Probe Assembly and Connection
1. Remove protective covers from the fiber optic cable.
2. Connect the fiber optic cable to the receiver and
transmitter. You will hear a "click" when properly
inserted.
3. Connect the tip to the transmitter USB Micro-B port.
4. Press the demodulating receiver box onto the
oscilloscope ProBus interface.
CAUTION: Once a tip is connected, the transmitter
will begin to consume battery power. Do not leave
tips connected unless the probe is in use.
Connecting Tips
For accurate measurements, connect all three input
leads to the test circuit.
1. Connect the blue Signal lead to voltage (Vs).
2. Connect the green Reference and black Shield leads
to the floating board reference (Vcm).
Tip lead sockets fit well onto 22AWG wires or 0.100"
pitch pin headers. Micro-grippers provide two
connections, so Reference and Shield can be connected
to one micro-gripper.
CAUTION: Reference and Shield wires are
electrically connected inside the tip. Failure to
connect them to the same potential may damage
the DUT and/or probe.
Proper connection using stubs.
Proper connection using micro-grippers.
The HVFO108 probe is a high-voltage, fiber-optically isolated
probe designed to measure small signals floating on an HV
bus in power electronics designs, or for EMC, EFT, ESD, and
RF immunity testing.

Compatibility
Use only with compatible Teledyne LeCroy instruments
running Windows 10 and 64-bit MAUI firmware, v.9.2.x.x or
higher. For a current list of compatible instruments, visit:

Standard Parts
Amplifier/Modulating Transmitter
Battery-powered, frequency modulating optical transmitter
transmits signal and data across a fiber optic cable. ~6 hours
of use.
De-modulating Receiver
Receiver de-modulates optical signal into an electrical output
to the oscilloscope with correct voltage scaling. ProBus
connector.
VersaLink (V-pin) 400/420 Fiber Optic Cable
1 m fiber optic cable connects transmitter and receiver.
EZ Micro-Grippers
1 set of 3 micro-grippers for connecting to IC legs, pins, etc.
Battery Charging Cable
USB micro-B-to-A cable for recharging the transmitter.
Soft Storage Case
Soft case with custom foam insert.
Cable Status and Battery
When the probe is connected to an oscilloscope, the
CHnHVFO108 Probe dialog is displayed behind the channel
setup dialog.
Cable Status indicates general quality of the fiber optic cable.
If "Poor," the cable is near end of life and should be replaced.
Battery indicates remaining battery life. 100% is about 6 hrs.
of operation. LEDs on the transmitter and receiver body also
indicate when the battery requires recharging.
Recharging the Battery
Ambient temperature during charging should be 0° to 40° C.
CAUTION: Recharge temperature range is lower than
the operating range of the probe.
1. Remove the tip.
2. Insert the charging cable into the Micro-B port on the
transmitter.
3. Connect the charging cable to a USB port on the
oscilloscope or PC, or else to a USB charger.
CAUTION: Make sure the source is powered on or the
battery will continue discharging.
An LED will light while the battery is recharging.
Recharge time is approximately 5 hours if connected to an
oscilloscope (or PC), or 2.5 hours if using a USB charger.
Battery Safety
The probe amplifier/transmitter contains a Lithium polymer
battery. To avoid personal injury or property damage due to
electrical bursts, smoke, fire or explosions, follow UL1642
safety requirements, especially those listed here:
Do not disassemble or modify the probe or the internal
battery.
Do not attempt to replace the battery. Return the probe to
Teledyne LeCroy Service if the battery needs to be replaced.
Do not heat/incinerate the probe, use it near heat sources or
in excessively hot environments, or solder near the battery.
Do not place the probe in a microwave or high-pressure
container when handling or using it.
Optional Accessories
Attenuating Tips
HVFO100-1X-TIP-U
HVFO100-5X-TIP-U
HVFO100-10X-TIP-U
HVFO100-20X-TIP-U
HVFO100-40X-TIP-U
At least one 1x, 5x, 10x, 20x or 40x optional attenuating
tip is required for operation. Tips have a noise immune
coaxial cable to connect to voltage, with separate
connections for reference and ground.
Safety Derating for Accessories
The measurement terminals of the probe as well as all
accessories are to be used only for measurements on
circuits not directly connected to the mains.
WARNING: The probe and accessories are not rated for
measurements within Measurement Categories (CAT)
II, III or IV. The Measurement Category is the lower of
the Measurement Categories of the probe or accessory.
Do not exceed the CAT, voltage or current rating of the
lowest rated individual component.
Maximum input voltage is derated according to
the following table when using the probe with the
corresponding tip.
HVFO100-1X-TIP-U ±1 V (DC + Peak AC)
(5 V maximum non-destruct)
HVFO100-5X-TIP-U ±5 V (DC + Peak AC)
(25 V maximum non-destruct)
HVFO100-10X-TIP-U ±10 V (DC + Peak AC)
(50 V maximum non-destruct)
HVFO100-20X-TIP-U ±20 V (DC + Peak AC)
(100 V maximum non-destruct)
HVFO100-40X-TIP-U ±40 V (DC + Peak AC)
(100 V maximum non-destruct)
