The sweep frequency is not correct

I think you did everything right based on the datasheet but when I tried to send 1kHz to the Vout it is actually not 1kHz. I am not sure whether it is a problem with my setup or something is wrong in the datasheet. I changed the start frequency code equation and now it works.

can you tell us what exactly that you change in the start frequency equation for it to works? i've been looking for days to what causing the measurement not correct and still not found it...
thank you in advance

Hello, I know it's been a long time, but we all seem to have the same problem. Could you share your solution? Thank you
