Waveform Recorder, Computerized

Transient waveform recording forms an important part in behavioural testing of many products and systems in dynamic conditions. AG Measurematics, a company specializing in measurement and control instrumentation, offers a computerized waveform recorder, ADSOF 4. This is a state-of-the-art application software compatible with Windows 95 and 98. Application includes study of power line transients, short circuit testing of generators, aircraft engine testing, operation and release characteristics of solenoid valves, contractors and relays, study of force transients created due to impact (TUP hammer), and high frequency and turbulence effect on structural components under two-phase hydraulic flow conditions. When the system is used with high speed 16-channel A-D PC add-on card, the computer gets transformed into a transient recording system which replaces UV oscillographic recorders. It can acquire high speed transients, display them as curves on colour monitor, determine time between two cursors, calculate slope of any portion of displayed transient waveform and print the results in form of a test report through an inkjet, laser or dot matrix printer. Up to 16 waveforms can be viewed on the same screen in different columns. Other facilities include zooming of any programmable pre-trigger interval and record duration, display of X and Y coordinates of cursor position (for measurement of the curve), data conversion and storage to files in ASCII (text) format for transferring into other programmes such as Excel, Lotus 123, Grapher, etc. Operator entry screen allows operator to enter test number, part number, type of test, test header, etc, for printout on test report.
