QuickSyn Lite
NI's QuickSyn microwave frequency synthesizers are now available in an even more compact size (4 x 4 x 0.8 inches). The new FSL-0010 and FSL-0020 (10 GHz and 20 GHz synthesizers respectively) employ the revolutionary phase-refining QuickSyn technology, which allows this line of signal sources to perform with remarkably low phase noise, switch between frequencies very quickly, and consume power efficiently.
The new Quicksyn Lite synthesizers are less than half the size of the full featured models, yet they perform with wide coverage (0.65 to 10 GHz and 0.65 to 20 GHz), fine resolution (0.001 Hz resolution), fast frequency switching (100 μs), and exhibit instrument-grade spectral purity. Furthermore, the FSL-0010 and FSL-0020 include SPI and USB control interfaces, and like all QuickSyn synthesizers, these new models are immediately deployable by connecting them to a PC and power source. A soft front panel allows the user to access frequency sweep and list mode.
Instrument designers restricted by reduced footprint goals, power consumption constraints, and the need for low phase noise will appreciate the QuickSyn Lite synthesizer as the single solution to a multitude of design challenges. Moreover, these synthesizers are amazingly affordable!

1. In 2011, National Instruments (NI) acquired Phase Matrix, a well-established manufacturer of RF/microwave instruments, sub-systems, and components. Phase Matrix had previously developed the popular QuickSyn frequency synthesizers, many of which are used in a variety of applications within the RF/microwave industry.
2. In 2014, NI changed the branding of the QuickSyn product line by replacing the Phase Matrix logo with the NI logo. In some cases, as we deplete our stock, you may observe that the Phase Matrix logo still remains on packaging, software, manuals, and the unit itself. Other than the mere change of the logo, QuickSyn products employ the same revolutionary phase-refining technology that enables blazing-fast switching speeds and very low-noise and spurious performance in a compact package.
3. All QuickSyn products are RoHS compliant

Software
USB Front Panel GUI Installation File
For Windows
To use the QuickSyn USB interface on Windows-based computers, you will need to install QuickSyn USB driver software. This driver software allows you to communicate with the synthesizer through a regular com port and facilitates easy communication from programs that you write. The driver supports both 32- and 64-bit versions of Windows XP, Windows Vista,
and Windows 7.
Downloadable Zip File (both 32- and 64-bit files included)
Zipped QuickSyn USB Driver File
Note: Driver installation instructions are available in the QuickSyn user's manual
Linux Users
Linux users do not need to download files to communicate with the QuickSyn synthesizer. However, the following setup is necessary.
1. Plug the QuickSyn synthesizer into a USB port and open a terminal window.
2. At the command prompt, enter cat /proc/bus/usb/devices
Example of data returned with no driver loaded:
T: Bus=05 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=02(comm.) Sub=00 Prot=00 MxPS=64 #Cfgs= 1

E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
To load the generic USBSerial driver, enter the following string: modprobe usbserial vendor=0x213e product=0x000a
Note: you must have the correct permissions to use modeprobe.
4. To view the loaded driver, enter cat /proc/bus/usb/devices
Example of returned data with driver loaded:

5. You can now communicate with the QuickSyn synthesizer from the command prompt in the terminal window by redirecting the output to the USB device.
For example, to turn on the RF output, enter echo 0F01 > /dev/ttyUSB0
6. You can query settings by redirecting the USB input to standard input like this:
echo 04 > /dev/ttyUSB0 | head < /dev/ttyUSB0 which will read back the frequency.
