Anritsu has announced a pair of cable and antenna analysers with options up to 6GHz, one with a spectrum analyser. “RF cable runs continue to be an integral part of radio communication base stations, from long runs on broadcast transmitter towers to short jumper cables on cellular base stations,” said the company. With the deployment of distributed antennas systems, the ...

Rohde & Schwarz has introduced a rack-mount 2GHz display-less oscilloscope with eight channels that fits into a 2U (89mm) slot. It has eight 2.5Gsample/s channels that can be interleaved to provide four 5Gsample/s channels, and is part of the new MXO 5C series of scopes which have been cut down from the recently-introduced display-inclusive MXO 5 series. As well as ...

Intepro Systems is stocking a 50kW regenerative ac-dc electronic load and grid simulator from Cinergia. Called ‘GE&EL+ vAC/DC SiC’, Intepro describes it as: “The whole Cinergia catalogue in a single unit. [It] is both an ac and dc grid emulator, and can also works as a load [and] is ideal for testing solar panels, wind turbines, hardware-in-the-loop power, smart grids, ...

Segger has made a four channel version of is Flasher Hub production IC programmer to save space on the production floor. ‘Flasher Hub-4’ is a compact version of Flasher Hub-12, measuring 125 x 78 x 25mm. “It is just a little bigger than a standard deck of cards, making it the most compact and efficient control unit on the market ...

Fluke is aiming at mid-sized solar power installations with PVA-1500HE2, an analyser and I-V curve tracer rated at 1.5kVdc and 30A. “Similar products can often struggle to obtain accurate readings due to high capacitance levels and are incapable of recording data continuously without overheating,” claimed the company. “Having to disconnect an I-V curve tracer until it cools down is disruptive. ...

We caught up with Siglent in Nuremberg at Embedded World 2024 as part of our promotional coverage for the event. Thomas Rottach – Sales & Marketing Director of Siglent – discusses presenting the company’s new flagship oscilloscope, the SDS7000A, at the show. He covers, for example, its 4GHz frequency range and vertical resolution of 12 bits, enabling the company to ...

Historically, component temperature has been correlated with reliability, with early studies relating field failure rates to steady-state component temperature. More recently, physics-based reliability prediction has related failure rates of electronic assemblies to the magnitude of temperature change over an operational cycle (power-on, power-off, power-on…) and rate of temperature change, both of which are influenced by steady-state operating temperature. Electronics failures ...

Quadsat, the Danish drone-based antenna testing company, has launched its product range with an extended breadth of frequency ranges and the addition of uplink capabilities. The Quadsat range for RF measurement comprises: QS 1-18 DL (downlink tests, covering S-KU band), QS 6-24 DL (downlink tests, X – KA low band), QS 17-31 DL (downlink, KA band), QS 6-24 DL/UL (downlink ...

Toshiba is eyeing semiconductor test applications with a tiny photo-relay that operates at 1.6Vin “making it suitable for use with 1.8V FPGAs”, according to the company. “A resistor is built in on the primary side, enabling voltage-controlled operation.” Called TLP3412SRLA, it draws 6.6mA at the nominal operating voltage of 1.8V. Inside is a single Form-A (normally-open) ac or dc contact that ...

Transient gate overvoltage ringing during turn-on is a common phenomenon in GaN-based power converters, but a lifetime equation can account for all bias conditions with respective fractional lifetime, say Shengke Zhang, Han Gao and Siddhesh Gajare. Gate overvoltage spikes during device turn-on transients are commonly observed in GaN HEMTs (high electron mobility transistors) under high frequency, fast-switching conversion applications. The ...
