60MHZ B/W USA ScopeMeter

For the more demanding applications, the ScopeMeter 190 Series high-performance oscilloscopes offer specifications usually 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 points per input they’re ideal for engineers who need the full capabilities of a high-performance oscilloscope in a handheld, battery powered instrument.

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.

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 ps 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. And thanks to the wider screen, you will always see a 12 divisions time window - giving a far better overview of what's happening both before and after the trigger event!


Easier identification of traces, everywhere

The full-color display makes identification of individual waveforms easier, particularly when displaying large amplitude or multiple overlapping waveforms on screen. On-screen color labels, measurements and warnings are clearly linked to specific waveforms. The bright, high-contrast display allows for clear reading under varying light conditions. And still a 4-hour battery operation time is assured!

See dynamic signal behavior instantaneously

The Digital Persistence mode (Fluke 190C) helps to find anomalies and to analyze complex dynamic signals by showing the waveforms amplitude distribution over time. Digital Persistence uses multiple intensity levels and user selectable decay time - it's as if you're looking at the display of an analog, real time oscilloscope! The fast display update rate that's standard on all models reveals signal changes instantaneously, useful for instance when making adjustments to a system under test.

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 test-points. 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.

Waveform Pass/Fail Testing

"Waveform reference" allows an acquired trace to be stored and designated "reference trace" for visual comparisons, or it can be used as the reference for automatic "Pass/Fail" testing (190C). Up to 100 individually matching ("Pass") or non-matching ("Fail") waveforms can be stored in the replay memory, allowing you to monitor your system's behavior over a long period of time, without the need for you to be present!

Automatic capture and replay of 100 screens

Scope users know how frustrating it is to see an 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.

Use TrendPlot™ to help find intermittents, fast

The toughest faults to find are those that happen only once in a while - intermittents. They can be caused by bad connections, dust, dirt, corrosion or simply broken wiring or connectors. 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 22 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.

Deep memory for high-resolution ScopeRecord™

The ScopeRecord memory stores 27,500 points per input or more, for high-resolution recording of events up to 48 hours, and captures fast intermittents and glitches as short as 50 ns. This continuous roll mode, for example, stores events like motion profiles, UPS, power supply and motor start-ups. All models also have a "Stop-on-Trigger" in the ScopeRecord mode. This allows the ScopeMeter to store waveform data until the instrument is triggered or until a repetitive trigger signal is interrupted. This way, the instrument will, for example, automatically recognize a power failure and store the waveform data preceding it. And with 100 x zoom, you can look at the smallest details, like individual power cycles. Two of these 27,500 point recordings can be stored for later analysis.

Analysis power

For analysis of waveforms, ScopeRecords and TrendPlot recordings, the ScopeMeter 190C and 190B features 30 automatic measurements, cursors, zoom and real-time clock. The analysis can be made directly or later when back in the office. Up to two recordings and 10 scope screens can be stored for analysis, print-out or download to a PC.

Measure from mV to kV - fully isolated and safely!

The ScopeMeter 190C and 190B series have three independently floating isolated inputs. While conventional oscilloscopes can only make measurements referenced to the line power ground, measurements on each of the Fluke ScopeMeter 190 series inputs can be referenced to a different "low" level. This enables measurements in mixed circuits having different ground references, and also eliminates the risk of accidental ground short circuits. All inputs are safety certified for measurements in 1000 V CAT II and 600 V CAT III environments. And the standard probes cover a wide application range from mV to kV, making the 190C and 190B ScopeMeter ideal for micro electronics to electrical applications.
