Siglent signal generator reaches 6GHz

Siglent SSG5000X-V is a 6GHz signal generator with vector capability “which now gives the company RF generators that address the complete sub-6GHz communication frequency range. This includes the latest NR-5G Band [FR1], which is located between 3.4 and 3.7GHz”, according to Siglent.

Phase noise is -120dBc (1GHz 20kHz offset) with regulated maximum output to +20dBm (settable up to +26dBm) and minimum to -130dBm (settable to -140dBm). An optional OCXO-module upgrades temperature stability. Differential I and Q baseband outputs are available – there are four BNC connectors on the back, and there are I and Q baseband inputs to support external IQ-Modulation. “Therefore, it is possible to use the generator in all stages during the RF transmitter or receiver design,” said the company.

Multi-tone mode generates two or more tone signals by selecting the number of tones and spacing for audio measurements, amplifier non-linear distortion tests and receiver non-linear distortion tests.

Modulation schemes including ASK, FSK, PSK and QAM are available with a symbol rate up to 120Msample/s. “In complex test cases that require multi-carrier, OFDM modulated signals, like those used in digital broadcast, wireless or cellular telecommunication systems, the ARB mode delivers the desired waveform,” claimed Siglent. Protocols including 5G NR, LTE, WLAN, WCDMA, GSM, and Bluetooth are built-in, and custom ARB files can be created to implement further proticols. Additive white gaussian noise (AWGN) can be generated within the instrument.

User interface is through a 5” touch display, and there is a web server for remote control over Ethernet.

SSG50000X is a less capable 4GHz version without IQ capability, that can be upgraded to 6GHz by software license key.
