HP 37722A telecom analyzer HP 37732A telecom/datacom analyzer T echnical specifications.
2 Introduction The HP 37722A telecom analyzer is an easy-to-use, lightweight field- portable test set for in-service and out-of-service bit error and signal measurement on CEPT digital circuits and services. The HP 37722A analyzer provides framed/unframed pattern generation and measurements at and 2 Mb/s.
3 Telecom specifications Bit rates: 2.048 Mb/s, 64 kb/s; optional 8.448 Mb/s, 704 kb/s, sub- 64 kb/s. Frame structure: 2 Mb/s unframed, to ITU-T G.704, G.706, G.732, G.704: with no multiframe; with CAS multi-frame with/ without CRC4 multiframe; 64 kb/s codirectional; independent setting for transmitter and receiver.
4 Datacom specifications Datacom interfaces: V.24, V.11/X.21-leased, V.35. Terminal emulation: DTE, DCE. Timing modes: Synchronous from 50 b/s to 2.048 Mb/s; asynchronous from 50 b/s to 19.
5 Graphics and printing Graphic display and printout Barchart (results v 1920 time periods) for current or stored measurement period. Showing, for telecom: bit error count, code error count, frame err.
6 8 Mb/s measurements (Option 002) Adds framed and unframed pattern generation and measurements at 8 Mb/s. All specifications same as 2 Mb/s except: Clock: 8.448 Mb/s (internal), 500 kHz to 9 MHz (external). Line code: HDB3. Ternary data input: 8.448 Mb/s ± 100 ppm.
7 Relative frequency and bit slips (Option 010) 2.048 Mb/s only Measures relative frequency of, and bit slips between, two ITU-T G.703 2 Mb/s signals. Results displayed as + ve and − ve peak wander (UI), cumulative bit slips, frequency offset (ppm) and graph of bit slips (256, 16 UI).
