Re: Effective number of bits of 5244B

Hi Karunen, I've computed the ENOB according 2 methods (both give almost the same ENOB value) Method 1: With AC noise 1- I mesure AC Vrms noise with PicoScope6 (using Measure Menu, input loaded with 540ohms). On my scope, I get Noise_ACVrms=118.4µVrms with vertical scale=+/-50mV 2- According to vert...

Effective number of bits of 5244B

Hi, I've checked the effective number of bits of my PicoScope 5244B and compared it to the specifications with different resolutions. I get: 5244B_ENOB_Meas-vs-Spec.jpg Both are close enough, but I'm a little surprised by the 'low' ENOB compared to the physical number of bits. So I've made the same ...
