What could you
do with four
channels?
Take multiple measurements
simultaneously and track down the
root cause of your most complex
troubleshooting challenges.
Easily diagnose timing-related issues
with multiple signals
•
Real-time inspection of multiple related
signals simultaneously
•
Measure a combination of input and output
signals and system safety interlocks and
feedback loops
Find problems in industrial systems
including:
•
Circuit voltage/current overloading
•
Attenuation/input impedance mismatch
•
Signal fluctuation/drift
•
Conditioning circuits signal integrity
•
Test point verification for critical signals
•
Input/output/feedback timing issues
•
Induced noise and disturbances
•
Random shutdowns/reset
Diagnose VSDs or power inverters and
converters
•
Harmonics, transients and loads in three-
phase power input
•
Troubleshoot dc to ac converters for faulty
control circuits or output IGBT gate stages
•
Cable interface—test PWM output for reflec-
tions and transients
In three-phase systems like variable speed drives, UPS or
back-up generators, use four channels to diagnose power
input, dc to ac converters, or cable interface problems.
For industrial electronics, four channels allows you to
perform three-dimensional testing, measuring input,
output and feedback signals simultaneously.
