N4011A Agilent Adapter

Additional Features:

• MIMO-Multiport Adapter
• Comprehensive 802.11n test coverage when used with N4010A Option 108 – provides confidence that your product is performing to specification
• Independent channel measurement of 802.11n MIMO transmitters - ensures MIMO device under test (DUT) performance by capturing all failure mechanisms
• Fast measurement speed with accuracy and repeatability – reducing test times and increasing throughput
• Golden (reference) radio connection to the DUT – enables calibrated multi-channel receiver tests and uplink/downlink throughput testing
• Multi-up testing of 802.11a/b/g WLAN formats – increasing throughput by using the N4011A DUT test ports plus fixturing
• Automatic path loss compensation, performed by the N4010A, is applied between the RF In/Out and DUT ports - optimizing measurement confidence

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.

The N4010A Option 108 and N4011A combination provides full 802.11n test coverage, plus the fast switching hardware and software to allow sequential capture and analysis of WLAN bursts on multiple channels. This innovative technique gives a greater insight into failure mechanisms when compared to composite signal testing, so that even problems such as poor channel isolation can be quickly identified and diagnosed.
