Hope this find you as well!
We entered into Moku:Go Lockin Amp mode through Python sample code provided on the web site.
Then, connect input 1 with modulated signal and input 2 with reference signal.
And we find that the demodulated signal presented in different bit number in External mode and External PLL mode, respectively.
As shown in following 2 figures,
figure 1 shows the demodulated signal in External mode;
figure 2 shows the demodulated signal in External PLL mode.
P.S. PLL module were set as Frequency: Auto; PLL Frequency: 10kHz (same as reference signal); PLL BW: 10Hz
We are wondering whether we could make the presenting bit number of External PLL mode same as External mode?
Thank you for your assistance in advanced!
