What could you do with four channels? Take multiple measurements simultaneously to track down the root cause of your most complex troubleshooting challenges. Analog Input Digital Feedback Analog/Digital Safety control Process/Display Output Condition 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 • Vpwm measurement to measure the effective voltage on drive outputs *Variable Speed Drive Power Supply Transducers Measurements' For industrial electronics, four channels allow you to perform three-dimensional testing, measuring input, output and feedback signals simultaneously.
