Fluke 190-202/S 2-channel hand-held oscilloscope, ScopeMeter® 190 series II, hand-held 4025554 データシート

ScopeMeter 190 Series II      Fluke Corporation  3

Automatic capture of 100 screens

When in oscilloscope mode, the instrument ALWAYS memorizes the last 100 screens—no specific user setup required. When an anomaly is 

seen, the REPLAY button can be pressed to review the full sequence of screen events over and over. Instrument can be set up for triggering on 

glitches or intermittent anomalies and will operate in “baby-sit” mode capturing 100 specified 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

Two sets of 100 screens each can be saved internally for later recall and analysis 

Direct storage of additional sets on external flash memory drive through USB host port

FFT – frequency spectrum analysis

Shows frequency content of oscilloscope waveform using Fast Fourier Transform
Window

Automatic, Hamming, Hanning or None

Automatic window

Digitally re-samples acquired waveform to get optimum frequency resolution in FFT resultant

Vertical scale

Linear / Logarithmic (in volts or amps)

Frequency axis

Frequency range automatically set as a 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

Pass/Fail Testing 

In waveform compare mode, the 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
