Fluke (UK) has introduced a test drive programme for the innovative 190 series high speed potable 'scope.
The colour display on the new Fluke 190C Series of ScopeMeters makes identification of individual waveforms easier on the screen, particularly when displayed with large amplitudes.
It also makes it possible to visually distinguish individual traces if waveforms are displayed on top of, or very close to, each other.
Colour is used for warnings and other on-screen labels, making it easier to distinguish them and to link information to specific waveforms.

Fluke sweetens ScopeMeter package
Fluke UK is offering a free accessory kit worth over £280 for all customers trading in an oscilloscope when purchasing a new Fluke ScopeMeter 190 Series.
The brighter, high contrast display allows for clear reading under varying light conditions.
Thanks to a newly designed digital signal processing core, a digital persistence mode gives the instrument an analogue oscilloscope like waveform decay, especially useful when working with complex or modulated, dynamic signals.
Whereas an oscilloscope's display normally represents the amplitude of a signal as a function of time, the digital persistence mode shows the amplitude distribution over time using multiple intensity levels and a user selectable decay time.
With the many times faster display update rate, signal changes are seen immediately, giving an actual representation of the dynamic behaviour of the signal.
A faster display of signal changes is also particularly useful when making fine adjustments of a system under test.
The higher screen resolution (now 320 x 240pixel), the 20% larger screen and a deeper memory (1200 instead of 1000 samples in scope mode, or 27,500 samples in ScopeRecord mode) enhance the waveform detail to be displayed for a longer period of time.
Other new features include a 'stop on trigger' to store pretrigger waveform data in the scope record mode and a 'waveform reference' feature allowing an acquired trace to be stored as 'reference' to visually compare new waveforms against.
To allow users to measure the effective output voltage of variable speed motor drives and frequency inverters, a Vpwm measurement is also built in.
The latest FlukeView software release supports the use of colour for waveforms in documentation.
The 199C, with 200MHz bandwidth and 2.5Gsample/s real time sampling, and 196C (100MHz, 1Gsample/s), are two-channel oscilloscopes with independently floating isolated inputs up to 1000V.
With the speed, performance and analysis power usually found only on high-end bench oscilloscopes, they help users to solve virtually all electronics measurement problems encountered in the field.
The complete ScopeMeter 190 Series provides unique features like connect-and-view trigging and automatic capture and replay of the last 100 screens.
All Fluke 190 Series ScopeMeters are 1000V CAT II and 600V CAT III safety certified (EN-61010-1).
As hand-held instruments, long battery life is essential and the new 190C Series provides the same four hours operating time per recharge of the NiMH battery packs.
The Fluke 199C and 196C are now available from Fluke distributors and representatives worldwide.
Prices in the UK are GBP 2352 for the 199C and GBP 2659 for the 199C/S (with hard case, optically isolated RS-232 interface cable and FlukeView software) and GBP 2039 for the 196C and GBP 2346 for the 196C/S (with hard case, cable and FlukeView software). Request a free brochure from Fluke (UK) ...
