ScopeMeter

Speed, performance and analysis power

For more demanding applications, the ScopeMeter 190 Series high-performance oscilloscopes offer specifications found on top-end bench instruments. With up to 200 MHz bandwidth, 2.5 GS/s real-time sampling and a deep memory of 27,500 point per input, they're ideal for engineers who need the full capabilities of a high-performance oscilloscope in a handheld, battery powered instrument.

All Of This Power In The Palm Of Your Hand

ScopeMeter 190 Series has specifications you'll typically find on high-end bench oscilloscopes. They offer 200 MHz, 2.5 GS/s real-time sampling and advanced memory and triggering functions. They're rugged, compact and battery powered.

A choice of bandwidth

The ScopeMeter 190C and 190B Series offer up to 200 MHz bandwidth for capturing high-frequency signals found in today’s state-of-the-art electronics. For less demanding applications, there are also 100 MHz and 60 MHz models. You still get the same advanced functionality without paying for bandwidth you don't need.

Fast sampling to see what's really happening

With a maximum real-time sampling rate of 2.5 GS/s per input, you can see what really happens with 400 p resolution. Both inputs have their own digitizer, so you can simultaneously acquire two waveforms and analyze them with the highest resolution and detail. If an anomaly flashes by on the screen, just press the Replay button to see it again.

Connect-and-View™ Automatic triggering for an instant, stable display

Scope users know how difficult triggering can be. Wrong settings show unstable and sometimes wrong results. Fluke's unique Connect-and-View™ recognizes signal patterns, and automatically sets up correct triggering. It provides a stable, reliable and repeatable display of virtually any signal, including motor drive and control signals, without touching a button. Signal changes are instantly recognized and settings adjusted for, once again, a stable display. Benefit from the speed and convenience when measuring a number of test points in quick secession, unlike ordinary AutoSet/AutoRanging scopes.

Automatic capture and replay of 100 screens

Scope users know how frustrating it is to see a one-time anomaly flash by never to be seen again. Not with the ScopeMeter 190 Series! Now you can look back in time with a touch of the replay button. In normal use, the instrument continuously memorizes the last 100 screens. Each time a new screen is acquired, the oldest is discarded. At any moment you can "freeze" the last 100 screens and scroll through picture-by-picture or replay as a "live" animation. Cursors can be used for further analysis. You can even use the advanced trigger capabilities to capture up to 100 specific events. Two sets of 100 captured screens with individual time stamps can be stored for later recall or download to a PC.

Deep memory for high-resolution ScopeRecord™

The memory stores 27,500 points per input for high resolution recording of events up to 30 hours, and still captures fast intermittents and glitches as short as 50 nsec. This continuous roll mode also stores events like motion profiles, UPS, power supply and motor start-ups. And the 100X zoom your can look at the smallest of details, like individual power cycles. Two of these 27,500 point recordings can be stored for later analysis.

Advanced trigger modes

A wide choice of automatic and manual trigger modes gives you the flexibility to capture just about any signal you'll encounter. Connect-and-View triggering is ideal for fast and easy checking of multiple testpoints. The manual modes include time delay, video and pulse-width triggering. A fully isolated external trigger input is included for troubleshooting time relationships between two input signals synchronized to a third signal.

Analysis Power

For analysis of waveforms, ScopeRecord™ and TrendPlot™ recordings, the ScopeMeter features 26 automatic measurements, cursors, zoom and a real-time clock. The analysis can be made directly or later when back at the office. Up to 2 recordings and 10 scope screens can be stored for analysis, printout or download to a PC.



Advanced Waveform Mathematics

Advanced waveform mathematics can be used to show the difference between two signals using subtract or to display the power signal by multiplying Volt and Amp waveforms . A versus B (XY-mode) can be used for analyzing phase and frequency relations.

Use TrendPlot™ to help find intermittents, fast

The toughest faults to find are those once-in-a-while intermittents. They can be caused by bad connections, dust, dirt, corrosion or simply broken wiring or connections. Other factors, like line outages and sags, or the starting and stopping of a motor can also cause a machine to stop. You may not be around to see it - Fluke's ScopeMeter will. In this "paperless recorder" mode, you can plot the minimum and maximum peak values and average over time - up to 16 days. The two inputs can plot any combination of volts, amps, temperature, frequency and phase, with time and date stamp, to help lead you to the cause of those faults quickly.

Measure from mV to kV

The ScopeMeter 190 Series with three independently floating isolated inputs is safety certified for measurements in 1000V CAT II and 600V CAT III environments. And the standard probes cover a wide application range from mV to kV, making the ScopeMeter 190 ideal for micro electronics to electrical power applications.

A versatile test-tool

Just like the industrial ScopeMeter 123, the ScopeMeter 190 is a three-in-one instrument incorporating a scope, multimeter and paperless recorder. The rechargeable NiMH battery provides four hours of continuous operation, and takes just four hours to recharge. Battery saving and auto power down functions take you easily through the working day.
