As noted, this is of course for the PREVIEW software that is currently available (0.13.10). We expect to perform the same tests on subsequent releases, including V1 when it is released, naturally.
The scope of the testing, as detailed in the report is:
1. NPR (Noise Power Ratio). Test setup: Wandel & Goltermann RS-50 and RS-25 noise generators (fitted with the following filters), MCL 75/50Ω transformer, DUT ANT1. DUT set to LSB for all test frequencies except 5340 kHz (USB). 2.4 kHz channel filter selected.
Table 1. NPR test filters.
Equiv. J3E channels
2. RMDR (reciprocal mixing dynamic range). Test setup: Marconi 2018A signal generator, 20 dB pad, DUT ANT1. HP 339A distortion meter at DUT phones jack as level meter.
3. DR3 (IMD3 dynamic range). Test setup: Marconi 2018A and 2019 signal generators, 20 dB pads, MCL ZSC-2-2 combiner, 0-50 dB step attenuator, DUT ANT1. HP 339A distortion meter at DUT phones jack as level meter.
4. ADC clip level. Test setup: Marconi 2018A signal generator, DUT. Clipping observed on spectrum scope and headphones.
We may share these initial results in due course, but we're interested whether Flex Radio feel they are representative and/or likely to change much in the near term.
I gather many of the folks at Flex Radio may be traveling to shows at this time and they're probably crazy busy in order to close out V1 features and performance, so we're not sure when we'll hear back from them.
