Safety Summary
To avoid potential hazards, use this product only
as specified.
To avoid fire or personal injury
Connect and disconnect properly. Connect the
adapter to the host instrument before connecting
the SMA device to the device-under-test. Discon-
nect the device input and ground from the device-
under-test before disconnecting the SMA device
from the adapter and host instrument.
Ground the product. This product is indirectly
grounded through the grounding conductor of the
host instrument power cord. To avoid electric
shock, the grounding conductor must be con-
nected to earth ground. Before making connec-
tions to the input or output terminals of the prod-
uct, ensure that the product is properly grounded.
Observe all terminal ratings. To avoid fire or shock
hazard, observe all ratings and markings on the
host instrument. Consult the host instrument
documentation for further ratings information
before making connections to the host instrument.
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.
Do not operate with suspected failures. If you
suspect there is damage to this product, have it
inspected by qualified service personnel.
Do not operate in wet/damp conditions.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry.

Product Description
The TekConnectT-SMA adapter allows you to
connect SMA-terminated devices to Tektronix
instruments with the TekConnect interface. The
adapter preserves maximum signal integrity and
eliminates the need for additional external
adapters, which can degrade voltage standing
wave ratio (VSWR).

Using the Adapter
The adapter connects directly to the Tekconnect
interface on the host instrument.
Installing the Adapter
1. Insert the adapter into the TekConnect
interface on the host instrument until the
adapter locks in place.
2. Connect the SMA cable to the adapter.
3. Connect the other end of the SMA cable to the
device under test.
NOTE. For high-frequency input signals
(above 10 GHz), make sure that the input
cables do not exert upward pressure on the
adapter. Upward pressure can affect the
connection to the host instrument, which
could degrade signal quality.
Removing the Adapter
1. Disconnect the SMA cable from the device
under test.
2. Disconnect the SMA cable from the adapter.
3. Press the button on top of the adapter (see
Figure 2) to release the lock and remove the
adapter from the host instrument.
NOTE. It may be necessary to remove the
adapter before installing the host instrument
cover.
