Used Bradley Electronics Type 192 Oscilloscope Calibrator — USED / TESTED

Bradley Electronics (Datrend) · Portable Calibrator · Signal-Level Standard

The Bradley Electronics Type 192 is a portable oscilloscope calibrator, time-mark generator, and precision signal-level standard originally built by Bradley Electronics (legacy US) and now supported within the Datrend Systems test & measurement (T&M) portfolio. This unit is sold USED / TESTED — bench-verified against a working reference, cleaned, and shipped with a 30-day functional warranty. It generates calibrated square, pulse, sine, and triangle waveforms for verifying the amplitude accuracy, frequency response, bandwidth, and rise-time performance of analog and digital storage oscilloscopes.

KOEED normally focuses on PLC, HMI, servo, and CNC spare parts across Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic, and KEYENCE. We extend the same multi-brand sourcing capability into adjacent legacy T&M and MRO consumables for calibration labs that keep those nine automation platforms running.

Key Technical Specifications & Overview

Application Scenarios — Where It Fits

The Type 192 is a long-standing reference generator in metrology and instrument-repair environments. Typical deployment sites include:

• ISO/IEC 17025 calibration laboratories verifying the DC voltage, time-base, and bandwidth accuracy of analog and digital storage oscilloscopes.
• Industrial metrology rooms inside plants running Allen-Bradley, Siemens, and Mitsubishi automation lines — where oscilloscope trace accuracy is part of the documented test plan.
• ATE and electronics-manufacturing QA stations that need a stable amplitude / time reference before product release.
• Field-service and instrument-repair shops supporting Fanuc CNC and Yaskawa servo cabinets that still rely on analog scope front-ends.
• Vocational training labs and university electronics programs that need an affordable, lab-grade calibration source.

Integration & Wiring Notes

The Type 192 is a stand-alone signal source — it does not connect to a PLC or a fieldbus. It is the reference instrument sitting on the bench next to the device under test. Two output paths matter in practice:

The Type 192 is the “golden source” — it is not wired into Omron SYSMAC, Schneider Modicon, or Panasonic FP backplanes. Treat the cables like precision probe leads: keep them short, do not bundle with power wiring, and replace any coax with intermittent shielding. For routine bench math, the KOEED PLC Analog Calculator and PLC Hex to Float Converter help convert scope-trace readings back to engineering units.

Installation & Commissioning Tips

1. Inspect the transit case on arrival. Used T&M instruments spend years on service-truck shelves; verify that the inner foam has not collapsed and the BNC connectors have not been knocked out of alignment.
2. Warm up for at least 30 minutes before any trace-accuracy check. The reference resistors and ovened zeners inside the Type 192 need thermal equilibrium to stay within spec.
3. Confirm line-voltage switch on the rear panel (115 V vs 230 V) before first power-up — a used unit imported from North America will still be set to 115 V by default.
4. Run the built-in self-check (most Bradley calibrators expose a front-panel “CAL” or “TEST” position). Record the reading on the data plate for the maintenance log.
5. Verify the 1 kHz / 1 V reference against a known 6½-digit DMM; the deviation should be inside the unit’s published amplitude spec.
6. Log into your asset register with a calibration due-date that matches your lab’s ISO 17025 cycle. The KOEED PLC Error Code Database and AI Diagnostic Tool are good companions when you trace a suspicious scope reading back to a faulty module in an KEYENCE vision system or a Fanuc servo loop.
