Silicon Carbide Suitable
The new HVFO108, with 150 MHz
of bandwidth, is perfect for device
research engineers designing Silicon
and Silicon Carbide devices, and
system development engineers
incorporating Silicon Carbide devices.
Optical Isolation is Best
Optical isolation between the probe
tip and the oscilloscope input ensures
safety against dangerous high voltage
levels, reduces adverse DUT loading,
provides faithful pulse response, and
increases measurement condence.
Compact, Simple, Affordable
The HVFO108 ts into tight spaces
as well as tight budgets, without
sacricing performance.
Superior Noise Rejection
High CMRR (140 dB) provides more
accurate representation of the
measured signal despite the presence
of high dV/dt or dA/dt events elsewhere
in the circuit. The test lead is optimized
to limit loop inductance and radiated
pickup. Tip attenuations are optimized
for a wide range of signal amplitudes.
Applications
The HVFO108 is ideal for upper-side
gate drive measurements, floating
control signal or sensor voltage
measurements, EMC/EFT/ESD/
RF immunity testing and system
optimization, or any small signal
measurements with high common-
mode voltage.
The new HVFO108, with 150 MHz of bandwidth, is suitable for both
Silicon and Silicon Carbide designs. It is designed to measure small
signals oating on an HV bus and delivers excellent performance, has
high CMRR, and provides optical isolation to reduce DUT loading.
