The Tektronix TIVM and TIVH Series IsoVu™ Measurement Systems offer galvanically isolated measurement solutions for accurately resolving high bandwidth, differential signals up to ±2500 V in the presence of large common mode voltages with the best in class common mode rejection performance across its bandwidth. Applications Half/Full Bridge designs using GaN, SiC, IGBTs Floating measurements Power Converter design Power Device evaluation Switching Power Supply design Inverter design Motor Drive design Electronic Ballast design EMI ESD Current shunt measurements Remote probing capability Product Description The TIVM and TIVH Series (IsoVu) products can be used on most Tektronix oscilloscopes with the TekVPI interface and on MSO/DPO70K series oscilloscopes with the TCA-VPI50 adapter. IsoVu utilizes an electrooptic sensor that converts the electrical signal from the sensor tip cables to an optical signal, which electrically isolates the device-under-test from the oscilloscope. IsoVu incorporates four separate lasers, an optical sensor, five optical fibers, and sophisticated feedback and control techniques. The sensor head, which connects to the test point, has complete electrical isolation and is powered over one of the optical fibers (No batteries required). IsoVu is an ideal solution for users making the following measurements: Features and benefits • Bandwidths from DC to 1 GHz • 100 Million to 1 (160 dB) Common Mode Rejection from DC up to 1 MHz 10,000 to 1 (80 dB) Common Mode Rejection at 1 GHz 60 kV peak Common Mode Voltage Up to ±2500 V Differential (DC + pk AC) Up to ±2500 V offset range Output clamping Safety certified DC and AC input coupling • Differential measurements in the following conditions: Complete galvanic isolation is required High common mode voltage High frequency common mode interference High frequency measurements • Measurements in high EMI environments • EMI compliance testing • ESD testing
