Model 870A | 10 MHz to 54 GHz Single or Multi Channel Signal Generator
Our most current rf/microwave signal generator, the Model 870A, designed to deliver exceptional agility and phase noise performance across an extremely wide frequency range making it a go-to tool for engineers tackling high-frequency challenges.
- Broad Frequency Span: Continuous coverage from 100 kHz to 54 GHz with ultra-low phase noise for clean, precise signals in demanding applications.
- Fast Switching Options: Standard switching as low as 500 μs; add the Fast Switching (FS) option to drop to 15 μs—ideal for frequency-agile systems and time-critical tests.
- Superior Signal Purity: Advanced output filtering minimizes harmonics and spurious signals, ensuring high-fidelity output even at microwave and mmWave frequencies.
- Intuitive Touch-Screen Control: Redesigned front-panel interface that simplifies setup and operation, whether you’re working standalone or in a production environment.
- Flexible Multi-Channel Configurations: Available in 1, 2, 3, or 4 channels; multi-channel models fit neatly in a compact 19″ 1U rack-mount enclosure for easy scaling.
- Seamless Connectivity: Ethernet, USB, and GPIB interfaces support integration into automated test setups, lab benches, or research systems.
This ultra-low phase noise signal generator supports a wide range of real-world uses, including radar and electronic warfare development, 5G/6G component testing, satellite communications, quantum research, and high-speed production verification. Its combination of wideband coverage, rapid switching, and clean output makes it especially valuable when signal quality and speed cannot be compromised.

The key difference between LN and LN+ is that LN+ will have better long-term performance—for example, a better Allan variance for a longer time. For short-time performance, they are identical.
Here’s another example…Option LN adds a 100 MHz OCXO on the ref board, applying to all channels. Option LN+ will do the same. The only difference is that the OCXO will have better long-term stability.
You can incorporate either LN or LN+. Options can’t be combined and priced per unit.
