Fluke PM 3370B Autoranging CombiScope, 60 MHz, 2-Channel

The Fluke PM 3370B is a 60 MHz, 2-channel benchtop oscilloscope combining analog real-time and digital storage acquisition modes. This dual-mode architecture enables operators to select between analog display for complex or modulated signals and digital storage for single events, low-frequency analysis, and automated measurements. The instrument delivers up to 200 MS/s single-shot sampling with 10 GS/s equivalent sampling on repetitive signals, paired with user-partitioned acquisition memory supporting up to 32K long records or over 200 traces of 512 points each.
