Zigbee Toolkit : Procedure for Receiver Sensitivity Testing (PER)

Zigbee Toolkit supports PER using the niWPAN 2450 Receiver Testing Example present at this location

Procedure for Receiver Sensitivity Testing (PER) is briefly mentioned below..

1. Program the Zigbee DUT with the wanted RF configuration (RF frequency,modulation format, deviation, data rate etc.), and put the device in RX.

2. Configure the  niWPAN 2450 Receiver Testing Example (RFSG) with the corresponding RF settings.

3. Use a DATA Frame (containing preamble, sync word, and payload) for transmission.

4. Read the RXFIFO content and compare it to the known bit sequence bit for bit. Since each bit is checked a CRC check is redundant .

5. Repeat steps 3 and 4 for a sufficient number of packets (At least 100 packets is needed to give a reliable PER figure).

6. Adjust RF level from the generator and start from step 3 again. This is repeated until the wanted PER level is found.

7. Around the sensitivity limit a larger amount of packets is sent to accurately find the limit,

    meaning increase the packet count from 100 to 1000 around the Sensitivity Limit

8. Log the final result in an output file.

As mentioned in the IEEE 802.15.4-2003 Standard, the following Receiver Tests are supported.

-Receiver Sensitivity

-Maximum Input Power

-Adjacent Channel Jamming Resistance

-Alternate Channel Jamming Resistance
