In place of the cancelled International Power Modulator and High Voltage (IPMHVC) conference, GMW invites you to view our Virtual Exhibition at your convenience. Our experts in RF over Fiber-Optic Links and Voltage Isolated High Current Measurement are available for consultation and discussion.
Sentinel 3 Intelligent Fiber Optic Links
Sentinel 3 is the world’s most advanced RF over fiber test and measurement system for:
- EMP test and EMC conformance
- HIRF aircraft clearance
- Simulated lightning testing
- Impulse, time domain and NEMP testing
- Low and high level swept frequency coupling measurements
Sentinel 3 users can quickly create an application to control Sentinel 3 within the LabVIEW environment. They can create repeatable and consistent tests that improve data accuracy by removing the need for manual processing and, in turn, save time. Further, LabVIEW allows users to select the Automatic Gain Control (AGC) and temperature compensation, as well as sync the clock with a PC.

CWT Clip-on AC Rogowski Current Probes
PEM CWT Clip-on AC Current Probes have frequency response recently extended to 50MHz (7ns rise-time), current ranges to over +/-1MA and Coil lengths to over 30m. Applications range from ac power measurements, through power semiconductor switching waveform characterization to lightning current discharge monitoring. The MiniHF versions include electrostatic shielding of the Rogowski Coil to reduce capacitive coupling from very high dV/dt on the primary conductor and extend the frequency response to 50MHz.
