Handheld scopes enhanced for video imaging

The new upgraded Fluke ScopeMeter handheld oscilloscopes have enhanced sensitivity and a new troubleshooting feature.

The new upgraded Fluke ScopeMeter handheld oscilloscopes, with enhanced sensitivity and a new troubleshooting feature, are now available from TTi (Thurlby Thandar Instruments).

The new range includes four-colour and monochrome models for engineers servicing medical imaging and high-resolution video equipment.

With the speed, performance and analysis power usually found only on high-end bench oscilloscopes, and with safety certification to 1000V Category II and 600V Category III, the new instruments will help users to solve virtually all electronics measurement problems encountered in the field.

The new Models 196/C and 199/C offer double the maximum sensitivity on the y-axis, giving 2mV per division for greater measurement accuracy.

A new troubleshooting feature offers automatic waveform comparisons, against a reference trace, for "pass/fail" testing.

In this mode, the oscilloscope automatically stores the most recent 100 pass and 100 fail traces in memory, which can then be scrolled or rerun at the touch of a button.

The range also includes four new medical ScopeMeters: the monochrome 196BM and 199BM, and the colour 196CM and 199CM.

These offer all the standard functionality of the 196 and 199 instruments, plus measurement capabilities optimised for servicing medical imaging equipment and video systems, including X-ray, MRI, nuclear medicine and ultrasound machines.

These features include current-over-time measurement (in milliamperes), triggering on high-resolution noninterlaced video signals, smart averaging and extended offset.

All 199 models offer 200MHz bandwidth and 2.5Gsample/s real-time sampling, whereas the 196 models have 100MHz bandwidth and 1Gsample/s sampling.

The colour display on the 199 versions makes identification of individual waveforms easier on the screen, making it possible to visually distinguish individual traces if waveforms are displayed on top of, or very close to, one another.

A digital persistence mode gives the instrument an analogue oscilloscope-like waveform decay, a feature that is especially useful when working with complex or modulated, dynamic signals.

All ScopeMeter models now have a large 320 x 240pixel display, a fast display update rate, up to 1000V independently floating isolated inputs, "connect-and-view" automatic triggering, a facility for measurement of effective output voltages of variable-speed motor drives and frequency invertors, a 5000-count true-RMS multimeter function, and optional FlukeView software for documenting, archiving and analysis.
