Siglent SDL1020X-E high-pitch noise

(1/2) > >>

alo:
Has anyone else noticed a high-pitch noise coming from their Siglent E-load SDL1020X-E?

Only the youngest 3 (age 23-25) out of a dozen of us can hear it. The high-pitch noise seems to randomly start or stop whenever the left arrow or right arrow buttons are pressed. This only happens when we're providing current to the E-load.

We really like this product but the high-pitch noise issue has deterred us from buying one after we gave it a trial. Did we just happen to trial a faulty one or is this an inherent problem with this product?

Um the SPD is a power supply not a load… you weren’t connecting it to another power supply were you?

Welcome to the forum.

Can we ask whom supplied it ?
If you are near us in Auckland we would like to see and know more about this issue.

Oh sorry, wrong product number. Should be SDL1020X-E. Corrected now.
