Classic techniques like videofluoroscopy, stationary manometry, and ambulatory 24 h pH-metry are routinely used in the clinic to study patients with dysphagia, chest pain and reflux-related symptoms.

Keysight Technologies today introduced three low-frequency options for its E4982A LCR meter. With these new options, the E4982A is suited for RF inductor, coil, and EMI filter manufacturers that are ...

Most precision digital multimeters (DMMs) and many source measurement units (SMUs) offer both two-wire and four-wire resistance measurement capabilities. However, these two techniques are not equally ...

Today’s electronic equipment must be designed to, first, operate in the electromagnetic (EM) environment it is to be employed in, and second, ensure that the EM fields generated by the system do not ...

In the second part of this series on the highs and lows of resistance measurements, I illustrated the differences between two-wire and four-wire resistance measurements on an actual low ohmic sample ...

We’ll begin by covering some of the basic mathematical relationships that everyone learns in electrical trade (or engineering) school. Unfortunately, many people seem to forget these basics in the ...

The contentious “right to try” bill that President Trump signed into law to help terminally ill patients get access to treatments that might — I emphasize the “might” — cure them or prolong their ...

Insulation resistance testing is one of the most useful predictive maintenance tests available. This test gives insight into the integrity of insulation. The higher the resistance across the ...
