The HDO Series of High Definition Oscilloscopes features true 12-bit resolution and are available in 70 MHz – 800 MHz bandwidths and two or four channels. The HDO Series is powered by the new UltraVision III platform featuring a custom ASIC chipset, which also provides for dramatically lower front-end noise. The higher resolution and lower […]

Antenna test system enables temperature-controlled measurements, polarization access
The R&S ATS1500C antenna test system from Rohde & Schwarz offers a new temperature test option and a new feed antenna. These additional features enable temperature-controlled measurements in a wide temperature range as well as parallel access to both polarizations, increasing test efficiency and flexibility. The movable R&S ATS1500C is a compact antenna test range […]
Test setup verifies mobile industry processor interface A-PHY layer compliance
A new automotive serializer/deserializer (SerDes) receiver (Rx) compliance test solution verifies mobile industry processor interface (MIPI) A-PHY devices based on the Compliance Test Specification (CTS) requirements. This solution was developed in collaboration with BitifEye Digital Test Solutions GMBH and Wilder Technologies, with the support of Valens Semiconductor Ltd.. Silicon vendors are planning to implement MIPI […]
Things to know about multimeters
For years, ohmmeters have been integrated into the electrician’s multimeter. This is convenient, because ohms and volt are the most-performed measurements. Also, only a single instrument must be purchased and maintained. Multimeters are further subdivided into ac, bench-type multimeters and hand-held, battery-powered multimeters. The hand-held instruments are more convenient. Most often just grab your handheld […]
What’s all this Helmholtz coil stuff?
The Helmholtz coil was not devised to create a magnetic field, but to cancel it. The Helmholtz coil actually consists of two identical circular air-core coils, large enough to contain the work under study. The coils are situated along a common axis that extends through the experimental area. The distance between the coils is equal […]
Sorting out balanced cables and differential signaling
Lines carrying symmetric signals, i.e. those with opposite polarities but with equal amplitudes on each line are commonly called balanced. But the correct term is differential signaling. While balanced lines and differential signaling may be used together, they are actually quite different. The key point that distinguished balanced lines from single-ended lines is that both […]
Ultra-wideband, omnidirectional antennas optimized for radial isotropic measurements from 150 MHz to 18 GHz
Aaronia OmniLOG PRO Omnidirectional Antennas are compact, ultra-wideband omnidirectional antennas suited for radial isotropic use from 150 MHz up to 18 GHz, encompassing most RF sources such as LTE, GSM, UMTS, WLAN, etc. These cost-effective antennas are specified for 1 W cw receive and 100 W cw high-power transmit, making them candidates for broad-range spectrum […]
BNC interface lets piezoelectric sensors hook up to data acquisition gear
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 […]
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 […]
