Important safety information
To avoid fire or personal
injury
Ground the product. This product is indirectly grounded through the grounding
conductor of the mainframe power cord. To avoid electric shock, the grounding
conductor must be connected to earth ground. Before making connections to the
input or output terminals of the product, ensure that the product is properly
grounded. Do not disable the power cord grounding connection.
Power disconnect. The power cord disconnects the product from the power
source. See instructions for the location. Do not position the equipment so that it
is difficult to operate the power cord; it must remain accessible to the user at all
times to allow for quick disconnection if needed.
Connect and disconnect properly. Do not connect or disconnect probes or test
leads while they are connected to a voltage source. Use only insulated voltage
probes, test leads, and adapters supplied with the product, or indicated by
Tektronix to be suitable for the product.
Observe all terminal ratings. To avoid fire or shock hazard, observe all rating and
markings on the product. Consult the product manual for further ratings
information before making connections to the product.
Do not apply a potential to any terminal, including the common terminal, that
exceeds the maximum rating of that terminal.
Do not operate without covers. Do not operate this product with covers or panels
removed, or with the case open. Hazardous voltage exposure is possible.
Do not operate with suspected failures. If you suspect that there is damage to this
product, have it inspected by qualified service personnel.
Disable the product if it is damaged. Do not use the product if it is damaged or
operates incorrectly. If in doubt about safety of the product, turn it off and
disconnect the power cord. Clearly mark the product to prevent its further
operation.
Examine the exterior of the product before you use it. Look for cracks or missing
pieces.
Use only specified replacement parts.
Wear eye protection. Wear eye protection if exposure to high-intensity rays or
laser radiation exists.
Do not operate in wet/damp conditions. Be aware that condensation may occur if a
unit is moved from a cold to a warm environment.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry. Remove the input signals before you clean
the product.

The unfiltered frequency response approximates a 4th order Bessel-Thomson curve with a -3 dBe
frequency of 21 GHz. The response on a TekConnect channel is altered slightly relative to the
response on an ATI channel. This is due to microwave characteristics of the coaxial cable
connecting the O/E to the TekConnect interface.

Values are the root mean square (RMS) distribution of vertical noise with either no optical input or
noiseless optical input. Noise is representative of a DPO70000SX system with the vertical scale set

Performance verification
Performance verification
If you are not familiar with operating this instrument, read the instrument user
manual or explore the online help.
These performance verification procedures add direct checking of the warranted
specifications that are marked with the symbol. These procedures require
specific test equipment.
Functional tests
The purpose of these procedures is to confirm that the instrument functions
properly.
NOTE. These procedures verify functions; that is, they verify that the instrument
features operate. They do not verify that they operate within limits.
Therefore, when the instructions in the functional tests that follow call for you to
verify that a signal appears on-screen "that is about five divisions in amplitude"
or "has a period of about six horizontal divisions," etc., do NOT interpret the
quantities given as limits. Operation within limits is checked in Performance
Tests. (See Performance tests on page 20.)
NOTE. DO NOT make changes to the front-panel settings that are not called out
in the procedures. Each verification procedure will require you to set the
instrument to certain default settings before verifying functions. If you make
changes to these settings, other than those called out in the procedure, you may
obtain invalid results. In this case, just redo the procedure from step 1.
When you are instructed to press a front-panel or screen button, the button may
already be selected (its label will be highlighted). If this is the case, it is not
necessary to press the button.

Performance verification
First turn on functional checks
1. When a DPO7OE Series probe is plugged into a 70k series oscilloscope for
the first time, measured S-parameters for the probe are copied from the probe
internal memory to build custom correction filters. The message pictured
below appears on the screen while this process takes place. Total operation
time may take over a minute.
2. Once complete, the message will disappear.
Verify that the message appears the first time the probe is attached to the
instrument.

3. The probe model number and serial number can be verified in the Probe
Properties screen, accessible from the Probe Setup menu.
4. Attach the probe to the instrument.
5. Select Vertical > Probe Cal to open the Probe Setup panel. Select the tab for
the channel that the probe is attached to.
6. Press the Properties button.
The Probe Properties window is displayed.
7. Verify the probe model number and serial number.
