DVC 1000 Voltage Sensors

The DVC 1000 series of voltage sensors for insulated nominal voltage measurements in rail traction and industrial applications offers panel-mounted voltage measurement in a package measuring 29 x 51 x 89 mm (131.6 cm³). Designed to measure a nominal voltage of 1000 VRMS, the series uses an isolating amplifier, providing a safety insulation voltage of 4.2 kV. DVC 1000 voltage sensors are suitable for a broad range of small-to-medium voltage measurements in industrial markets such as DC power supply monitoring, EV chargers, and battery-storage applications.

Sensing and Balancing IC

Designed for batteries in hybrid and electric cars,The TLE9012AQU sensing and balancing IC is also suitable for other applications. It measures the voltage in up to 12 battery cells with an accuracy of ± 5.8 mV over the entire temperature and voltage range, as well as the operating life cycle. It also supports up to five external temperature sensors, provides an integrated cell balancing function, and uses an iso-UART interface for communication. The TLE9012AQU provides the necessary measurement data, and ensures a balanced state of charge through cell balancing. Infineon Technologies

Inductive Position Sensor

Renesas Electronics’ magnet-free IPS2200 inductive position sensor features high accuracy and speed, total stray field immunity, and efficient motor integration, in a thin and lightweight form factor. Well-suited for use as an absolute position sensor in industrial, medical, and robot applications, among others, the sensor allows customers to cost-effectively tailor sensor design for their applications and maximize performance. The IPS2200 is designed around the motor, allowing customers to match the number of sectors to pole pairs of the motor to maximize accuracy, accommodating both off-axis (through shaft and side shaft) and on-axis positioning.

Thermal Power Sensors

Rohde & Schwarz added the R&S NRP90T and R&S NRP90TN models to its portfolio of thermal power sensors. Presented as the first test and measurement instruments in the market to support the novel, robust 1.35 mm precision coaxial connector, they cover frequencies up to 90 GHz. Emerging applications include automotive radar from 76 to 81 GHz, and the WiGig extension IEEE 802.11ay operating up to 71 GHz. These and others highlight the need for a novel, robust coaxial cable connector suitable for industrial applications at frequencies up to 90 GHz. Rohde & Schwarz

GX3788 Multifunction Instrument

The GX3788 High-Performance FPGA Multi-Function Instrument combines A/D, D/A and digital I/O functionality. The GX3788 is a user-configurable 3U PXI hybrid-slot-compatible instrument, with flexible digital and analog test capabilities. Suitable for challenging functional test applications, the instrument’s A/D channels can be configured as 8 differential or 16 single-ended inputs, supporting sampling rates of up to 250 KS/s. Alternatively, two-channel operation can support a sampling rate of 1 MS/s. The D/A channels support a simultaneous sampling rate of 1 MS/s, while the digital I/O channels are TTL-compatible and can be programmed as inputs or outputs. Marvin Test Solutions

LPDDR5 Grypper Sockets

Ironwood Electronics released new Grypper test sockets for the latest LPDDR5 memory. Ironwood’s GR1032-0001 allows testing of the latest-generation LPDDR5 devices that have 315 Ball at 0.7 x 0.8mm pitch, at speeds up to 6400Mb/s. The LPDDR5 Grypper socket fits to the same location/PCB footprint as the device, allowing development and failure analysis. The socket has an electrical performance of - 1dB insertion loss, up to 40.0 GHz. The force required to insert a device is 45 grams per contact, and the socket is sold in three configurations.

Positive Slope Equalizers

Pasternack’s latest positive-slope equalizers compensate for gain variation and optimize performance in systems where excessive losses may occur at the low end of the frequency band. They offer a broadband performance that makes them suitable for a variety of applications involved in aerospace and defense, MILCOM and SATCOM, test and measurement, and wireless infrastructure. The selection of positive-slope equalizers consists of 18 models operating over octave frequency bands from 500 MHz to 40 GHz. These 50-Ohm designs have fixed equalizing values from 2 to 8 dB, at the minimum frequency, and produce an attenuated response that increases linearly across the frequency band. Pasternack

SOLT Calibration Kits

Fairview Microwave unveiled a series of short-open-load-through (SOLT) calibration kits for use in lab, test and measurement, and RF and Microwave production test applications. Fairview’s expansion of its VNA calibration kit line consists of 12 models including short circuit, open circuit, and load kits (SOL), as well as short circuit, open circuit, load, and thru kits (SOLT). Interface options include 2.4mm, 2.92mm, 3.5mm, 7/16 DIN, 7mm, N-Type and BNC. Every model of VNA calibration kits includes the required short circuit, open circuit, loads, and thru (model dependent) components required for VNA calibration. Fairview Microwave
