The high-performance, modular RF analog signal source RSG3745 empowers precision testing to new heights.

• The frequency coverage ranges from 9 kHz to 45 GHz, supporting an output frequency step of just 0.01 Hz and a minimum pulse width as low as 100 ns, meeting the full-frequency-band requirements—from basic low-frequency verification to cutting-edge microwave and millimeter-wave applications.

• The phase noise is below -105 dBc/Hz at a 10 kHz offset—a specification that is particularly critical for high-frequency signal sources. The output power range spans from -100 dBm to +10 dBm, with power accuracy within ±1 dB, providing users with ample test margin.

• Adopting a dual-slot 3U PXIe modular architecture, this system leverages the standard PXI bus to easily achieve multi-channel synchronization and scalability. Channel frequency and power are independently adjustable. The entire system consumes less than 30W and weighs no more than 1.2kg, striking a balance between high integration, high reliability, and expandability.

• Not only can it precisely generate continuous-wave (CW) signals, but it also fully supports various analog modulation modes such as AM, FM, and PM, enabling flexible simulation of complex signal scenarios and catering to diverse needs including communication protocol testing and radar signal simulation.

The reference clock supports both internal and external synchronization at 10 MHz/100 MHz. The external reference input power ranges from 0 to 5 dBm. The internal clock can be output externally, enabling clock synchronization among multiple devices.

The RF output uses a 2.92 high-frequency connector (50Ω); the remaining control interfaces are SMA-K, and the PXIe interface enables integrated power supply and programmable control.

The accompanying host computer software supports full-featured operations such as device reset, parameter configuration, and status monitoring. It provides a clear UI interface and a comprehensive API function library, making it easy to integrate into automated testing.

Based on the PXI architecture, users can easily achieve multi-channel expansion and build complex test systems. The channel frequency and power are independently adjustable, significantly enhancing testing efficiency.

It serves as a core tool for applications in areas such as wireless communications (5G/millimeter-wave), satellite communications, radar systems, and semiconductor device testing, enabling receiver sensitivity verification, power amplifier testing, complex signal simulation, and component characteristic analysis. Its PXIe modular design makes it easier to integrate into automated test systems, providing a cost-effective, domestically produced precision testing solution for high-end R&D and manufacturing.

Test engineers no longer need to deal with complex-to-operate and difficult-to-maintain imported equipment. With just one RSG3745 signal source, a standard PXIe chassis plus controller, and simple host computer software, you can build a complete solution—from R&D validation to production-line testing.

In the past, using imported equipment not only involved high procurement costs but also often required waiting several weeks for after-sales support. After switching to the RSG3745, not only do the key parameters fully meet our requirements, but the device also integrates seamlessly with our existing PXI system, significantly boosting testing efficiency.

More importantly, Semi-mile Measurement & Control boasts a professional technical support team that provides end-to-end services, including on-site support, equipment calibration, software upgrades, and even customized testing solutions. This dual guarantee—combining “hardcore products with soft services”—is precisely the new experience offered by domestically produced high-end instruments.
