HVFO Probe System
HVFO108 Probe
The parts shown below are delivered standard with the HVFO108 in a soft carrying case.
The
amplifier/modulating transmitter
is a frequency modulating optical
transmitter integrated with a high-
performance electrical amplifier. The
transmitter is battery-powered, so
there is no direct connection from the
floating DUT, providing HV isolation
between the device under test (DUT)
and the grounded oscilloscope. The
battery is recharged through the same
USB Micro-B interface used to
connect the tip.
The
VersaLink (V-pin) 400/430 µm
fiber optic cable assembly
has low
loss and excellent transmission
characteristics, helping to optimize
the battery life of the transmitter. If
the attenuation in the fiber optic cable is too high, or the cable is damaged and not transmitting
properly, the probe will provide a warning to the user. A 1-meter cable is supplied; additional 1-
or 6-meter cables are available as optional accessories. The cable utilizes an Avago VersaLink
connector, enabling it to be interchanged with low cost, off-the-shelf fiber optic cables. Cables
longer than 6 meters may be sourced directly from the manufacturer (Industrial Fiber Optics,
), although HVFO108 accuracy specifications apply only to the
cables shipped in the original box.
Note:
If using a cable obtained from another vendor, perform the Performance Verification
procedure and calibration (p.23) with the new cable connected prior to operating the probe.
The
demodulating receiver
utilizes the ProBus interface to communicate tip attenuation value
and proper voltage scaling to the oscilloscope. With the ProBus interface, the HVFO probe
becomes an integral part of the measuring instrument. Power is provided to the receiver
through the signal interface, so there is no need for a separate power supply or batteries.
Also included are a
USB-A – USB Micro-B cable
and
E-Z Micro-Grippers
(1 set of 3).
