1MA83 GDE (= Generic Demonstration Engine) is a easy-to-use, free-of-charge remote control command sequencer tool. The big advantage is that the test description is stored in a simple, easy-to-read text file, and loaded in GDE at runtime. This makes it very easy to modify tests by the user or add additional tests to already existing test solutions without redistributing big setup files. Remote Control
RAC-0502-0012 This Application Note presents a program which combines FM tuner measurements to form automatically running sequences in line with DIN EN60315-4. It is an extension of Application Note 1GA43 and can be used with the Generator R&S SML and the Audio Analyzer R&S UPV or UPL.

1GA43 A great number of measurements have to be performed to determine the quality of FM tuners. This Application Note presents a program that permits these measurements to be carried out in line with DIN EN60315-4.

7BM44 A lack of lip synchronicity is an effect that can severely impair the quality of TV reception. With modern digital signal processing, this audio-to-video delay occurs much more often than in earlier times when analog signal generation was used. The total delay can reach several hundred milliseconds, which is immediately noticeable on a TV home receiver. To prevent such impair-ments, the audio-to-video
1GA42 The UPL Audio Analyzer can be remote-controlled via the IEEE bus or the RS-232-C interface. Test results are output either individually or in blocks. ASCII or binary files such as setup files can be transferred to the audio analyzer from an external controller. This Application transfers files from the audio analyzer to an external controller via the serial interface. Utility programs for the
1GA30 Present-day sound studios are hardly conceivable without A/D converters. A/D converters are essential components when music is recorded and they directly influence the recording quality. The current Application Note describes a test program permitting automatic measurements of all parameters of sound studio equipment with the aid of Audio Analyzers UPD or UPL. Measuring converter chips with mostly
1GA32 In many applications, circuitries with automatic gain control are used, for example in the fields of tape recording or hearing aids. This application note describes the typical characteristic of these control circuitries and the difficulties in measurements using oscilloscops. With the audio analyzers UPL and UPD these measurements can be done much easier, the analysis can be done manually or
1GA33 Many measurements in audio applications have to be monitored for compliance with specified limit values. Therefore, sometimes a whole series of measurements have to be compared with a fixed limit value, in other case it might be necessary to define different tolerances for example for different frequency ranges. Both can be done using Audio Analyzer UPD or UPL. This application note covers the
1GA23 In modern telephoning, dual-tone dialling is used more and more often. Every symbol to be transmitted is coded by two frequencies which are sent at the same time. To ensure a trouble-free call setup, transmission has to be done within defined tolerances. For measuring these kind of dialling signals, the measurement equipment has to fulfill high requirements. This application note describes how
1GA31 Interferences on audio transmissions, which happens only from time to time, are very difficult to be measured. This application note describes a method, used by the audio analyzers UPL and UPD, to monitor test tones without any interruption and detecting even the shortest clicks.

1GA15 For the transmission of digial audio data, different data formats are in use. The AES/EBU format, which is used in professional applications, as well as the S/P DIF format used in consumer electronics, transmit the audio data in time multplex for both channels. Additonal bits in the data stream cover complementary information, respectively are used for error detection.The generation and the analysis
1GA36 Being faced with a wide variety of standards and manufacturer’s specifications, test engineers may often find it difficult to keep track of necessary audio measurements. This is aggravated by the fact that modern audio analyzers offer a multitude of settings. This application note serves as an aid offering a collection of typical setups that make it possible to get started with measurements immediately
1GA34 There are proposals for broadband measurements on hearing aids, for example the proposed standard ANSI S3.42. Such measurements are intended to simulate more accurately the behaviour of hearing aids under normal hearing conditions also in the presence of ambient noise. Audio Analyzer UPD fitted with High-Speed Option UPD-B3 makes it possible already now to generate the proposed test signal and
1GA12 When measuring audio components with unknown transients, the experienced engineer watches the settling of the DUT before accepting a measured result to be valid. The settling function in the UPL/UPD simulates this process and automates it by continuously comparing the measured value with a number of measured values stored before. A measured value is only accepted as being valid if it is within
