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
