The Tektronix THS720P is a dual-channel handheld digital oscilloscope with integrated True RMS multimeter, engineered for field and bench troubleshooting in electrical and power electronics applications. It combines 100 MHz bandwidth, 500 MS/s sampling per channel, and isolated inputs rated to 600 VRMS CAT II, enabling simultaneous independent operation of oscilloscope and DMM functions. Advanced triggering—edge, pulse, video, and PWM motor drive—coupled with harmonic analysis to the 31st harmonic make it particularly suited for power quality assessment and motor drive diagnostics.
