Description

Tau-Tron S5104 DS1/DS1C/DS2 Digital Transmission Test Set Option 03 GPIB

Benchtop test instrument for DS1, DS1C, and DS2 digital transmission line testing. Measures bit error rate, bipolar violations, jitter, and frame alignment on telecom circuits.

Specifications & What's Included

  • Supports DS1/DS1C/DS2 signal standards with NRZ interface
  • Transmitter outputs: DS1 Bipolar, NRZ Data, NRZ Clock
  • Receiver inputs: DS1/DS1C/DS2, NRZ Data, NRZ Clock
  • Error injection: Frequency, BIT, ERR Free, BPV, AMPL, INT, EXT
  • Measurements: BIT, BPV, Jitter, Frame, Status
  • Remote control via GPIB (IEEE-488) and RS-232
  • Front-panel LED numeric displays and status indicators
  • Connectors: BNC, DB-25 (RS-232), GPIB

Applications

Used in telecommunications and data transmission environments for characterizing DS1 and DS2 circuit performance. Tests transmission lines, identifies signal impairments, and validates equipment compliance with telecom standards. Commonly deployed in carrier network operations centers and equipment labs during the 1980s–2000s for line conditioning and troubleshooting.

Condition: Used
This Tau-Tron S5104 DS1/DS1C/DS2 Digital Transmission Test Set has been inspected and is in good cosmetic condition. The unit powers on — both the Transmitter and Receiver LED displays light up and are active — but has not been tested further beyond power-on. The chassis shows normal wear consistent with prior lab or field use; the front panel lettering and controls are clean and legible. The rear panel BNC connectors, GPIB interface, and RS-232 DB-25 port all appear intact. This unit was manufactured in Chelmsford, MA and carries Option 03 (serial number 8409230). Please view our photo set and contact us if you have any questions.
