In the manufacture, distribution and service of the electronic test tools, biomedical equipment and networking solutions, the Fluke Corporation is the leading group all over the world. In order to analyze the signals better, Fluke has released the dual-input ScopeMeter 190 series of handheld oscilloscope. Waveform resolution is provided by all the color and monochrome models, therefore, the users are able to gain the more detail information about the signals.

The frequency spectrum analysis which uses the Fast Fourier Transformation analysis as a stand is also contained in the color models, as well as two new triggering modes and ’cursor-limited’ automatic measurements. With safety certification to 1,000 V CAT II and 600 V CAT III, Fluke ScopeMeters help users to safely solve virtually all electronics measurement problems encountered out in the field. The battery-powered Fluke ScopeMeter 190 Series offer up to 200MHz bandwidth and 2.5 GS/s real time sampling rates, the speed, performance and analysis power usually found only on high-end bench oscilloscopes. Bandwidths start at 60 MHz for the entry level 192B. The waveform memories on all models have been increased by 150%, allowing as many as 3000 samples per channel to be acquired. This greatly increased waveform resolution can be used with the new 16x Zoom function to find tiny details in a long waveform, for example the color burst in a video signal or a single pulse in a complex data-stream. The high-resolution waveforms can be transferred to a PC running optional FlukeView ScopeMeter software for documenting, archiving and analysis.


The Frequency Spectrum Analysis using FFT is included in all 90C Color Scopemeters. This makes if possible to identify individual frequency components in a signal, and to discover the effects of vibration, signal interference or crosstalk. The standard ’Connect-and-View™’ automatic triggering function greatly simplifies triggering, but since manual triggering is sometimes required, two new modes have been added to the 190C color series. N-cycle triggering ensures stable ’live’ images of a signal, for instance, in frequency dividers and clocked digital systems. Dual-slope triggering enables triggering on both rising and falling edges, so that any edge will act as a triggering event - especially useful, for example, when making eye-patterns from digital streams. The 1 90C models now also feature automatic power and Vrms measurements. These can be performed on a specific, user identified portion of a waveform, with the cursors used to define the lime-window of interest. This is ideal for measuring power during the first mains cycle after closing the mains switch.

All ScopeMeter models feature a large 320 x 240 pixel display, a fast display update rate, up to 1 000 V independently floating isolated inputs, a focility for measurement of effective output voltages of variable speed motor drives and frequency inverters and a 5000 counts true-rms multimeter function. self-paced oscilloscope Training Modules, one set based on general Oscilloscope Theory, the second set explaining best-practice in the use of Fluke ScopeMeters are also included in the free fluke ScopeTraining.
