There are four 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 push button, 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 four models. Two models have a bandwidth of 200 MHz; the two others have a bandwidth of 100 MHz. There is a choice of two models with four fully featured channels or four channels in a ’2+2’ configuration In the same instrument family, there are two 200-MHz analog oscilloscopes that have specifications similar to the above-mentioned anaiog/digital combination oscilloscopes operating in analog mode. All analog/digital combination oscilloscopes listed above have the following features: - 8K sample acquisition memory, expandable to 32K. - 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. - Auto-ranging attenuators. - Auto-ranging timebase. - Real time clock. - 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. Peak detection for the capture of glitches as narrow as 5 ns. - Pattern, State and Glitch triggering (2 ns) - Event delay and pretriggering and posttiiggering. - TV triggering including HDTV and TV line selection. - Serial interface for printing and plotting. - Averaging to reduce signai noise and to increase the vertical resolution from 8 to 16 bits. - Advanced mathematics, including digital Sow-pass filtering. A Math+ option adds integration, differentiation, histogramming, and (as part of a option) FFT. - Sine interpolation and magnification which enables true to life four channel single shot acquisitions with a timebase up to 625 ns/div (32x magnified) - A delayed timebase with full trigger features. - An EIA-232-D interface (standard) and an GPiB/IEEE-488 interface (optional). - Autocal for automatic fine tuning of all circuitry to achieve maximum accuracy under all user conditions. - Closed case calibration for efficient maintenance of traceable calibration at minimum cost. The following options are available: - A MATH+ option with more automated measurement functions including envelope and measurement pass/fai! testing. Aiso included in this option are Integration, Differentiation, Histogramming, and FFT, - Memory extension offering 32K acquisition length and the ability to store 204 traces (of 512 samples each) in memory. IEEE-488.2 interface using the new SCPI (Standard Commands for Programmable Instruments) industry standard for remote control of test and measurement equipment.
