1Overview
The Model 866-M is a compact, flange-mountable frequency synthesizer covering 1 MHz to 40 GHz with output power from -10 to +25 dBm. It switches in 85 µs with Option FS and holds SSB phase noise of -145 dBc/Hz at 20 kHz offset from a 1 GHz carrier, and -125 dBc/Hz at 10 GHz.
The module weighs about 1.3 lb and measures 6.5 by 2.4 by 1 inches, drawing roughly 20 W with passive cooling. It is controlled over Ethernet through graphical software or SCPI. Multiple units cascade in a master-slave arrangement for phase-coherent multi-channel operation.
2Key Features
- Small flange-mount module
- CW and pulse modulation
- Low power consumption, passive cooling
- Low phase noise
- Multi-channel configurable and cascadable in master-slave configuration
- Phase coherent across channels
3Frequency & Output Power
Coverage runs continuously from 1 MHz to 40 GHz. Output is settable from -10 to +25 dBm in 0.5 dB steps. Frequency resolution reaches 0.001 Hz, with calibrated accuracy of ±30 ppb and temperature stability of ±100 ppb across the 0 to 50 °C operating range.
4Phase Noise & Spectral Purity
SSB phase noise is specified at 20 kHz offset for two representative carriers.
| Carrier | Offset | SSB phase noise |
|---|---|---|
| 1 GHz | 20 kHz | -145 dBc/Hz |
| 10 GHz | 20 kHz | -125 dBc/Hz |
5Frequency Switching & Agility
Standard switching is 500 µs. Option FS brings switching to 85 µs for agile applications. Frequency resolution of 1 mHz and phase resolution of 0.1° support fine tuning and coherent phase control.
6Modulation
The 866-M provides CW and pulse modulation.
