of the individual channels. The command automatically switches to zero span and back. Depending on the selected mobile radio standard, weighting filters with cos characteristic or very steep–sided channel filters are used for band limitation.
