Expected PER while using DTM and 2 nRF-dev boards

[user123]

Hi

I'm preparing for some tests and I'm wondering where I can find information about what the expected percentage error rate should be?

Right now with 2 nrf boards connected I get around 0-1% PER while testing every channel.

Well the test is done because of new RED requirements. So all new units needs to be approved by a blocking test specified in ETSI 300 328.

During the test no antennas are connected so there will be a coaxcable connecting the two units

Are you talking about "Receiver Blocking" part (section 4.3.1.12) of ETSI TS 300 328 (v1.9.1 from 2015-02)? It seems not applicable to BLE devices (or at least that's how I interpret " Applicability" section "In addition, this requirement does not apply for equipment with a maximum declared RF Output power level of less than 10 dBm e.i.r.p. or for equipment when operating in a mode where the RF Output power is less than 10 dBm e.i.r.p."). Am I missing something?

Hmm thats interesting. I will have to take a further look into that

Im reading 2016-11 and to me it looks a bit different but I might be wrong

Oh you are right, there are heavy changes in version 2.2.1 (2016-11)! Now it seems to me that BLE device might belong to "Category 3 equipment" (???) but I don't understand Tables 6/7/8 to be honest so hard to help how they imagine this test according to this new proposal. It looks to me like still under review, do you expect this being demanded for conformance in EU any time soon?
