Fluke 199C ScopeMeter
 See More, Fix More with Color
With the high performance specifications usually found on bench oscilloscopes, plus the large high resolution color screen, the new Digital Persistence
mode, and a much faster display update rate, the Color ScopeMeter Series brings a new dimension to working in the field.
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!
Deeper waveform acquisition memory
The waveform memory of all oscilloscopes in both the 190B and 190C Series has been enlarged to allow as many as 3000 samples per channel to be acquired.
This is 1800 samples more than before, giving much greater waveform resolution.
You can use the ZOOM function to find tiny details in a long waveform, for example, the color burst in a video signal or a single impulse in a complex data-stream.
All models also allow the high-resolution waveforms to be transferred to a PC for later detailed analysis using FlukeView ScopeMeter software.
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.
Dual-Scope Triggering
Two new modes – ‘n-cycle triggering’ and ‘dual-slope triggering’ – have been added to the Fluke 190C Series to help you isolate the phenomena of interest.
N-cycle triggering ensures you get a stable ‘live’ image of a signal, for example, in frequency dividers and clocked (synchronous) digital systems, or to synchronize on bursts of pulses.
Dual-slope triggering enables the oscilloscopes to trigger on both rising and falling edges alike.
This means that any edge in the signal will act as trigger event and initiate a new waveform acquisition, a most useful capability when making eye-patterns from digital data-streams, or in conjunction with single-shot phenomena.
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.
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.
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.
Frequency Spectrum Analysis
All 190C Color ScopeMeters now include Frequency Spectrum Analysis functionality based on Fast Fourier Transformation (FFT) analysis as a standard feature.
This makes it possible for you to identify the individual frequency components contained in a signal.
The spectrum analysis function is also handy to reveal the effects of vibration, signal interference or crosstalk.
An automatic window function assures optimal windowing, although you may manually select your preferred time window.
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!
Cursor-limited automatic measurement
Automatic power and Vrms-measurements can now be performed on a specific, user identified portion of the waveform using the cursors of the Fluke 190C to define the time-window of interest.
In this way, the Color ScopeMeter can measure the power within a specified time span, or the rms-value of a voltage during a dedicated period of time
Many more new functions
- Variable gain on channel A helps you compare signals on the two inputs.
- The Vpwm measurement is for measuring the effective rms output voltage of variable speed motor drives and frequency inverters.
- The high-sensitivity setting of 2 mV/div allows for measurements on low-level signals, that are hard to make with the average oscilloscope. (Fluke 190C)
- For medical imaging diagnostics or high resolution video applications, an optional configuration is available with current over time (mAs), high-resolution video triggering (up to 2800 lines) and more.
