Telonic Instruments adds Siglent RF instruments for comms developers

Siglent’s SSA5000A and SSG5000A RF instruments are now available from specialist distributor, Telonic Instruments. The SSA5000A spectrum analyser and the SSG5000A RF signal generator are significant because they extend Siglent’s RF instrument portfolio to address 20GHz+ frequencies.

The SSA5000A spectrum analyser has an operating range of 9kHz to 26GHz while the SSG5000A RF signal generator operates at 9kHz to 20GHz. Both instruments support X- and K-band measurements. The high-performance test equipment can be used by developers of equipment operating at frequency bands in the microwave range. Typical applications are high performance measurement in the development of satellite communications (satcom), radar and mobile communications systems. 

There are two models in the SSA5000A spectrum analyser series, providing fast spectrum analysis from 9kHz to 13.6GHz or 9kHz to 26.5GHz. They have a DANL of -165dBm/Hz and a low phase noise of 105dBc/Hz. For ease of use, they also have a large 12-inch touchscreen display. The SSA5000A analysers are suitable for test applications in the communications and IoT sectors, RF component and transmitter evaluation. The analyser measures EVM (error vector magnitude) and other transmission quality factors and includes eye-diagram and constellation graphing modes. Intermittent signals are captured using the optional real time (RTSA) mode. 

Analysis bandwidth is up to 40MHz. This makes transmission analysis of common protocols like Bluetooth and WLAN testing for IoT devices much easier, explained Telonic. 

The analysers are offered with a range of options, such as an EMI feature which delivers interference and electromagnetic pre-compliance measurements; analogue and digital modulation analysis (AMA / DMA) to enable common analogue (AM, FM); and digital (ASK, FSK, PSK, MSK, QAM) demodulation and analysis to accelerate debugging and design troubleshooting.

The analysers’ bandwidth and functions can be upgraded at a later date, as and when expansion is required.  

The second instrument, the SSG5000A RF/MW signal generator can output clean sine waves up to 20GHz. Key features are the spectral purity, low phase noise of -120dBc/Hz. When combined with power control, the signal generator is suitable for high frequency LO in high performance applications, for example in the fields of radar, quantum physics and RF component verification. 

Both frequency and level sweep functions allow faster testing and pulse signal generation is also integrated as standard. Coupled with Siglent’s SSG5000X-V vector signal generator, the SSG5000A can be used to test communications modules, confirmed Telonic.
