Environmental Conditions
Overvoltage Category
This product is intended to be powered by MAINS that comply to Overvoltage Category II, which is
typical of cord-and-plug connected equipment.
Pollution Degree
The 9000 Series oscilloscope may be operated in environments of Pollution Degree 2 (or Pollution
Degree 1).
Pollution Degree Definitions
Pollution Degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no
influence. Example: A clean room or climate controlled office environment.
Pollution Degree 2. Normally only dry non-conductive pollution occurs. Occasionally a temporary
conductivity caused by condensation may occur. Example: General indoor environment.
Pollution Degree 3: Conductive pollution occurs, or dry, non-conductive pollution occurs which
becomes conductive due to condensation which is expected. Example: Sheltered outdoor environment.
Measurement Category
Measurement Category
The Keysight Infiniium 9000 Series oscilloscopes are not rated for Measurement Category II, III, or IV.
Measurement Category Definitions
Measurement Category II is for measurements performed on circuits directly connected to the low
voltage installation. Examples are measurements on household appliances, portable tools and similar
equipment.
Measurement Category III is for measurements performed in the building installation. Examples are
measurements on distribution boards, circuit-breakers, wiring, including cables, bus-bars, junction
boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other
equipment, for example, stationary motors with permanent connection to the fixed installation.
Measurement Category IV is for measurements performed at the source of the low-voltage installation.
Examples are electricity meters and measurements on primary overcurrent protection devices and ripple
control units.
Transient Withstand Capability
The maximum transient withstand capability of this instrument is not specified. Do not apply more than
5 volts rms at the oscilloscope’s vertical input BNC connectors.
WARNING SAFETY CLASS 1 PRODUCT
This is a Safety Class 1 Product (provided with a protective earth ground incorporated in the power
cord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact.
Any interruption of the protective conductor inside or outside of the product is likely to make the product
dangerous. Intentional interruption is prohibited.

Calibration

14
To run the self calibration
The self calibration uses signals generated in the oscilloscope to calibrate channel sensitivity, offsets,
and trigger parameters. You should run the self calibration
• yearly, or according to your periodic needs,
• when you replace the acquisition assembly or acquisition hybrids,
• when you replace the hard drive or any other assembly,
• when the oscilloscope’s operating temperature (after the 30-minute warm-up period) is more than
±5°C different from that of the last calibration.
Equipment Required
Self calibration
1Let the oscilloscope warm up before running the self calibration.
The self calibration should only be done after the oscilloscope has run for 30 minutes at ambient
temperature with the cover installed. Calibration of an oscilloscope that has not warmed up may result
in an inaccurate calibration.
2Pull down the Utilities menu and select Calibration.
3Click the check box to clear the Cal Memory Protect condition.
You cannot run self calibration if this box is checked. See Figure 1.
Let the Oscilloscope Warm Up Before Adjusting
Warm up the oscilloscope for 30 minutes before starting calibration procedure. Failure to allow
warm up may result in inaccurate calibration.

Calibration time
It will take approximately 1 hour to run the self calibration on the oscilloscope, including the time
required to change cables from channel to channel.

4Click Start, then follow the instructions on the screen.
The routine will ask you to do the following things in sequence:
aDecide if you want to perform the Time Scale Calibration. Your choices are:
• Standard Calibration - Time scale calibration will not be performed. Time scale calibration
factors from the previous time scale calibration will be used and the 10 MHz reference signal
will not be required. The remaining calibration procedure will continue.
• Standard Calibration and Time Scale Calibration - Performs the time scale calibration. This
option requires you to connect a 10 MHz reference signal to channel 1 that meets the following
specifications. Failure to use a reference signal that meets this specification will result in an
inaccurate calibration.
• Standard Calibration and Reset Time Scale Calibration - Factory time scale calibration factors
will be used. The 10 MHz reference signal will not be required. The remaining calibration
procedure will continue.
bDisconnect everything from all inputs and Aux Out.
cConnect the 50 ΩBNC cable from Aux Out to channel 1.
dConnect the 50 ΩBNC cable from Aux Out to each of the channel inputs as requested.
eFollow the directions for calibrating the digital channels (MSO models only).
fA Passed/Failed indication is displayed for each calibration section. If any section fails, check
the calibration cables and run the oscilloscope Self Test in the Utilities menu. Page 87 also has
a little section on what to do if a self cal fails in terms of replacing assemblies.
5After the calibration procedure is completed, click Close.

Testing Performance

This section documents performance test procedures. Performance verification for the products covered
by this manual consists of three main steps:
• Performing the internal product self-tests to ensure that the measurement system is functioning
properly
• Calibrating the product
• Testing the product to ensure that it is performing to specification
Performance Test Interval
The procedures in this section may be performed for incoming inspection and should be performed
periodically to verify that the oscilloscope is operating within specification. The recommended test
interval is once per year or after 2000 hours of operation. Performance should also be tested after repairs
or major upgrades.
Performance Test Record
A test record form is provided at the end of this section. This record lists performance tests, test limits
and provides space to record test results.
Test Order
The tests in this section may be performed in any order desired. However, it is recommended to conduct
the tests in the order presented in this manual as this represents an incremental approach to performance
verification. This may be useful if you are attempting to troubleshoot a suspected problem.
Test Equipment
Lists of equipment needed to conduct each test are provided for each test procedure. The procedures are
written to minimize the number and types of test equipment and accessories required. The test equipment
in these lists are ones that are currently available for sale by Keysight at the time of writing this document.
In some cases, the test procedures use features specific to the test equipment in the recommended
equipment list. However, with some modification to the test procedures, equipment, cables and
accessories that satisfy the critical specifications in these lists may be substituted for the recommended
models with some modification to the test procedures.
Contact Keysight Technologies for more information about the Keysight products in these lists.
