HP J2527A Transmission Impairment Measurement Set

The HP J2527A TIMS interface for the HP Internet Advisor provides basic analog tests to qualify circuits for voice, data, broadcasts and ISDN. Operation of the HP J2527A is based on the industry standard family of HP TIMS products: HP 4934A, HP 4935A and HP 4936A. When the HP J2527A TIMS interface is attached to the Internet Advisor using an undercradle, the datacom specialist has full decoding of LAN and WAN protocols, bit error rate measurements and transmission impairment measurements -- all under one handle.

[ Features ]
The HP J2527A TIMS interface includes the following features:

50 Hz to 200 kHz operation
Level/frequency, noise and noise-to-ground, noise-with-tone and signal-to-noise, 3-level impulse noise, and P/AR
IEEE 743-1984 and CCITT compliance
Microsoft Windows^® user interface based upon operation of the HP 4934A, HP 4935A and HP 4936A
Easy to use interface.
