Receive Testing with LabVIEW

Procedure:

Step 1.

Connect the instruments and test board as shown in Figure 14.

Step 2.

Set the EM in Packet RX mode through SmartRF Studio.

Step 3.

Using LabVIEW, send 1000 packets at a specified data rate and modulation format from the

RF generator, while controlling the generator power. (Start 10 dB over the stated sensitivity of

the device.)

Step 4.

Measure the actual number of packets received.

Step 5.

Calculate the PER. If the PER is less than 1%, repeat the test with a reduced signal power.

When the PER

≥ 1%, the previous signal power with a PER less than 1% indicates the

sensitivity.

NOTE:

See Ref. 3 for more detailed techniques to test TI CCxxxx devices for sensitivity.
