   INSTEK GPT-9901A   Description / Specification:    
INSTEK GPT-9901A 5KV AC Withstanding Voltage Tester

The GW Instek GPT- 9901A is capable of performing AC withstanding tests needed for the compliance of the safety standards such as IEC, EN, UL, CSA, GB, JIS and other safety regulations. The output voltage is automatically cut off (within 150µs) upon the detection of an abnormal output voltage or a trip of current limits during test to protect the operator from hazardous injury. It automatically discharges the DUT after each test to eliminate excessive voltage that remains on the DUT.

*This is a Web introductory price for one calibration of the INSTEK GPT-9901A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS or root mean square is a statistical measure of the magnitude of a varying quantity
