Time Tamer BLADERF_VCTCXO_TAMER_1_PPS

Post by reesebo » Wed May 04, 2016 8:38 am

Hello

I've turned on 1PPS time taming using the call:

bladerf_vctcxo_tamer_mode mode = bladerf_vctcxo_tamer_mode.BLADERF_VCTCXO_TAMER_1_PPS;
status = NativeBlade.bladerf_set_vctcxo_tamer_mode(_dev, mode);

I have 1PPS input to the mini expansion header at pin 3. If I output a tone, I see the tone move periodically in the range of center frequency +/- 1khz. The update is 1Hz. If I disable the tamer, the tone is stable.

Any thoughts?

Thanks,

Reese

Sorry about that I said pin 3, I meant pin 1

Can you probe TP40 along with your 1PPS signal and post the scope plot?
