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
200 MHz, 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:
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.
