MSOX4054A DC Voltage measurement

Question asked by harioyyoth on Jul 28, 2020

Dear Team,

 

I am performing a DC voltage measurement using MSOX4054A.

When I am using passive probes I am getting Proper voltage.

 

We have an SMA connector on the board for voltage measurement.When I connected the SMA cable I am getting a voltage which is less than the required voltage.If I connect the passive probe on the SMA connector voltage is proper.

 

May I know what is happening when I am connecting the SMA cable.

 

Regards

Hari
