Decibel Measurement dBu

Post by GMaier »

Hello, I am using a PicoScope 3204B and PicoScope Software 6.14.54. I want to measure a sine wave at channel A with unit dBu. Therfore I have to use the formula L = 20 * log (A / 0,775 V) with L [dBu], A = channel A. In Scope Mode I want to make a measurement with this formula. But there is no way to define a formula by user. How can I measure dBu from sine wave at channel A with PicoScope? Thank You all ... Gerhard
