The 9500B Oscilloscope Calibrator features

Automating oscilloscope calibration is possibly one of the biggest productivity enhancements that can be realized in many calibration labs. Performed manually, this work requires skilled operators to spend a substantial amount of time performing what are essentially repetitive tasks. Semi, or partial automation solutions apparently address this issue and free skilled technicians to perform more valuable tasks. However, in practice, these partial solutions present their own problems.

Over the last decade, the oscilloscope of choice has migrated from a two-channel instrument to a more complex four-channel device. When calibrating these instruments, it is necessary to move the calibrating signal from channel to channel as the procedure progresses. This can be achieved by physically moving cables, though this requires operator intervention. In high performance instruments, this may introduce additional measurement uncertainties as cables and connectors are handled. An alternative is to introduce a switching matrix to route signals, though this may result in problems with signal reflections, poor contacts and path differences that materially impact calibration uncertainties.

Active Heads and full automation

The Fluke Calibration 9500B addresses these issues, and provides true, full automation through the use of its unique Active Heads. With the 9500B, all the signals required to fully calibrate the oscilloscope are generated in detachable heads, remote from the calibrator mainframe. The heads are connected directly to the oscilloscope input without the need for additional cables. All control and switching of waveforms are performed under the control of the mainframe, yet within the head itself – typically only a matter of millimeters away from the oscilloscope input and amplifiers. With each 9500B mainframe able to control up to five heads, all the signals required to calibrate a 4-channel oscilloscope with an external trigger can be supplied, controlled and switched without operator intervention or the need for external switching.

MET/CAL® Plus Calibration Management Software

The final link in the chain of full automation is software. The 9500B Oscilloscope Calibrator can be used with Fluke Calibration’s powerful IEEE-488 (GPIB) based MET/CAL Plus automated calibration management software. While allowing you to automate the calibration process, MET/CAL also documents results, manages your calibration inventory, and allows you to develop new oscilloscope calibration procedures. Running under Microsoft Windows® and supporting multi-user networking, the software implements advanced features such as ISO 9000 compliant traceability, custom certificate and report generation, and high-level procedure programming. The result is higher workload throughput, better calibration consistency, minimization of human error, and less requirement for operator training – in short, higher quality calibration at lower cost.
