N4011A Introduction
The N4011A MIMO/Multi-port Adapter is a 1/4 rack-width
unit, used in conjunction with a N4010A test set to
provide additional features to support production testing
of multi-port MIMO-capable devices and modules. It
provides a switch matrix to connect the multi-ports of the
device-under-test (DUT) to the single RF In/Out port of
the N4010A. In addition, the N4011A provides interfaces
to allow the DUT to be connected to a reference (golden)
radio.
The N4011A will operate functionally at power-up, within
the stated environmental operating range, and perform to
specification after power-on assuming the unit is in the
temperature range 20 to 30 °C.
Note: The power cable from the N4010A test set must be
connected to the N4011A adapter with the power off.
Unless otherwise stated all specifications are valid over
the temperature range 20 to 30 °C. Supplemental charac-
teristics are intended to provide additional information,
useful in applying the adapter by giving typical (expected),
but not warranted, performance parameters. These charac-
teristics are shown in italics or labeled as nominal.

General conditions The conformity assessment
requirements have been met
using the technical construction
file route for compliance with the
requirements of the EMC Directive
89/336/EEC
1. Actual S-parameter data, over the frequency range 2 to 6 GHz, is stored
within the N4011A.
2. Automatic path loss compensation performed by the N4010A is applied
between RF IN/OUT and DUT ports.
