Ultra-Compact, General-Purpose Low Noise Synthesizer
Hands on workshop at APS
The 845-M is a wideband low phase-noise synthesizer operating up to 20 GHz. The module has a mili-Hz frequency resolution and uses a high-stability internal reference. The internal reference can be phase-locked to a programmable external reference.
The module has a USB and LAN interface and can be controlled using SCPI 1999 command sets. This small module operates with an external 6V DC supply and includes BNC’s SigGen GUI software package.
Features
• Low phase noise
• Fast Switching
• Wideband DC frequency modulation
• Internal OCXO reference
• Single 6V Supply
Applications
• ATE
• LO for frequency converters
• Telecom / SatCom
