This application note addresses the diverse possibilities of interoperability between Rohde & Schwarz power sensors and Rohde & Schwarz signal generators. All current and many legacy Rohde & Schwarz signal generators offer the capability of directly connecting power sensors. This enables power measurements without the need of a base unit or separate PC to display the readings. Furthermore, sensors can be used for special tasks like filling a user correction table or continuously controlling levels at crucial points in the measurement configuration.

DIRECTV®, a digital TV broadcast system, makes use of transport packets with a length of 130 bytes rather than the more common 188 bytes used in MPEG TS streams. The inputs on the R&S® SFU do not accept transport streams in the DIRECTV® format. This Application Note introduces R&S® DIRECTV tool and explains how it can be used to convert existing 130-byte-based DIRECTV® transport stream content to 188-byte-based ISO 13818-1 streams that are compatible with the R&S® SFU SPI input or the internal R&S® SFU TRP player. This tool is intended for Rohde & Schwarz customers who are licensed to operate an R&S® SFU-K9 DIRECTV coder or R&S® SFU-K108 AMC coder.

The RSIB interface enables the network analyzers of the ZVR family to be controlled by means of Windows applications via DDE. The interface functions are contained in the DLL RSIB.DLL. The other DLL RSDDE.DLL provides functions for the DDE access to the instrument firmware. These functions are used by RSIB.DLL. The interface of these functions greatly corresponds to that of National Instruments for programming the GPIB. The function names are similar to those of the NI library but preceded by RSDLL. The two DLLs are part of the firmware and are updated with the firmware update kits.

The Society of Cable Telecommunications Engineers (SCTE) defined the ANSI/SCTE 40 specification: Digital Cable Network Interface Standard. ANSI/SCTE 40 tests are designed to test conformance of set-top boxes and other cable receiving equipment to ensure that they will operate correctly when installed in a cable system. The tests are a combination of noise (AWGN and phase noise), AM hum, micro-reflections, digital and analog adjacent channels, and other discrete interferences. These impairments are found on most cable systems to some degree. Rohde & Schwarz provides set-top box manufacturers with an easy solution to perform conformance testing in line with ANSI/SCTE 40 by using the R&S®SFU broadcast test system and the R&S®SFE100 broadcast tester. The R&S®SFU is able to perform most of the test procedures in one unit. Furthermore, additional test transmitters allow the simulation of full channel loading. This Application Note explains the specific test requirements, a possible setup, and the configuration using the R&S®SFU/SFE100.
