The difference between impedance analyzers and network analyzers

August 5, 2022 By David Herres Leave a Comment

At first glance, impedance analyzers and network analyzers seem to do the same thing: Describe the impedance of whatever is connected to their inputs. This statement is true as far as it goes, but as you might expect, there are significant differences between the two types of instruments. Here’s a review of the basics. There […]

Shedding light on frequency and wavelength

July 20, 2022 By David Herres Leave a Comment

Today, an advanced multimeter such as the Fluke 287 in volts mode accurately displays frequency. High frequencies are displayed in a bench-type frequency counter, which can read above 100 GHz. At still higher frequencies, measurements are made indirectly via heterodyning to down-convert the signal. Using a diode or similar device as a mixer, a frequency […]

ESW EMI test receiver bandwidth goes to 1 GHz

July 12, 2022 By Lee Teschler Leave a Comment

Rohde schwarz

The R&S ESW EMI test receiver will offer the possibility to increase its FFT (Fast Fourier Transform) bandwidth to 350 MHz with the new R&S ESW-B350 option, and to a market-leading 970 MHz with the new R&S ESW-B1000 option. This makes the R&S ESW not only an instrument of highest performance in RF, functionality, versatility […]

Tester evaluates internal battery electrochemical and electrical properties

July 7, 2022 By Lee Teschler Leave a Comment

bk precision

The BA8100 is designed to test batteries using a complex AC measurement technique known as electrochemical impedance spectroscopy (EIS). Through this technique, the BA8100 derives the internal impedance of a battery across a wide frequency sweep. The acquired data is used to display a graphical representation of electrochemical processes occurring within the battery. The BA8100 […]

Measuring ESR and ESL of dc-link capacitors

June 30, 2022 By Tim Ashworth, Meng Li Leave a Comment

Impedance analyzers work better than LCR meters when it comes to sizing up the super-low impedance and inductance of modern power converter capacitors. Tim Ashworth, Meng Li, Zurich Instruments DC-link capacitors are often found in power conversion applications such as inverters, motor drives, medical power supply equipment, and so forth. Consequently, dc-link capacitors often need […]

Current Digital Issue

A frequency you can count on There are few constants in life, but what few there are might include death, taxes, and a U.S. grid frequency that doesn’t vary by more than ±0.5 Hz. However, the certainty of the grid frequency is coming into question, thanks to the rising percentage of renewable energy sources that…
