The Saker-MV ISOVP Probe enables high-voltage isolated measurements via fiber optic cables. Optical fiber isolation provides high-voltage safety and increased signal integrity due to absence of induced interference from external fields. This also allows for much higher common mode rejection as compared to conventional differential probes. The probe head can be remotely put in standby, or even powered off, for increased user safety and battery power savings. The user therefore does not need to reach into potentially hazardous high voltage areas to turn off the equipment when measurements are not needed. Up to 15m of fiber cable can be fitted between the probe head and receiver. The probe uses standard 1.5V AA batteries, with LEDs to indicate low battery conditions.
The ISOVP probe has been designed with minimal input capacitance to enable high frequency measurements. Typical analog optical links are prone to minor power variations due to connector mismatches, temperature drifts, and offsets. The Saker-MV probe uses a proprietary algorithm to calibrate the link and eliminate those errors. This increases overall accuracy as compared to other optical equipment and saves setup time.
The ISOVP probe can perform “hot” calibrations with no input disconnect, making it unnecessary to access the high voltage area during operation. This means saved time and increased user safety. Another useful feature puts the probe system in standby or turns off the probe head from the receiver so that the user does not need access to areas that can be at high voltage during tests. Most high-end oscilloscopes feature proprietary input connectors that force the user to choose the manufacturer’s supplied accessories of the scope. However, the ISOVP probe can be used with any 50-Ω terminated oscilloscope.
The probe head features a standard camera tripod mount thread. This makes it more convenient to place the probe inside tightly spaced cabinets or power modules in order to maintain proper clearance distances.
