The ScopeMeter 190 Series has been expanded to include the 196C and 199C. The newer Fluke ScopeMeter 190C series, available from Spescom MeasureGraph, features a large, high-resolution colour screen – and extended functionality including Digital Persistence and a much faster display update rate. These high-performance handheld oscilloscopes help users to solve virtually all electronics measurement problems encountered in the field.
The benefits of colour
A colour display makes identification of individual waveforms easier, particularly when displayed with large amplitude on screen. It also makes it possible to visually distinguish individual traces if waveforms are displayed on top of, or very close to, each other. Larger waveforms can be displayed without confusion between individual traces. Colour is also used for warnings and other on-screen labels, making it easier to distinguish them and to link information to specific waveforms. The brighter, high contrast display allows for clear reading under varying light conditions. And still the four hours battery operating time is assured!
See waveforms as per analog scope
Thanks to a newly designed digital signal processing core, a digital persistence mode gives the instrument an analog oscilloscope like waveform decay, especially useful when working with complex or modulated, dynamic signals. Where 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, resulting in a waveforms display similar to that of an analog oscilloscope. 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.
See more signal detail
The higher screen resolution (now 320 x 240 pixels), 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.
Many more new functions
Other new features include a 'Stop on trigger' to store pre-triggered waveform data in the Scope Record mode and a 'Waveform Reference' 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.
When the original ScopeMeter 190 Series was launched two and a half years ago, it introduced field engineers to handheld instruments with the speed, performance and analysis power usually found only on high-end bench oscilloscopes. The top-of-the-range Fluke 199 model has a 200 MHz bandwidth and 2,5 Gsa/s realtime sampling rate per input, there are also 100 MHz and 60 MHz models. They all are two-channel oscilloscopes with independently floating isolated inputs up to 1000 V. The ScopeMeter 190 series provide unique features like Connect-and-View trigging and automatic capture and replay of the last 100 screens. The latest additions, the 199C (200 MHz bandwidth and 2,5 Gsa/s realtime sampling) and 196C (100 MHz/1 Gsa/s) bring the benefits of a full-colour display to handheld scopes.
All Fluke 190 Series ScopeMeters are 1000 V CAT II and 600 V CAT III safety certified (EN-61010-1). As handheld instruments, long battery life is essential. Therefore, the new 190C Series provide the same four hours operating time per recharge of the NiMH battery packs. Extensive user documentation is supplied on CD-ROM (in PDF-file format) in nine languages.
