Thetis + Anan 10E + PureSignal Issue
Posted: Mon Aug 12, 2024 9:09 am
Despite quite some time spent I have failed to get PureSignal to work. I am hopeful this is just finger trouble but I have been unable to identify what I am doing wrong.
I am using an Anan 10E together with an RF2K external amplifier.
When I use PowerSDR with this configuration PureSignal engages and performs well both barefoot and with the external RF2K. In both cases an external SA tapped from my dummy load indicates IM3 at close to -60dBc. All good.
The PS tap output from the RF2K is at around 0dBm which seems to suit PowerSDR well. I read somewhere that feedback should be around -17dBm so I introduced a 20dB attenuator. With this in place PowerSDR PureSignal fails with feedback flagged red.
With Thetis and feedback at 0dBm or -20dBm I cannot get PS to respond. With PS-A enabled the flag at the bottom right of the Pan display is green whether TX or RX. With a two tone signal neither the Pan display nor Amp View reveal any PS response. The flag remains green with the words Feedback PureSignal2. If I disable PS-A and try a single cal the green flag turns grey but still no observable PS activity.
Help sought and advice appreciated.
Thanks.
