Thanks to the deeper memory, very small parts
of the waveform can be studied in full detail
using ‘zoom’.
Digital Persistence mode gives analog
scope-like display of complex and modulated
signals.
Frequency Spectrum shows an overview of
frequencies contained in a signal.
Dual-slope triggering used to capture the
eye-pattern on a digital datastream.

Deeper waveform acquisition memory
The waveform memory of all oscilloscopes
in the190C Series has been enlarged to
allow as many as 3000 samples per
channel to be acquired. 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.
See dynamic signal behavior
instantaneously
The Digital Persistence mode 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 times –
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
The ScopeMeter 190C Series greatly
simplifies triggering with Connect-and-
View™ automatic 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 a
trigger event and initiate a new
waveform acquisition, a most useful
capability when making eye-patterns
from digital datastreams, or in conjunction
with single-shot phenomena. However,
manual triggering is sometimes required.
Manual modes include edge, 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.
Frequency Spectrum Analysis
All 190C Color ScopeMeter models now
include Frequency Spectrum Analysis
functionality based on Fast Fourier
Transformation (FFT) analysis as a
standard feature. This enables you to
identify the individual frequency
components contained in a signal.
The spectrum analysis function is also
handy for revealing the effects of
vibration, signal interference or crosstalk.
An automatic window function assures
optimal windowing, although you may
manually select your preferred time
window.
