See what’s really happening
 |
| High sampling rate gives you the required
resolution for detailed signal analysis | 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 (NEW)
 |
| Thanks to the deeper memory, very small parts of
the waveform can be studied in full detail using ‘zoom’.
| 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
 |
| Color traces and the high contrast display make
signal identification easy | 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
 |
| Digital persistence mode gives analog scope like
display of complex and modulated signals | The
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 a standard on all models
reveals signal changes instantaneously, useful for instance when making
adjustments to a system under test.
Advanced trigger modes
 |
| Pulse width triggering allows you to find
anomalies like missing pulses | 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.
(NEW)
 |
| Dual-slope triggering used to capture the
eyepattern on a digital datastream. | 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 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. Or you can 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™
 |
| Use the 27,500 points memory of the ScopeRecord
mode and zoom in for maximum detail | The
ScopeRecord memory stores 27,500 points per input or more, for high resolution
recording of events up to 48 hours, and captures fast intermit-tents and
glitches as short as 50 ns. This continuous roll mode stores, for example,
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!
 |
| Use Vpwm and measure effective voltage on motor
drive and frequency inverter outputs | The
ScopeMeter 190 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 ScopeMeter 190
Series ideal for micro-electronics to electrical power applications.
Analysis power
 |
| A wide variety of measurements can be made on
either Channel A or B | For analysis of waveforms,
ScopeRecord and TrendPlot recordings, the ScopeMeter 190 Series feature 30
automatic measurements, plus cursors, zoom and a real-time clock. The analysis
can be made directly or later when back in the office. Up to 2 recordings and 10
scope screens can be stored for analysis, print-out or download to a PC.
Frequency Spectrum Analysis (NEW)
 |
| Frequency Spectrum shows an overview of
frequencies contained in a signal. | 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
 |
| Pass/Fail testing of actual signal against a
reference template | ‘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
attend!
Cursor-limited automatic measurement (NEW)
 |
| The rms-value of the noise is measured on the part
of the waveform enclosed by the cursors. | 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.
... and there is more
- Variable gain on channel A helps you compare signals on the two
inputs. All inputs are safety certified for measurements in 1000 V CAT
II and 600 V
- The Vpwm measurement is for measuring the effective RMS output
voltage of variable speed motor drives and frequency inverters.
- Medical applications: For use on Medical Imaging Equipment and on
High-Resolution Video systems, an optional instrument configuration is
available for the Fluke 190 Series that supports measurement of

Use TrendPlot™ to help find
intermittents, fast
 |
| Cursors and zoom help you analyze the captured
TrendPlot | 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 - your Fluke 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 voltage,
current, temperature, frequency and phase - with time and date stamp -to help
lead you to the cause of those faults quickly.
