Fluke PM 3380A Autoranging CombiScope, 100 MHz, 2-Channel

The Fluke PM3380A Autoranging CombiScope is a dual-channel, 100 MHz oscilloscope that switches between digital storage and real-time analog modes. This hybrid architecture delivers both the waveform capture capabilities of a DSO and the signal-following responsiveness of analog operation, making it ideal for complex signal characterization across engineering and laboratory environments.

Technical Specifications

• Bandwidth: 100 MHz


• Channels: 2 analog channels


• Sampling Rate: 200 MS/s repetitive signals; 100 MS/s single shot


• Input Impedance: 1 MΩ


• Timebase: Main timebase 0.5 s/div to 50 ns/div (1-2-5 sequence); Delayed timebase 0.5 ms/div to 50 ns/div; fastest sweep 5 ns/div at 10× magnification


• Vertical Deflection: Continuously variable with autoranging optimization


• Record Length: 8K samples standard; expandable to 32K for single trace or 200 traces at 512 samples each


• Sampling Technique: Digital oversampling peak-detect mode captures transients as narrow as 5 ns at correct amplitude

Key Features

• Full trigger capability: Auto, Single, Edge, and TV modes (NTSC/PAL/SECAM/HDTV)


• Pre- and post-trigger acquisition with external trigger support


• Autoset function configures channel, timebase, and trigger parameters automatically


• Touch-Hold-and-Measure™ function displays VDC, VRMS, Vpk-pk, and frequency measurements


• Cursor-based measurements with autoranging horizontal and vertical control


• Graphical display for intuitive waveform visualization

Typical Applications Complex waveform capture, transient analysis, signal characterization, and detailed measurement tasks requiring both digital precision and analog responsiveness.
