The Holzworth HSM Series RF Synthesizer Modules are stand alone, CW sources. These sources are designed as building blocks for systems integration where performance at the foundation is critical. Holzworth synthesizers provide incredible signal stability. When integrated as multiple units connected to the same reference signal, a phase coherent relationship is created which provides optimal unit-to-unit stability.

The core architecture of the HSM Series modules is derived from Holzworth’s proprietary NON-PLL design to provide the ultimate in phase / frequency stability. This direct-digital/direct-analog hybrid design was originally developed as a key building block for our phase noise analysis products. The hybrid architecture provides frequency agility & resolution, phase continuous switching and predictable performance without compromising on spurious or phase noise performance.

 

HSM SERIES SPECIFICATIONS

 

HSM SERIES FREQUENCY SWITCHING SPEED

The frequency switching speed of the HSM Series is faster than most. Unlike PLL based architectures, the non-PLL based HSM Series does not exhibit any significant settling time after a frequency change. Settling time is not always clearly specified in PLL based synthesizer datasheets even though it is often a large contributor to the overall switching speed.

 

BURST MODE SELF PULSE MODULATION

Pulse modulation "burst mode" does not require an external stimulus signal. The programmable self pulse modulation function exhibits very fast rise and fall times with minimal overshoot or ringing.

The screen shot shown here demonstrates an approximate 10ns risetime (Tr) when operating at a frequency of 500MHz. The pulse width is approximately 100us in this example.

 

COMMAND / CONTROL

The native I/O interface for the HSM Series is via SPI, which is preferred for most integrated applications. When used with a USB Communications Module or an Ethernet Communications Module, these synthesizer modules can be controlled with the Holzworth Application GUI or directly via addressed command lines.
