I want to test the sensitivity of the chip in signaling mode by the instrument of CMW500.It is found that the bit error rate is 5.5% at the receiving level at -40dBm, and less than 2% at the receiving level at -80dBm. Please help to check what the problem is.
Hi @chen ,
Thanks for reaching out to us, could you kindly provide information as follows so our engineers can understand your situation better?
- data rate
- Test setup & procedure
1.click signal gen–>Signaling(WLAN)
2.setting–>standard:IEEE 802.11b;BW:20MHz; channel:1;
3.After connecting the instrument, click on WLAN1 PER for sensitivity test
Below are pictures of the test steps and results
It seems the device and Instrument are not paired successfully
yet, Rx Sensitivity test can be done with RTK in-house MP tool.
may we know your company location? do you know if any NDA between your company and RTK?
if so, we could advise the local team/ AE to support you directly
We should not have NDK with RTL。 The MP tool is tested in non-signaling mode,we can not measure real usage
@xidameng hi，is there any other way to test the correct sensitivity?
Hi @chen , without more detailes, its hard to troubleshoot for you
Hi,to test antenna performance，it need to be run OTA test in a dark room.Have you done a case like this?
may we know if it is standard module of RTL8720DN ?
can you please help to provide pics of RTL8720DN?
meanwhile, can you provide test log as well?
can you pls share with us about these info?
