Have not ever look at the amp view till the other day and i am sure by looking at others this is not right ?

Sampler is Xtronic

10 dB Attenuator

1) What do you think isn't right about that graph?

2) Where did you get that SetPk value?

The Dotted line dose not seem right others i have seen are solid lines ..

Setpak value i never set .

I've noticed the dotted lines when I use TwoTone to trigger PS correction. When I'm using voice to trigger PS the curves are solid.

There's nothing wrong with those results if you are using two-tone. As previously mentioned the dotted line is an artifact of the two-tone waveform. What power level was being used when you grabbed those screenshots?

However, you may want to revisit your SetPk value. Make note of the current value, then press the default button and see if it changes. If it does change, take a fresh look at the performance of PureSignal with the default setting for the 200D. If you are not happy with that then just put old number back in.

Thank you guys i am using two tone @ 45 watts and the setpak values are my default.....

The curve shapes are very reasonable and the dotted blue and yellow lines are fine. To calibrate, PureSignal collects samples as the two-tone (or voice) goes up and down through the range of possible amplifier outputs. Since these are "samples", they are distinct points, not a curve. A two-tone is repetitive and so the samples may fall at the same places multiple times. Voice is much more random and the samples tend to be more dispersed, eventually filling in what appears to be a curve but is actually just a collection of points.

In contrast, the "correction" lines (red and green) should be solid. These are plots of the correction curves calculated by PureSignal in response to the input samples (blue and yellow) it received.

Hi Brent,

As another ANAN 200D owner I am with Mark and very curious about your SetPk value. My 200D is running protocol 2 and displays a very different default value for SetPk. I too am using an Xtronic coupler with 10dB of attenuation inserted in the return line. Just curious if pure signal is stable for you?

Thetis v2.10.3.6 Dev 2
F/W version 1.9.20B (Protocol 2)

The correct value of 'SetPk' is ONLY dependent upon the firmware in use. It does not depend upon the coupler, or any other hardware or parameter. As of this date, there are three different values of 'SetPk':
ANAN-G2 (protocol_2): 0.6121
All other protocol_2: 0.2899
Protocol_1: 0.4072

Thetis should set this value automatically, depending upon the radio selection and firmware in use. However, I understand there has been a recent bug and that might not be happening in all cases.

@lauchlin -- are you running Protocol 1 firmware?

I am running protocol 1

So many of us have gone to P2 that we've obviously forgotten that .4072 is the correct value for SetPk under P1
