Number of inputs 2 plus external trigger. All inputs isolated from
each other and ground.

5 mV/div to 100 V/div (Fluke 190B Series)
Normal/Invert On both input channels; switched separately
Variable Attenuator Variable Gain on input channel A
Input voltage 1000V CAT II, 600 V CAT III rated - See ‘general
specifications’ for further details.

Accuracy ± (1.5% of reading + 0.04 x range/div)
Input impedance 1 MΩ ± 1% // 15 pF ± 2 pF

Maximum record length 3000 points per input in Scope-mode;
27,500 points per input in ScopeRecord™ roll
mode (5 ms/div … 2 min/div)
Accuracy ± (0.01% of reading + 1 pixel)
Glitch capture 50 nsec (5 µsec/div to 1 min/div)
DISPLAY AND ACQUISITION
Visible screen width 12 divisions in scope mode
Waveform Mathematics A+B, A-B, A*B, all with user selectable scaling
of resultant; A versus B (X-Y-mode); Frequency
Spectrum using FFT analysis (190C only).
Acquisition modes Normal, auto, single shot, ScopeRecord™, roll,
glitch capture, waveform compare, waveform
compare with automatic “Pass / Fail testing” (in
199C and 196C only)
TRIGGER AND DELAY
Source Input A, input B, external trigger input. All input
references isolated from each other and from
ground.
Modes Automatic Connect-and-View™, free run, single
shot, edge, delay, video, video line, selectable
pulsewidth, dual slope (190C only), N-cycle
(190C only)
Connect-and-View™ Advanced automatic triggering that recognizes
signal patterns, automatically sets up and conti-
nuously adjusts triggering, time base and ampli-
tude. Automatically displays stable waveforms
of complex and dynamic signals like motor drive
and control signals. Can be switched off if so
desired.
Video triggering NTSC, PAL, PAL+, SECAM. Includes field 1, field
2 and line select.
Pulse width triggering Pulse width qualified by time. Allows for trigge-
ring <t, >t, =t, =/ t, where t is selectable in
minimal steps of 0.01 div or 50 nsec
Time delay 1 full screen of pre-trigger view or up to 100
screens (=1200 divisions) of post-trigger delay.
Dual slope triggering Both rising and falling transitions, when
crossing the trigger level, initiate an acquisition
(190C only)
N-cycle triggering Triggers on N-th occurrence of a trigger event;
N to be set in the range 2 to 99 (190C only).
AUTOMATIC CAPTURE OF The instrument ALWAYS memorizes the last
100 SCREENS 100 screens (no user setup required). When an
anomaly occurs on screen, the REPLAY button
can be pressed to review the full screen
sequence over and over. Instrument can be
set up for triggering on glitches or intermittent
anomalies and will operate in “baby-sit” mode
and will capture 100 events.
Replay Manual or continuous replay. Displays the
captured 100 screens as a “live” animation, or
under manual control. Each screen has date-
and time-stamp.
Replay storage Up to 2 sets of 100 screens each can be saved
for later recall and analysis.
FFT - FREQUENCY SPECTRUM ANALYSIS (190C only)
Shows frequency content of oscilloscope
waveform using Fast Fourier Transform
Window Automatic, Hamming, Henning or None
Automatic Window Digitally re-samples acquired waveform to get
optimum frequency resolution in FFT resultant
Vertical Scale Linear / Logarithmic, in volts
Frequency Axis Logarithmic; frequency range automatically set
as function of timebase range of oscilloscope
WAVEFORM COMPARE AND PASS/FAIL TESTING
Waveform compare Provides storage and display of a reference
waveform for visual comparison with newly
acquired waveforms. Reference is derived from
an acquired waveform and can be modified in
the ScopeMeter or externally using FlukeView
Software.
Pass/Fail Testing (199C, 196C) In waveform compare mode, the Color
ScopeMeter can be set up to store only
matching (“Pass”) or only non-matching (“Fail”)
acquired waveforms in the replay memory bank
for further analysis.
