How To Capture Random Events Using The Instant Replay On A ScopeMeter® Test Tool
http://bit.ly/2H7fU8v
In this video, learn how to capture random events using triggering and view the results on instant replay with the Fluke 190 Series II Scopemeter® Portable Oscilloscope.
How to use Instant Replay:
1. Once your probe is connected to the ScopeMeter, touch the probe to create events
2. Configure time-base and attenuator settings
3. Press TRIGGER. Then press F3 for Manual to move the level up above the baseline
4. Press F4 for 'TRIGGER OPTIONS' and select Edge Trigger
5. Change trigger from 'Free Run' to 'On Trigger'
6. Close Window with F5
7. Once events have began, press the Instant Replay button and use the Previous/Next buttons to review events
8. Done
A faster sample rate and higher bandwidth means greater accuracy and clarity. The scope will capture and display unknown waveform shapes, amplitudes and any disturbances. In order to display at least the fifth harmonic component of a signal, a good rule of thumb is to select a scope with a bandwidth of at least five times the maximum clock rate of the device under test. The faster the sample interval, the more accurate and detailed the scope will display a signal edge (dV/dt) and peaks of any reflections or transients.
The Fluke ScopeMeter® 190 Series II combines the highest safety ratings and rugged portability with the high performance of a bench oscilloscope. Designed for plant maintenance engineers and technicians, these tough ScopeMeter test tools go into harsh, dirty, and hazardous industrial conditions to test everything from microelectronics to power electronics applications. Their sealed cases protect them from dust, water vapor, drips, humidity and airborne pollutants, ensuring reliable and accurate performance every time you need them.
TheFluke ScopeMeter® 190-504/S portable scopes are double-insulated four-channel floating oscilloscopes, safety rated for measurements in CAT III 1000V/CAT IV 600V environments.
