Test drive a portable ScopeMeter
Fluke (UK) has introduced a test drive programme for the innovative 190 series high speed potable 'scope.
The prices remain unchanged.
The new Fluke 190B Series ScopeMeters, which replace the 190 Series, have a 20% larger screen, with a diagonal of 144cm.
The screen is also twice as bright as before and has improved contrast for easier interpretation of waveforms in all working conditions.

More ranges, features and resolution for DMMs
Fluke has introduced the Models 187 and 189 digital multimeters.
The 190B Series' 320 x 240-pixel screen resolution and 1200 samples per trace (up from 1000) further enhance on-screen detail and allow 12 horizontal (timescale) divisions.
All the new Fluke 190B Series ScopeMeters are two-channel oscilloscopes with separate high-speed digitisers per channel.
They are 1000V CAT II and 600V CAT III safety certified.
The top-of-the-range Fluke 199B model has a 200MHz bandwidth and 2.5Gsample/s real-time sampling rate per input.
The 196B has a 100MHz bandwidth (1Gsample/s sampling rate) while the 192B has a 60MHz bandwidth (500Msample/s sampling rate).
With a many times faster display update rate (similar to that of the 190C Series Colour ScopeMeters), signal changes are seen immediately, helping users to analyse complex, modulated or other fast-changing waveforms.
Faster display of dynamic signals is particularly useful when making fine adjustment of a system under test.
The 190B's ScopeRecord mode now also features a 'stop-on-trigger' function that allows the instrument to stop recording waveform data if the signal is interrupted or if a specific trigger signal is received.
This function is useful for recording and analysing power interruptions, machine failures and UPS takeover.
An automatic measurement function that allows users to measure the effective output voltage of variable speed motor drives and pulsewidth modulated power supplies is also built in.
Other features include a waveform-compare function allowing an acquired trace to be stored as a 'reference trace', which can be subsequently used to visually compare newly acquired waveforms.
The coverage of the TrendPlot function has been extended from 8 to 22 days.
The optional FlukeView PC software (V4.1) has been updated to handle reference templates, enter set-up descriptions and provide more download functions (a free update is available for V3.x users).
Despite the larger display and faster operation, battery life is unchanged.
The built-in NiMH battery pack still provides up to 4h operating time per recharge.
A battery charger (BC190), voltage probes, ground lead, 4mm probe tip, ground-lead-to-banana-plug cable and hard-point test leads (TL75) are all included.
