The Fluke PM 3370A is a 60 MHz, 2-channel hybrid oscilloscope combining digital storage and analog measurement modes in a single instrument. Designed for electronics troubleshooting, signal analysis, and laboratory testing, it delivers 8-bit vertical resolution with sampling rates up to 20 MS/s per channel (interleaved) or 10 MS/s simultaneous. The autoranging capability automatically optimizes vertical and horizontal scales for clear waveform display across diverse test scenarios.
