USG Series Introduction
The USG series signal and tracking generators can be operated as
standalone continuous wave generators, or when paired to a PC
and the GSP-730 spectrum analyzer, they can be used as tracking
generators.
As continuous wave generators, the USG can be configured using
any java supported PC or an Android device. The device can
generate continuous wave, sweep, power sweep and frequency
hopping waveforms.
As a tracking generator, the USG can be connected to a PC using
dedicated software (Primary RF) to synchronize the USG with the
GSP-730 spectrum analyzer.
Series lineup
The USG series consists of 5 models, spanning a number of
different frequency ranges.

First Time Use Instructions
The following instructions will go over all installation instructions
that are required to operate the USG from a PC or from an android
device.
Installing the USG USB Driver
Description
The USG connects via USB to a PC using a
virtual COM port driver.
For Linux and OS X systems, the USG device is
recognized as a virtual COM port device
automatically. A device driver does not need to be
installed for these systems.
For Microsoft Windows operating systems, the
USG will be recognized as a virtual COM port
device only after the USB driver is installed.
Requirements
Operating System: Windows XP, Vista, 7, 8*
Note
*Please note that for Windows 8, “Device driver
signature enforcement” must first be disabled
before the driver can be installed. See page 18 for
details.
Steps
1. Connect the USG to the PC using the USB Type
A - Mini-B cable.
If the PC asks for the driver, please go to step 5.
2. Open the Windows Device Manager. On
Windows 7 for example:
Start>Control Panel>Hardware and Sound>Device
Manager
