Audio Transcoder Key Generator Serial

The Avenue system includes modules for video up/down conversion, audio embedding, synchronization, conversion, routing, noise reduction, protection switches, test signal generators and more. Avenue signal processing modules are used worldwide in broadcast, mobile, satellite, cable, worship and post production facilities. Avenue is a tray-based signal integration system housed in a 1RU or 3RU frame. Any combination of 1.5 Gb/s HD, 3 Gb/s HD, SD, MPEG, analog video and audio processing modules can be used together in the same frame.

Audio Transcoder Key Generator Serial

Signal generators must be calibrated at regular intervals to maintain their rated accuracy for output level, carrier frequency, modulation depth, modulation frequency, and distortion. The FSMR provides the functions and precision required to perform signal generator and attenuator calibration without additional hardware or software. It combines a level calibrator, AM, FM, and PM modulation analyzers, an audio analyzer with THD and SINAD capability, RF power meter, and comprehensive spectrum analyzer functions in one instrument, and is available in frequency ranges from 20 Hz to 3.5 GHz, 26.5 GHz, and 50 GHz. Measurements include output level accuracy, carrier frequency accuracy, setting accuracy of modulation depth and deviation, weighted and unweighted spurious modulation, and modulation frequency response, distortion, and frequency. Key parameters are traceable to NIST and other national standards organizations.

The power meter integrated into the FSMR is compatible with both the Rohde & Schwarz NRP family of power sensors, and can control power meters from other manufacturers as well. The instrument as well as all sensors can be controlled via GPIB, Ethernet LAN, or from the front panel. Other features include an RF frequency counter with 0.01 Hz resolution, and an audio input for calibration of modulation generators.

For signals within the instrument's selectable measurement bandwidth, level measurements aren't affected by frequency drift, deviation, or residual FM. Over its selectable measurement bandwidth extending from 100-Hz to 10-MHz, the FSMR is insensitive to frequency offset or residual FM of the generator to be calibrated. Various audio filters, weighting filters, de-emphasis filters, and detectors are available for audio analysis, to speed residual FM measurements. 350c69d7ab
