Product Description

The TIVM 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 electro-optic 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:

  • 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
