AEROFLEX-IFR 2843 Digital Communications Analyzer

The Aeroflex IFR 2843 Digital Communications Analyzer is a hand-held analyzer for installation and maintenance measurements on digital 2 Mbit/s lines and equipment with data interface testing ability. 2 Mbit/s framing systems with 30 and 31 channels, with and without CRC4, are generated and received to enable a range of tests on framing, alarms and signalling. Individual channels can be tested at 64 kbit/s, assisting in testing and fault location within digital data networks and cross connect switches. n x 64 kbit/s channels can be tested where they are carried within 2 Mbit/s digital signals. 2 Mbit/s and data circuits and equipment can be tested in a fully integrated test instrument, with mixed mode data and 2 Mbit/s testing possible for maximum flexibility. Data test interfaces provided are RS-232, X.21, V.35, RS-449 (V.36), codirectional and contradirectional. Both synchronous and asynchronous modes are possible with a wide range of standard and user programmable data rates. Independent transmitter and receiver enable connection to data and 2 Mbit/s interfaces simultaneously. Dual receiver inputs enable connection of two 2 Mbit/s HDB3 signals for measurement of clock slips. Voice channels within a 2048 kbit/s signal on either receiver can be monitored in-service (A/B Audio) and routed to an internal loudspeaker or a headphone socket for a first level check of analog level and quality. 64 kbit/s data channels can be routed to a V.11 interface for external measurement, for example connection of common channel signalling to a protocol analyzer.

*This is a Web introductory price for one calibration of the AEROFLEX-IFR 2843. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Decibel (dB)
A unit of measurement of optical power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Plesiochronous Digital Hierarchy (PDH) is a transmission system for voice communication using plesiochronous synchronisation. The transmitter adds dummy information bits to allow multiple channels to be bit interleaved. The receiver discards these bits once the signals have been demultiplexed. PDH combines multiple 2 Mb/s (E1) channels in Europe and 1.544 Mb/s (DS1) channels in the US and Japan.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).
