Offered in DC and AC/DC versions, the MeasureReady 155 from Lake Shore Cryotronics serves as a low-noise source of current or voltage in the lab. The 155 performs precision DC I-V and C-V curve ...

The low-noise MeasureReady™ 155 precision current and voltage source combines excellent performance capabilities with an unprecedented simplicity that provides both materials scientists and engineers ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

In high voltage applications involving tens of thousands of volts, too often people think about the high voltage needed but don’t consider the current. This is especially so when part of the circuit ...

Proper calibration of this test equipment is crucial to meeting the strict performance requirements of many high-voltage systems. Calibration results often need to comply with national or ...

Makers of programmable power supplies and loads have been busy on a variety of fronts. They have focused on minimizing ripple and distortion, cutting weight and cost, improving usability and interface ...

As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...

This article is the final installment in a seven-part series on the effects of power quality disturbances on a five-stage electronic LED driver. In the first three parts of this series, we touched ...
