RSA306B EMCVu RBW issue

Post by yo3fff » May 9th, 2020, 7:19 am

Hello,

I need to perform an EMC measurement using RBW 1MHz but I can't set the RSA306B with RBW greater than 500kHz.
The frequency range is 80 - 110MHz.
I can see that the RSA 306B is capable of RBW 20Hz to 8MHz.
What is wrong?

Thank you.

BR,

Cristian

Can you provide a .setup file? I don't see this problem (provided the Range limits are wide enough).

I was able to change it to 1MHz (see attached). There may be something else in your setup that is limiting this. Can you attach a EMCVu project setup file .emcsetup? (Setup Wizard > Save Project Setup)

I found out from engineering that the CISPR 16.1 standard has a limit on Band C (30MHz to 1GHz) for the 6dB RBW range of 100k to 500k. Therefore, this limit was put into EMCVu.
