Anritsu has cut down its ME7873NR 5G New Radio RF conformance test system to create a bench-top ‘Lite’ model (right) supporting 5G sub-6GHz (FR1) TRx test cases. “ME7873NR Lite is an all-in-one tester,” said the company. “In comparison to the predecessor rack models, the lite model has stronger test performance at a reasonable price as a result of cutting the ...

Dutch test gear maker TiePie Engineering has introduced a module that can wirelessly time-synchronise and remotely access multiple instances of its PC oscilloscopes. ‘Wireless multi instrument synchronization module’ WCMI-8 can synchronise series 5 and 6 of both the company’s WiFiScope and Handyscope instruments, at up to 400m range “combining them to a single instrument”, it said. The 868MHz module is ...

Yokogowa has added HCDR (high close-in dynamic range) mode and SMSR (side mode suppression ratio) mode to its AQ6370 optical spectrum analyser. Found in AQ6370E, HCDR mode allows measurement of a single longitudinal mode laser with a high close-in dynamic range – CDR is a metric important when developing lasers and optical devices. SMSR mode is intended to halve SMSR ...

Toshiba has introduced a photo-relay in a 1.45 x 2mm package that switches on in 250μs – 50% quicker than its existing TLP3475S. The new part, TLP3476S, is in a 1.5mm high (max) S-VSON4T package, has a maximum on-resistance of 1.5Ω, can carry 400mA (ac or dc) and isolates up to 500Vrms. 3mA is the maximum LED drive needed to ...

Pickering Interfaces has teamed up with Menlo Microsystems to introduce MEMS switching to a range of PXI and PXIe RF multiplexer modules. “MEMS-based RF multiplexers deliver increased operational life – up to 300x, faster operating speed – up to 60x, higher bandwidth and increased RF power handling versus traditional electromechanical relay alternatives,” according to Pickering. “Insertion loss remains comparable with ...

Microchip has announced a cesium atomic clock that can keep time for months in the event of GNSS denials, according to to the company. Called 5071B, it comes in a 3U (three-unit high) 19inch rack-mount enclosure. Compared with the existing 5071A, the next-generation 5071B “has upgraded electronic components to address possible obsolescence or non-RoHS [Restriction of Hazardous Substances Directive] circuitry” ...

Powered and operated through a USB Type-C cable, Analog Discovery 3 is a 9MHz (or 30MHz) 125Msample/s 14bit oscilloscope, a logic analyser, an arbitrary waveform generator and more from Digilent. “Analog Discovery 2, AD3’s predecessor, has been used as a learning tool in hundreds of universities, and as a flexible benchtop tool by thousands of professional engineering companies and organisations ...

Pickering Interfaces has announced a range of PXI and PXIe microwave relay modules capable of switching signals up to 110GHz in 50Ω. They will be reveals for the first time at IMS in San Diego next week. 40-781A-92x (PXI) and 42-781A-92x (PXIe) consist of either a single or dual microwave changeover switch. Connections are via front panel SMA 1.0 connectors, ...

Tektronix has created a automated double-pulse test set-up for GaN and SiC power supply designs, that also works with silicon mosfets and IGBTs. Called ‘WBG-DPT Solution’, it is a combination of test gear from its existing equipment portfolio, and software for that test gear, which makes measurements to JEDEC and IEC standards where applicable. “With the ability to run on ...

Pico Technology has introduced a display-less 30GHz sampling oscilloscope for use with a PC. Sampling oscilloscopes do not capture a whole waveform in one shot. Instead they are simpler, and work with repetitive waveforms only, using a fast sampling gate at a relatively slow sampling rate to build up a waveform one sample at a time. As such, they are ...
