AWR6843AOP: how to set frequency to specified target for EIRP test?

Part Number: AWR6843AOP

hi,

my customer wants to set output frequency like 60, 62, 64 GHz.

They want to test EIRP.

Can I know how to do that?

BR,

frank

    Hello,

    You would need to set the startt frequency to the intended frequency and enable ContStream transmission. Chirp mode woiuld not give the right values for EIRP characterization. You can then use a power meter with a known gain Antenna at a measured distance (preferably in an Anechoic Chamber). Attenuation in the signal from the measured distance can be calculated.

    It is important to make sure that the power meter and Antenna will work at the desired frequency. If the power meter is designed for a lower frequency, use a down coverter to down convert the frequency.

    Hope this helps.

    Are you familiar with mmWave Studio?

    E. Shareef,

    No, I don't have DCA1000 and never use mmWave Studio before.

    correct me if my understanding is wrong.

    DCA1000 is to get RF raw data. Customer should have expertise of Radar RF to analyze the raw data.

    So, most customers don't have capability and don't need DCA1000.

    For EIRP measurement, customer must use DCA1000 + mmWave studio?

    No, DCA1000 is not necessary for EIRP.

    The customer must be aware of APIs they are using to send commands to the device. They can use these APIs to radiate into a power meter. Alternatively, they can also use Studio, which is TIs version of a GUI that can be used to send APIs to the device. 

    Hope this helps,
