Programming Interface
The QM2010 series of RF synthesizers can be controlled using any computer with a USB port running
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 allows for easy integration into existing test setups. A Windows
®
compatible USBTMC driver is supplied
with the module. Most 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 lightweight GUI using the VISA runtime is provided with the module.
The synthesizer is controlled by delivering SCPI 1999.0 compliant text-based commands through the USB
interface. For command structure information and a full command list, see the USB Programming manual
(QM2010-99-2).
