A Discussion and Demo of my HP 3410A Selective Microvoltmeter and measuring low level AC voltages.

** Programming Electronics Academy ** https://www.programmingelectronics.co... #ElectronicsCreators ----------------------------- Click "Show more" ------------------------------------------ In this video: I chat about the purchase and damage / repair to an HP 3410A Selective Microvoltmeter. I discuss the challenges of measuring really low AC signals / voltages. This is a prelude to a video about measuring the SNR (signal to noise ratio) of audio equipment. In that video I will demonstrate the capability of the following meters: * Handheld multimeters * The Rigol 3068 with a claimed noise floor of 5 uV. * The HP 3458A * The HP 3400A * The B&K (Bruel & Kjaer) Type 2609 * The HP 3410A * A "secret" German device from the 1980's that will measure down to around -130dBm / -144dBV / ~50-60 nano-volts. #ElectronicsCreators ------------------------------------------------------------------------------------------------------ Support me through Patreon or by using my Amazon Store: Patreon:   / mjlorton   Amazon Store: http://astore.amazon.com/m0711-20 Or anything on Amazon: http://www.amazon.com/?_encoding=UTF8... ----------------------------- Click "Show more" ------------------------------------------ ** Programming Electronics Academy ** Sign-Up below to join over 20,000 awesome people to learn from our Arduino Crash Course - it's 12 optimized video lessons to get you up and running quick with Arduino. https://www.programmingelectronics.co... ------------------------------------------------------------------------------------------------------ My website and forum:- http://www.mjlorton.com Donations and contributions:- http://www.mjlorton.com My techie channel MJLorton - Solar Power and Electronic Measurement Equipment -    / mjlorton   My Techie Amazon Store: http://astore.amazon.com/m0711-20 My other channel VBlogMag - For almost any topic under the sun! -    / vblogmag   My VBlogMag Amazon Store: http://astore.amazon.com/vblogmag-20 ------------------------------------------------------------------------------------------------------ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Bitcoin (BTC) Donations: 1K7PeF55e7ssE7W3WVCoa7c4j2PHzy6ASv $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ ********************************************************************************** Music clip from Youtube Music Library - Phase Three by Huma-Huma **********************************************************************************
