Test & Measurement

Audio Precision has introduced a test instrument with two analogue audio generator/analyser channels and a swappable digital channel to address multiple data standards. “A standout feature of the APx516B is its capability to bridge analog and digital audio testing,” according to the company. The “digital interface module slot is compatible with all current and future Audio Precision digital audio I/O ...

Spectrum Instrumentation has introduced a way to parallel its 12bit 10Gsample/s data acquisition cards up to eight channels, that can also produce 16 12bit channels at 5Gsample/s. Called Star-Hub, it works with the company’s recently introduced M5i.33xx series of PCIe digitisers. “The Star-Hub option is installed by mounting a single piggyback module onto any of the M5i series cards in ...

Rigol Technologies has added 12bit oscilloscopes to its line-up, with a compact design which is flexible to use for both on-site and desktop testing”, according to the company. DHO900 oscilloscopes (right) have four analogue channels 16 digital channels and are available in 125 or 250MHz bandwidths, with or without an arbitrary waveform generator and Bode plot capability. Shared between the ...

For coastal and mountainous terrain, Anritsu has added an up-link interference measurement to its some of its portable 5G and LTE TDD testers. At issue are stray signals carried long distances into cells where they interfere with the TDD up-link. The company explained: For 5G networks with a coastal or mountainous terrain, RF down-link transmissions readily become subject to atmospheric ...

For the US market, TiePie has created a 915MHz version of the module that allows multiple instances if its PC oscilloscopes to be used together at up to 400m range – a 868MHz version for Europe was introduced in July. Wireless Multi Instrument Synchronization Module WCMI-9 also allows instruments to be used where galvanic isolation is required. The scopes can ...

TDK is aiming at motor testing with the introduction of a power sinking option to 1.7 and 3.4kW models of its Genesys+ 1U-high rack-mount dc power supplies – it is only available for 0-20, 0-30, 0-40, 0-60 or 0-100V output versions. Mounted internally, the sink module (photo below) can absorb 100W continuously and 300W of peak, and fall time can ...

Rohde & Schwarz has introduced 5GHz instantaneous bandwidth front-ends for its automotive radar test set-up. “From the automotive radar perspective, a higher instantaneous bandwidth improves the distance resolution,” the company said. AREG8-81WS (monostatic – single antenna) and AREG8-81WD (bistatic – dual antenna) are for the 76 to 81GHz band and are updates on the 4GHz AREG8-81S and …D. These work ...

Rohde & Schwarz is aiming at 6G and sub-THz research with W-band front-ends for an IF vector signal generator and a D-band thermal power sensor. SFI100A wideband IF vector signal generator The SFI100A wideband IF vector signal generator has been developed for early 6G research, high capacity wireless backhaul, fixed wireless access and automotive radar. With an RF modulation bandwidth ...

Yokogawa has announced a high-resolution extension to its DLM5000 series of scopes, with 12bit eight channel instruments at 500MHz and 350MHz bandwidth. Max sample rate is 2.5Gsample/s. “The DLM5000HD series expands Yokogawa’s oscilloscope lineup with models that deliver higher resolution for more accurate waveform analysis, and come with features that improve usability and enable easier setup,” according to the company. ...

GaGe has filled out its line of PCIe digitiser boards – essentially ADCs for PCs – with three new dual-channel models: one with with 250MHz bandwidth and 14bit 500Msample/s sampling, and two 125MHz 250Msample/s models, one with 16bit resolution and the other 14bit. The “digitisers boast ENOB [effective number of bits] of ~11+ typical”, according to the company. Inputs are ...
