Bandwidth considerations
Bandwidth considerations
The dominant probe limitation to system bandwidth is its input capacitance,
assuming that the high-frequency compensation adjustments have been made.
The displayed bandwidth of any measurement system using an oscilloscope and
probe is determined by four factors: probe input capacitance, source impedance,
source bandwidth, and oscilloscope bandwidth.
1170 Series Probes Selection Guide
NOTE: An E2697A 1 MΩinput adapter is required to use this probe with a 50 Ω
oscilloscope. The E2697A includes one 10073C general purpose 100 MHz, 10:1
passive probe.

Safety considerations
Safety considerations
WARNING SHOCK HAZARD!
These probes are designed for use with oscilloscopes that have a common
terminal at GROUND POTENTIAL (in accordance with OSHA requirements and
the National Electric Code). Exposed metallic surfaces of the probe and the
oscilloscope MUST BE GROUNDED. Failure to ground the common terminal
during certain applications, such as those requiring the oscilloscope to be
powered from an external battery, might expose the operator to an electrical
shock hazard that could be lethal (depending on voltage and current
conditions.)
Cleaning the probe
If the 1170 Series Probe requires cleaning, disconnect it from all power sources
and clean it with a soft cloth dampened with a mild soap and water solution.
Make sure the probe is completely dry before reconnecting it to a power source.

Compensation adjustments
Compensation adjustments
You can adjust the probes for both low-frequency compensation and high-
frequency compensation. Low-frequency compensation is an operating
adjustment.
Adjusting low-frequency compensation
Before you can have a flat frequency response when using a compensated passive
divider probe, you must compensate the probe’s cable capacitance and
oscilloscope input capacitance to optimize the step response for flatness. You
should compensate your probe to match its characteristics to the oscilloscope.
A poorly compensated probe can introduce measurement errors.
1Connect the probe from the appropriate oscilloscope channel to
the front-panel probe adjust signal terminal [ ] on the oscilloscope.
You can attach the probe with the holes in the probe body facing up to allow
adjustment.
2Press Autoscale.
3Using the wide end of the supplied screwdriver tool, set the low-
frequency compensation adjustment on the probe for the flattest pulse
possible as shown below.
Low-Frequency Adjustment and Waveforms
When to Adjust the Probe Compensation
Low-frequency compensation is adjusted when you first connect the probe to the
oscilloscope. Probe and channel-to-channel compensation will usually hold over
all of the attenuator ranges when used with the recommended Agilent Technologies
Oscilloscope. For more information, see “Safety considerations” on page 10

nect the protective earth
terminal of the instrument
to the protective conduc-
tor of the (mains) power
cord. The mains plug shall
only be inserted in a
socket outlet provided
with a protective earth
contact. You must not
negate the protective
action by using an exten-
sion cord (power cable)
without a protective con-
ductor (grounding).
Grounding one conductor
of a two-conductor outlet
is not sufficient protection.
• Only fuses with the
required rated current,
voltage, and specified
type (normal blow, time
delay, etc.) should be
used. Do not use repaired
fuses or short-circuited
fuseholders. To do so
could cause a shock or
fire hazard.
• If you energize this
instrument by an auto
transformer (for voltage
reduction or mains isola-
tion), the common termi-
nal must be connected to
the earth terminal of the
power source.
• Whenever it is likely that
the ground protection is
impaired, you must make
the instrument inopera-
tive and secure it against
any unintended operation.
• Service instructions are
for trained service person-
nel. To avoid dangerous
electric shock, do not per-
form any service unless
qualified to do so. Do not
attempt internal service or
adjustment unless another
person, capable of render-
ing first aid and resuscita-
tion, is present.
• Do not install substitute
parts or perform any
unauthorized modification
to the instrument.
• Capacitors inside the
instrument may retain a
charge even if the instru-
ment is disconnected from
its source of supply.
• Do not operate the
instrument in the pres-
ence of flammable gasses
or fumes. Operation of
any electrical instrument
in such an environment
constitutes a definite
safety hazard.
• Do not use the instru-
ment in a manner not
specified by the manufac-
turer.
To clean the instrument
If the instrument requires
cleaning: (1) Remove
power from the instru-
ment. (2) Clean the exter-
nal surfaces of the
instrument with a soft
cloth dampened with a
mixture of mild detergent
and water. (3) Make sure
that the instrument is
completely dry before
