Fluke PM3084 Analog Oscilloscope, 100 MHz, 4-Channel

The Fluke PM3084 is a 100 MHz, 4-channel analog oscilloscope engineered for signal analysis, waveform visualization, and electronics troubleshooting. It delivers 1% deflection factor accuracy across vertical and timebase measurements, supported by edge and TV triggering modes, delayed timebase, and AUTOSET/AUTOCAL functionality for rapid setup and performance optimization under variable environmental conditions.
