FLUKE 1507 Insulation Resistance Tester

The Fluke 1507 insulation resistance tester features an insulation test range from 0.01 MΩ to 10 GΩ and insulation test voltages of 50 V, 100 V, 250 V, 500 V, 1000 V. It has live circuit detection that prevents insulation test if voltage > 30 V is detected for added user protection.

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
