Description

Tau-Tron STX-1101 Bit Error Rate Transmitter GPIB RS-232 120VA 47-440Hz BERT

Benchtop bit error rate transmitter used for testing and measuring digital transmission quality in telecom and data communications systems. Generates test patterns and injects errors for BERT analysis on serial data links.

Specifications & What's Included

  • Model: STX-1101 | Manufacturer: Tau-Tron (General Signal)
  • Power: 120 VA / 75 W max, 47–440 Hz AC; accepts 90–132 VAC or 180–264 VAC
  • Interfaces: GPIB and RS-232 with local/remote/return-to-local control modes
  • Data patterns: 2^6-1, 2^9-1, 11110000 (selectable)
  • Error injection: Internal and external with selectable rates and single-error mode
  • Outputs: Pattern, Clock (TTL), and Data (50 Ohm) with adjustable amplitude and baseline offset
  • Additional features: Clock loss indicator, data inhibit (TTL), sync outputs terminated at 50 Ohm
  • Unit only; no accessories included

Applications

BERT instruments like this were used in telecommunications labs and manufacturing test environments to validate modem performance, verify data link integrity, and characterize error rates on serial communications lines. Commonly connected to legacy telecom test systems, data transmission equipment, and serial interface testing setups from the 1980s through early 2000s.

Condition: Used
This Tau-Tron STX-1101 Bit Error Rate Transmitter has been inspected and appears to be in good used condition. It was pulled from a working environment where it was in use and functional. The blue benchtop enclosure shows typical handling wear consistent with lab use. The front panel controls, indicator LEDs, and BNC connectors appear intact. The rear RS-232 and GPIB connectors are present. The line voltage selector is visible on the rear panel. Please view our photo set and contact us if you have any questions.
