Tektronix THS720P Handheld Digital Oscilloscope

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.
