MAIN FEATURES

There are five models in this family of FLUKE oscilloscopes. Each of these models is a combination of an analog real-time oscilloscope and a fully featured digital storage oscilloscope. By pressing a single key, you can switch the instrument from the analog mode to the digital mode and back. This allows each of the units to be used in an optimum operating mode for all kinds of signal conditions. Complex data streams, modulated waveforms, and video signals can often best be seen in the analog mode of operation. The digital mode of operation is more suited for single events, signals with low repetition frequencies, and when automatic measurements need to be performed.

In this family there is a choice of five models. Two models have a bandwidth of

200MHz, two have a bandwidth of 100 MHz and one has a bandwidth of 60 MHz. Beside the 2 channel models with EXT TRIG input, there is a choice of two models with four fully featured channels, all shown in the following table:

Type Number	Bandwidth	Sample rate	Number of	Input
			Channels	Impedance
PM3370B	60 MHz	200 MS/s	2	1 MΩ
PM3380B	100 MHz	200 MS/s	2	1 MΩ
PM3384B	100 MHz	200 MS/s	4	1 MΩ
PM3390B	200 MHz	200 MS/s	2	1 MΩ/50Ω
PM3394B	200 MHz	200 MS/s	4	1 MΩ/50Ω

In the same instrument family, there are two 200-MHz and two 100-MHz analog oscilloscopes that have specifications similar to the above-mentioned analog/ digital combination oscilloscopes operating in analog mode.

All analog/digital combination oscilloscopes listed above have the following features:

-Autoranging attenuators.

-Realtime clock.

-32K sample acquisition memory in 4 channel versions.

-8K sample acquisition memory, expandable to 32K in 2 channel versions.

-Up to 40 waveforms stored in memory or 204 waveforms with optional memory extension.

-Autoset function for an instant optimized signal display at the touch of a button.

-Autoranging timebase.

-Cursor measurements with 1% accuracies.

-Extensive set of fully automated voltmeter and time measurement functions.

-Probe operated ’Touch Hold and Measure’ function freezes the display and instantly displays the signal frequency, amplitude and dc voltage level.
