The LDC1000 is a relatively recent device introduced by Texas Instruments about a year or two ago – it is designed to measure inductance to a high resolution (24-bit!) in an extremely convenient single-integrated-circuit solution.   Metal objects close to a coil can affect the coil’s inductance sufficiently for it to be measured with the LDC1000.   Here is TI’s LDC1000 evaluation board:   The board is a convenient USB stick with snap-able sections to separ ...
Intro  One of main Keithley Instruments expertise are low-level signal measurements. Since very beginning company had instruments as null-detectors, microvolt voltmeters, electrometers. As of today, current nanovoltmeter is Model 2182A, which features two channels with range down to 100mV with 7½ resolution. Predecessor of this instrument was sensitive voltmeter Model 182, which we will look on today.   It’s possible to get one of these from secondary market for about $1K ...

Electronic Load Part 2

Posted by waelect Aug 31, 2015
Hi Everyone,   I am really quite busy with a lot of setting up of the lab area. I hope to place a video of my changes in the lab work layout and my equipment shelf builds.   I have taken a small time out to place a video on my attempt at SPICE simulations on the electronic load all-be-it very simplified. I have not yet learn't how to create new component SPICE models on LT SPICE and MultiSIM blue (oops) but I at least have a simulation running. In the video I noticed the source serie ...
