HS1001B - 1GHz RF Synthesizer - Ultra Low Phase Noise

January 17, 2011


The HS1001B is a single channel CW source that has industry leading phase noise performance of -150dBc/Hz at 100MHz (10kHz offset). The phase noise at 1GHz is -130dBc/Hz (10kHz offset). Holzworth products are 100% phase noise tested for final performance verification.

The HS1001B is designed with ultra fine tuning resolution for applications where precision is key. The tuning bandwidth of 8MHz to 1.024GHz can be controlled in tight 1mHz steps. The output power of -110dBm to +15dBm can be tuned in steps of 0.1dB. The phase offset tuning resolution is 0.1 degrees over a range of zero to 360 degrees.

Output spectral purity is excellent. The HS1001B was designed to meet the standards expected of a laboratory grade reference source. As a result, the typical output harmonic performance is -38dBc, while the typical output spurious performance is -65dBc.

Modulation functionality includes DC coupled FM, AM, Phase and Pulse modulation. With a tuning speed of 1ms that can be increased further by preloading command lookup tables, the HS1001B synthesizer is ideal for numerous applications, including those which require frequency hopping capability.

The compact form factor was a focal point of the overall design. The HS1001B was designed not only to be highly robust, but having a small form factor removes many challenges from the system integration process. Furthermore, the HS1001B is a 100% portable instrument that requires no AC power when using an optional dual USB cable.

Holzworth synthesizers are USB instruments that utilize the HID (Human Interface Device) platform as it is proven to be extremely robust, non-problematic and requires no installation of drivers. Synthesizer control is achieved via proprietary software, LabVIEWTM, MATLABTM or any command code that can access a device DLL file.
