find on high-end bench oscilloscopes.
They offer up to 200 MHz bandwidth for capturing high frequency
signals, as found in today’s state-of-the-art electronics, 2.5 GS/s
real-time sampling and advanced memory and triggering functions.

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!
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.
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!
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.
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.
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.
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!
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.
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.
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 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!
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.

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.
The high-sensitivity setting of 2 mV/div allows for measurements on
low-level signals, that are hard to make with the average oscilloscope.
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
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.
