The Fluke PM 3380B ...94B series are the world's first AutoRanging Digital Storage Oscilloscopes with a complete Analog Oscilloscope built in.

Fluke CombiScopes® are a powerful combination of a genuine analog oscilloscope and a powerful digital oscilloscope in one instrument. Designed to fit any budget, there are 5 models in the CombiScope B series: three 2 channel models with bandwidths of 60, 100 or 200 MHz and two 4 channel models with 100 or 200 MHz bandwidth.

Fluke CombiScopes offer the best of both worlds:
