THS700 Series

Handheld Battery Operated Oscilloscopes

The TekScope® THS700 Series Oscilloscope/DMM combines a full-featured real-time oscilloscope with a True RMS digital multimeter in rugged, battery-operated instruments. Scope and meter modes can operate simultaneously and independently on the same or separate signals. The high-resolution, backlit display and pop-up menus make it easy for users to take full advantage of the instrument's many features. These include cursors, video trigger, voltage and resistance measurements, and storage of waveforms, data, and instrument setups. In addition, they offer the most comprehensive triggering capabilities - external trigger and extensive triggering including delay, pulse width, and video.

The THS700A Series is ideal for electronic applications - at the bench or at the site.

The THS720P Oscilloscope/DMM includes features to address the needs of electrical/power electronics measurements.



The Only Safe Measurement Solution for Power Electronics

The THS720P TekScope IsolatedChannel™ Oscilloscope/DMM is ideal for electrical/power electronics applications.

The THS720P includes features specifically for electrical/power electronics measurements which allow testing and verifying correct operation of motors, checking transformer efficiency, verifying power-supply performance, and measuring the effect of neutral current. These features include harmonic analysis, power measurements and statistics and PWM motor drive triggering. It also contains the powerful features of a modern oscilloscope that enable troubleshooting and verification of complicated electronic control circuits controlling the high-voltage power-electronics circuitry.

The THS720P shares measurement features with the THS730A, THS720A Oscilloscope/DMMs, which are ideal for electronic applications.
