Siglent SSG3021X-IQE Plus 2.1GHz RF Generator

The Siglent SSG3021X-IQE Plus is an advanced, reliable, and cost-effective RF signal generator designed for demanding communications, research, and electronic manufacturing applications. Covering a continuous CW frequency range from 9 kHz up to 2.1 GHz and an IQ modulation range from 10 MHz to 2.1 GHz, this instrument delivers accurate and stable signals for rigorous RF testing. Along with standard analog modulation formats such as AM, FM, and PM, and high-performance pulse modulation, this specific "-IQE" model supports external IQ modulation when paired with a baseband generator like the Siglent SDG6000X, making it an ideal choice for complex digital modulation tasks.

Built for durability and ease of use, the instrument is housed in a compact benchtop enclosure with integrated protective bumpers, making it ideal for both laboratory benches and automated test racks. The user interface is driven by an intuitive 5-inch capacitive touchscreen with an 800x480 resolution, which, along with a physical keypad and full USB mouse and keyboard support, provides a seamless user experience. With built-in support for USB power sensor leveling control, the unit offers flexible and powerful test integration via standard USB and LAN connectivity.

Product Features

External IQ Modulation Capability

Designed for advanced communications testing, the SSG3021X-IQE Plus features dedicated baseband inputs to support external IQ modulation. When combined with an external baseband source like the Siglent SDG6000X series, it can generate complex digital communication signals (such as QPSK or 16QAM) with exceptional Error Vector Magnitude (EVM) performance for evaluating receiver limits and digital RF links.

Excellent Phase Noise and Pure Signal Output

Delivering an ultra-low typical phase noise of -117 dBc/Hz at 1 GHz (20 kHz offset) and harmonic suppression below -30 dBc, the generator supplies exceptionally clean CW carriers for receiver sensitivity and selectivity testing. For maximum stability and accuracy over time and temperature variations, the generator can be upgraded with a high-stability OCXO clock reference.

Broad Output Level and Power Meter Control

The RF output level is fully adjustable from -110 dBm to +13 dBm, with a maximum output capability reaching up to +20 dBm (typical). The instrument also features full support for USB power meter control, allowing you to connect a compatible power sensor directly to the generator for accurate measurement, automatic level control, and easy two-tone testing configurations.

Intuitive Touchscreen and Flexible Connectivity

A bright 5-inch capacitive touchscreen provides an immediate visual overview of the entire signal path and all modulation parameters at a glance. The instrument integrates rapidly into automated systems via USB Host, USB Device (USBTMC), and LAN (VXI-11, Socket, Telnet), and also supports direct web-browser remote control for convenient operation without installing specialized software.
