HIGH VOLTAGE FIBER OPTICALLY-ISOLATED PROBES
Teledyne LeCroy
High Voltage Fiber
Optically-isolated Probe
Model Number:
HVFO103
Key Features
Applications
•
Upper-side gate drive signal measurements
•
Floating control signal or sensor voltage measurements
•
EMC, EFT, ESD, and RF immunity testing and system optimization
•
Any small signal measurements with high common-mode voltage
50 MHz and 60 MHz bandwidth
35 kV common-mode voltage rating (ber optic isolation)
Superior Noise and Rejection
•
140 dB CMRR
•
Low loop inductance
•
Low attenuation
Reduced DUT loading, better pulse response compared to conventional
HV differential probes
Selectable tips from ±1V to ±40V
Eliminates need to “oat” the oscilloscope
ProBus-compatible with many Teledyne LeCroy oscilloscopes
The HVFO is an affordable, optimally designed probe for measurement of small
signals floating on an HV bus in power electronics designs or for EMC, EFT, ESD,
and RF immunity testing sensor monitoring. It far surpasses the measurement
capabilities and signal delity of both conventional HV differential probes and
acquisition systems that rely on galvanic high voltage isolation. Furthermore,
it mitigates the need to rely on dangerous test setups that require floating the
oscilloscope and probe.
