Keysight (Agilent) 37724A SDH/PDH Test Set

The HP 37724A is a comprehensive, field-portable SDH/PDH test set for applications up to 622 Mb/s (STM-4). It provides generation and analysis of TU-12 (2 Mb/s) and 140-Mb/s mapped SDH signals, with full control of regenerator section, multiplexer section, and path overhead bytes. Plug-in modules provide connection to a range of optical interfaces. Errors, alarms, and G.783 pointer movement sequences are generated to stress equipment up to and beyond CCITT standards. Frame Formats: STM-l and STM-4. Mappings: 2 Mb/s (all TU-12 modes) and 140 Mb/s to CCITT G.709. Test Interfaces; Optical: 155.52 and 622.08 Mb/s (1310 nm). Coded electrical: 2.048 (HDB3), 139.264 (CMI), and 155.52 (CMI) Mb/s. Add/drop: 2 Mb/s, 140 Mb/s, STM-l, and overhead DCC channels. Overhead: Standard and user-programmable section, line, and path overhead bytes

*This is a Web introductory price for one calibration of the Keysight (Agilent) 37724A. 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.


Related Communication Terms and Definitions. For a complete list go to our  Terms and Definitions Page.

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.

PDH
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).
