A new interface allows the use of IEPE sensors on all data acquisition devices with a 1-MΩ BNC interface. The TA487 IEPE Signal Conditioner is a simple adaptor that allows any PicoScope or oscilloscope to capture and measure signals from a large selection of piezo-electric IEPE sensors, such as the Pico Technology TA095 accelerometer. Integrated […]
Test and Measurement Tips
Analyzing jitter with an oscilloscope
Jitter–basically the deviation between true and measured periodicity–is harmful beyond a certain level. In measuring jitter, we are calculating RMS, peak-to-peak deviation or spectral density. Jitter at frequencies below 10 Hz is known as wander. High-frequency signals are more prone to jitter than low-frequency signals. The deviation in periodicity that constitutes jitter may be in […]
Power choke testers measure up To 4 kA/7.7 kJ
The ed-k DPG Power Choke Tester family is a unique series of innovative measurement instruments for inductive power components, using currents up to 4 kA and pulse energy up to 7.7 kJ. The DPG series uses a large-signal impulse measuring method to provide a complete inductance curve as a function of the current L(i), or […]

Scanning for defects with sound waves
High-speed, non-destructive ultrasonic scanning identifies minute defects in specialty metals and alloys using advanced, phased array scanning acoustic microscopy (SAM). Hari Polu President OKOS High purity metals and alloys such as aluminum, zinc, cobalt, copper, titanium, zirconium, molybdenum, magnesium, and stainless steel are central to many different industries, including electronics, aerospace, and medical devices, among […]
The difference between solar cells and LEDs
Perhaps thanks to YouTube, more people understand that light emitting diodes (LEDs) and solar cells may be thought of as mirror images of one another because the conversion of energy in each involves similar interactions of charge carriers. It’s easy to find YouTubers who have either created solar arrays from LEDs or rigged solar cells […]
Single-sweep VNA-spectrum analyzer spans 70 kHz to 220 GHz
The VectorStar vector network analyzer (VNA) family now inclues the world’s first single sweep VNA-spectrum analyzer solution that supports 70 kHz to 220 GHz. With the spectrum analyzer option installed, VectorStar can conduct single connection VNA and spectrum-based measurements to create a more efficient and accurate testing environment to verify active and passive devices during […]
The difference between impedance analyzers and network analyzers
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 instrument. Here’s a review of the basics. There […]
PCI Express 5.0 interposer works with protocol analyzers
A PCI Express 5.0 Mini Cool Edge IO (MCIO) interposer works in combination with Teledyne LeCroy’s Summit family of PCI Express 5.0 protocol analyzers. The new interposer enables engineers to test products that incorporate card edge connectors or cabled connector assemblies that utilize the MCIO mechanical connector with PCIe 5.0, NVM Express (NVMe) or Compute […]
Polarization isn’t just for sunglasses
In a vacuum or homogeneous medium, the oscillations of magnetic and electric fields are perpendicular to each other and perpendicular to the direction of energy propagation. James Clerk Maxwell concluded that the principle of symmetry should imply that a spatially varying electric field is always associated with a changing magnetic field, and vice versa. In […]
