An old Electronics Designer’s Casebook described a circuit that provided capacitance measurements of 10 pF to 1 µF with 1% accuracy (Reference 1). A number of issues emerged with the circuit during ...
If you need to measure capacitance but don’t have the necessary meter, you may be able to build a circuit that can handle the task. For example, if you have a data-acquisition board or module that ...
If you are just starting out in electronics, you need tools. But it is hard to build all your tools. Even though we see a lot of soldering station builds, you really ought to have a soldering iron to ...
BEAVERTON, OR. Tektronix Inc. has announced the availability of two new source-measure unit (SMU) modules for the Keithley 4200A-SCS parameter analyzer that can perform low-current measurements even ...
An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...
Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...
