Probe Assembly and Connection
1. Remove protective covers from the ber optic cable.
2. Connect the ber 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 t 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 micro-grippers.
Proper connection using stubs.

Optional Accessories
Attenuating Tips
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.

Do not expose the probe to static electricity, excessive
voltage or direct ultrasonic wave power.
Do not throw, hit, hammer or step on the probe, or otherwise
cause excessive impact or mechanical stress.
Do not reverse-charge or otherwise reverse the battery
polarity.
Do not charge the battery from a wall socket or cigarette
charger. Charge the battery only as instructed.
Do not use the probe if it is leaking or if you smell foul odors.
Read the manual before using the probe; read the charging
instructions before recharging the battery.
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 ber 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 unique common mode voltage range of the probe
system allows it to be used in the presence of high-
frequency/high-voltage common mode signals, but it is
important to observe all precautions while using it.
WARNING: RF burns or electric shock can occur when
using the HVFO108. The plastic case of the probe
head and tip shields do not provide safe isolation
from hazardous common mode voltages. Do not
access the probe while measuring signals in the RF
burn risk area.
Safety Symbols
These symbols appear on the probe or in documentation.
Terms
The terms isolated and electrically floating are used in
documentation to indicate measurements where there is
no direct conduction path to earth ground.

LASER RADIATION
DO NOT EXPOSE USERS O
F TELESCOPIC OPTICS
WARNING: The HVFO108 probe contains laser
sources, exposing which may cause laser burns.
Do not remove any covers from the transmitter or
receiver, or otherwise attempt to disassemble the
probe.
Using controls, adjustments or procedures other than
those specied in the product manual may result in
hazardous radiation exposure.
The probe uses optical bers within a single cable
between the transmitter and receiver. Therefore,
standard optical ber handling practices are required.
Avoid tight radius bends, crushing, crimping, twisting
or otherwise stressing the ber-optic cable.
Minimum cable radius bend is 65 mm; avoid making
loops smaller than 4 in (10.2 cm).
Before each use, inspect the cable for damage such
as tears and other defects.
