   INSTEK GPT-9903A   Description / Specification:    
INSTEK GPT-9903A 5KV AC, 6KV DC Withstanding Voltage / IR Tester

The GW Instek GPT- 9903A is capable of performing AC withstanding, DC withstanding and insulation resistance 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.

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.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot
Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
