General Description
The AR2010 RF synthesizer series from Applied Radar, Inc.
offers a low cost solution to today’s demanding RF signal
generation needs.
The AR2010-4400 RF Synthesizer Module is a low-cost,
wideband 138MHz to 4.4 GHz frequency synthesizer ideally
suited for bench top test and measurement as well as lowcost small form-factor radar and communications systems.
Its wide output frequency range, superb spurious rejection,
and excellent phase noise performance provide a highquality, low-cost alternative to bench top RF signal
generators. An internal reference allows the unit to operate
without any external components, but also has an input for
an external reference.
The synthesizer module is powered and controlled directly
by a host PC through USB. The AR2010-4400 is VISA
compliant, enabling seamless cross-platform use.
The USB stick design is small enough to even fit in your
pocket!

Integer and Fractional Modes of Operation
The AR2010 RF Synthesizer Module is capable of operating in integer or fractional mode. When in integer
mode, the frequency resolution of the Synthesizer Module is calculated using equation (1):
(1)
Fractional mode will allow for a frequency resolution of 2.441 kHz at a 10MHz reference frequency. Lowering
the reference frequency will improve frequency granularity but will degrade phase noise performance. Raising
the reference frequency will degrade the frequency granularity but will improve phase noise performance.
In general, integer mode will exhibit better phase noise and spurious performance than fractional mode across
the synthesizer’s entire frequency band. It is recommended to use integer mode over fractional mode
whenever possible.
Frequency Reference Consideration
Aside from reference divider considerations, the phase noise performance and stability of the reference
oscillator is closely related to that of the RF Synthesizer Module. It is important to choose an accurate and
stable reference in order to ensure the best possible performance of the AR2010. The AR2010-4400 comes
with an internal reference for operation without the need of an external reference. However, phase noise can
be improved with a more stable external oscillator.
Programming Interface
This module can be controlled using any computer with a USB port running the Windows, Macintosh, or Linux
operating systems. Other configurations may be possible since the synthesizer uses the USB Test and
Measurement Device (USBTMC) class standard to emulate a GPIB bus. This enables it to easily interoperate
with an existing test equipment setup. A Windows compatible USBTMC driver is supplied with the module.
Most newer distributions of Linux already have USBTMC drivers included in the kernel, and Macintosh users
will need to obtain drivers from a third party. Installation of drivers is not necessary if you already have a
compliant VISA runtime installation, such as one provided by National Instruments or Agilent. A demonstration
interface program using the VISA runtime is provided with the module.

The module is controlled by delivering text-based commands to it through the USB interface. The structure of
this command language is compliant with the SCPI 1999.0 standard and is detailed in the programming
manual associated with this device. For further information on programming the AR2010 RF Synthesizer, see
the USB Programming manual (AR2010-99-2).
