In the T&M world, instrument remote control over SNMP (simple network management protocol) lives in the shadow of IEEE/GPIB (general purpose interface bus) based remote control, and only a handful of the T&M equipment available worldwide supports the protocol. It is therefore no surprise that for most T&M engineers familiar with text-based commands over IEEE/GPIB (and lately LAN), the SNMP protocol seems a bit odd and to some even complex at first. The SNMP Toolkit for LabVIEW™ from Viodia™ Inc. can save a considerable amount of development time and furthermore helps programmers to overcome the initial complexities of SNMP programming.

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.

All types of information transmission, including the 'one-way' transmission used in broadcasting, involve feeding a radio frequency (RF) signal to an antenna. This is the essence of the most basic type of transmitter used to emit electromagnetic waves. In the real world, however, a transmitter used for broadcast applications, for example, is much more complex in terms of its functions and design. The different transmitter components must be carefully coordinated. There are many quality parameters that are critical in ensuring that a proper output signal is delivered. Rohde & Schwarz designed the R&S® ETL TV analyzer especially for broadcasting applications. The analyzer allows the measurement of the quality parameters that are relevant in analog and digital broadcasting. This Application Note describes the typical quality measurements performed during compliance testing of TV transmitters. The approach discussed here is based on the example of Rohde & Schwarz terrestrial transmitters for analog TV and DVB-T/H.

Rohde & Schwarz instruments can be shared when users wish to use the same instrument. This can be done quite easily with the LAN interface, which comes as a standard option. Through this interface, Rohde & Schwarz instruments can be connected directly to a network, and users with access to the network can manually operate the instrument from a remote computer. This Application Note lists all instruments that support these features and describes the steps necessary to set up and configure the network connection to operate these instruments remotely.

Play-only devices like CD- or MP3 players cannot be measured as traditional 4-pole devices. Therefore traditional transfer function measurements using the generator part of the audio analyzer are not possible. Those devices are tested with a pre-recorded test signal available as wav or MP3 file. This application note describes a fast test together with a setup and an executable which runs the test and displays the desired results. The test signal is provided as a linear coded wav file. This file can easily be coded into MP3 format using any commercially available or public domain wave editors or ripper programs. The test can also be executed by IEEE control and all results can be read out by IEEE commands.

The simple network management protocol (SNMP) can be used in a wide range of applications, as described in Rohde & Schwarz Application Note 7BM65 “The Simple Network Management Protocol: Remote Controlling for Monitoring Devices“. In particular, the option of centrally managing monitoring sensors – such as the R&S DVM for RF and baseband signals in digital broadcasting – shows the potential of this technology. However, the protocol alone is not enough to achieve this management functionality. Specialized management applications are needed that carry out the SNMP requests and display the results graphically. This application note and the associated SNMP example application will show how the R&S DVM family can be used for this type of application. Rohde & Schwarz customers can use the included source code (programming language: C#) to make the modifications needed for their own situations.
