The 3789B is a more powerful test set than the 3789A offering outstanding monitoring and troublehooting capabilities. A built-in demultiplexer allows it to perform measurements on both DS1 and DS3 signals from a DS3 access point. It provides all the basic pattern generation and error measurement capability required for the installation, commissioning and maintenance of DS3 digital transmission equipemnt including cable, digital radio, satellite and lightwave systems.

FEATURES:

• Binary bit-by-bit error detection
• Parity frame and BPV error measurements
• Single-key measurement setup using preset memory
• Built-in DS3 to DS1 demultiplexer
• Error & jitter tests at DS1 and DS3
• M13 & C-Bit parity generation and measurement
• DS3 idle signal generation and detection
   
• OPTION 003: 2nd measurement capability (including C-bit parity generation.measurement and jitter measurements at both DS1 and DS3
• OPTION 010: 24-column built-in printer
