Keysight AP4012A Frequency synthesizer 20 GHz (multi-channel)
Key Features and Functions
Keysight AP4012A FS1 is a multi-channel frequency synthesizer covering 8 kHz to 20 GHz with fast switching speed, good phase noise, and signal quality.
- Offers multi-channel options in 1-, 2-, 3-, or 4-channel configurations
- Each output can be programmed independently in frequency, phase, and power
- Comes in a standard 1U 19’’ rack-mountable enclosure, or an optional high isolation enclosure
- Works with a high-stability OCXO reference
- Uses a phase-coherent architecture to keep stable phase relationship between outputs
- Offers fast switching as low as 5 µs
- Programmable with standard SCPI syntax using USB or GB ethernet interface
- Enables synchronizing and triggering in real time with the fast control port (FCP)
Highlights
Multiple channels with ultra-fast switching options
The Keysight AP4012A FS1 is a multi-channel frequency synthesizer covering 8 kHz to 20 GHz. For high phase coherence, the unit locks RF channels to a common frequency reference. You can program each output independently in frequency, phase, and power.
In addition to good phase noise and signal quality, the AP4012A FS1 frequency synthesizer is also available with a significantly fast switching and sweeping option. With this option, you can complete switching transient in less than 5 micro-seconds over the entire settable range of the device.
