DataSYS 7200 Applications

Tremendous flexibility is the hallmark of the unique DataSYS 7200. Here are just a few examples:

• Recording waveform detail over a period of hours while the unit under test is being monitored over varying temperatures; the waveform detail can be measured and graphed during replay to show variation in performance such as risetime, pulse width or input and output power.
• Automatically acquiring waveforms for a defined time at preset intervals. This allows detailed waveform performance to be captured at preset periods during a long term test.
• Acquiring waveforms during an engine start period and saving for subsequent analysis.
• Slow recording using high speed glitch capture to find random spurious events over long time intervals. Using the Replay function, accurate timing will give time of occurrence.

The display above shows waveforms in Replay with softkey controls for forward and reverse. A Move control is operated by the cursor control with a display of screens and elapsed time.

• While in Replay, traces can be zoomed to show fine detail.
• During Replay, measurements can be made on the trace or the output recorded on paper.
• Graphing and histogramming analysis can also be performed during Replay.

Measuring power of a complex waveform.

With modern switching techniques being extensively used throughout industry, it is important to measure the performance of switch mode supplies.

The DataSYS 7200 waveforms shown above are acquired voltage and current with the calculated power waveform supplying a laser. The current is pulsed, producing a large number of harmonics. Custom Measurements are set up to measure live - over a precise number of cycles - the rms voltage, rms current, VA, real power and power factor. The measurements are performed to ensure standards are met for power loading.
