Anritsu 69B Series Synthesized Signal Generators
3 models with full specifications from Anritsu.
The Anritsu 69B Series of synthesized signal generators is designed for RF, microwave, and automated test equipment (A.T.E.) applications requiring high performance and spectral purity. Covering frequency ranges up to 20 GHz or 40 GHz, these instruments provide robust analog modulation, extensive sweep modes, and low phase noise. This guide outlines the key performance profiles of the 69367B, 69167B, and 69317B models to help engineers select the appropriate instrument for advanced signal simulation and system integration.

Frequency Ranges and Resolution Extensions
The 69B Series offers versatile frequency coverage. Both the Anritsu 69367B and Anritsu 69167B operate across a standard frequency range of 10 MHz to 40 GHz, with low-end extensions down to 0.1 Hz available via Option 22 on the 69367B and Option 4 on the 69167B. The Anritsu 69317B provides a maximum frequency of 20 GHz, starting from a base minimum of 10 MHz.
All three models feature a standard frequency resolution of 1 kHz. For applications demanding tighter frequency increments, the resolution can be upgraded to 0.1 Hz. This upgrade is achieved via Option 11 for the 69367B and 69167B, and Option 10 for the 69317B.
Phase Noise and Spectral Purity
For applications where phase noise is critical, the models offer distinct performance tiers. The standard Anritsu 69367B provides phase noise of <-100 dBc/Hz at a 10 kHz offset with a 10 GHz carrier. In comparison, the standard Anritsu 69167B delivers <-88 dBc/Hz under identical conditions, but can be configured with Option 3 to lower phase noise to <-103 dBc/Hz.
The Anritsu 69317B utilizes an internal 10 MHz oven-controlled crystal oscillator (OCXO) as its reference source, achieving a stability of less than 2 x 10^-8 per day after warmup. It can also interface with external reference frequencies of 1, 2, 5, or 10 MHz.
Modulation Capabilities and Setup Storage
Each instrument supports complex signal modulation. The 69367B supports AM, FM, Phase, Pulse, Scan, and user-defined modulation types. The 69167B and 69317B models provide standard AM, FM, Phase, and Pulse modulation. The 69167B can also be equipped with Option 10, adding an internal pulse generator featuring a pulse width range of 50 ns to 65 ms, a pulse delay range of 0 to 65 ms, and a 100 ns resolution.
For workflow efficiency, the 69167B and 69317B allow engineers to save and recall up to 10 complete front-panel setups or operating states directly from memory, simplifying repetitive testing routines.
Frequently asked questions
- What is the difference in maximum frequency coverage among the 69B Series models?
- The Anritsu 69367B and Anritsu 69167B cover frequencies up to 40 GHz, whereas the Anritsu 69317B supports a maximum frequency of 20 GHz.
- How low can the frequency resolution be adjusted on these signal generators?
- All three models have a standard frequency resolution of 1 kHz. This can be extended down to 0.1 Hz using Option 11 on the 69367B and 69167B, or Option 10 on the 69317B.
- Which model offers the lowest phase noise configuration?
- The Anritsu 69167B can achieve <-103 dBc/Hz at a 10 kHz offset (10 GHz carrier) when equipped with Option 3. For standard configurations without options, the Anritsu 69367B offers the lowest phase noise at <-100 dBc/Hz.
