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 ...

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 ...

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 ...

RF instruments from Siglent, the SSA5000A spectrum analyser and the SSG5000A RF signal generator for satcom, radar and mobile comms developers are now available from Telonic Instruments. The SSA5000A spectrum analyser has an operating range of 9kHz-26GHz and the SSG5000A RF signal generator operates at 9kHz-20GHz. Both instruments support X- and K-band measurements for microwave frequency bands. Two models in ...

Yokogawa has launched two optical spectrum analysers that together can cover 1 – 3.4μm for product development and manufacturing. “AQ6375E and AQ6376E are the only grating based OSAs covering SWIR [short wave infra-red] over 2μm and MWIR [mid-wave] over 3μm with world class optical performance,” claimed the company, adding that they have “extreme optical precision to aid development of measurement ...

Audio Precision has improved loudspeaker and headphone analysis capability with version 6.1 software for its APx500 analysers. “Most importantly for the designers and manufacturers of speaker drivers, and products incorporating them, APx software now offers the broadest set of methodologies available for detecting rub and buzz defects,” according to the company, explaining: “Rub and buzz is a term commonly used ...

Microchip is aiming at engineers make accurate measurements of frequency signals, including those generated by atomic clocks and other high-performance frequency references with a phase noise analyser. Called 53100A, it works up to 200MHz and characterises the phase noise, jitter, Allan deviation (ADEV) and time deviation (TDEV) – with a variety of configurations by allowing up to three separate devices to ...

Rohde & Schwarz has some special offers on its entry-level scopes, spectrum analysers, power supplies and power analysers. The idea is that the deals, which last until the end of the year, include a lot of optional extras, which the customer pays for early at a reduced price rather than waiting to buy them later – the branding is ‘Everything ...

Rigol has added a vector signal analyser option to its RSA5000 series spectrum analysers, for characterising complex RF modulation schemes – including QAM, QPSK, ASK, MSK and FSK. “The VSA application gives engineers ability to utilise up to 13 integrated measurement functions including I/Q waveform and RF envelope, constellation and vector diagrams, symbol level decode, time and frequency, and bit ...

Red Pitaya has launched a vector network analyser (VNA) extension for its credit-card-sized plug-in STEMlab data acquisition hardware, which works with a host PC running Windows or Linux. It covers 500kHz to 62MHz, has a typical directivity of 42dB, a dynamic range of 74dB and a noise floor at 88dBm. Features of its companion software include: Smith chart, impedance, SWR, ...
