how to use 2015 to get signal to noise value?

Post by jerryhey » March 22nd, 2011, 1:12 pm

Hello:

I'm using the 2015 model to test signal to noise ratio value, however, there's only one example in the manual or quick start guide to show how to get THD value(quick guide, from page11 to page12). Since the value unit for signal to noise ratio is also dB, can I get it from 2015 in some way?

Furthermore, is there something special I need to pay attention with regard to cable connections on 2015?
Thanks for your reply

I have not found any more specific examples to measure THD.
But to set the unit to THD result in dB use the following command
:UNIT:DISTORTION DB
This can be in dB or percent
:UNIT:DISTORTION PERCENT

hello

In the quick guide manual 2015_903_01A, page 11, there's an exmple to show the cable connections and how to get THD value from front panel operations.

My problem is: whether I could use 2015 to get S/N(signal to noise) value?

I've tried for many times but in vain, could you please kindly help me?

Thanks
