We have an GWInstek GDS-1102A oscilloscope; is there any set of differential probes that could apply to this oscilloscope? and can you supply it?

Hi Javier,

What is the peak voltage and maximum frequency of the signal that you are looking to measure? Is it mains voltage?

Please find below a link that shows the Active Differential Oscilloscope Probes that we sell:

We are repairing servomotors, so the peak voltage shouldn't go beyond the 500 VAC; about the frecuency I am not sure, but we will be reading the feedback signals mainly the U, V and W feedback signal comming from a motor with up to 5000 RPM with at most 4 cycles per revolution.
Hope this information will be enough for you to help us.
Best Regards,
Javier

Hi,

Thanks for your reply.

If your voltage is not going above 700V, and presumably the frequency is below 25MHz, then the TA041 probe should be suitable:

You can purchase this direct from us or through one of our distributors:
