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.

FAQ
The USG will not connect to the PC.
If you are running a Windows system, make sure that the USG USB
driver has been installed correctly, see page 16 for details. If you are
running Windows 8, please make sure that “Device driver
signature enforcement” is disabled before installing the driver, see
page 18 for details.
Primary RF will not allow me to connect to the GSP-730.
Make sure that all the USB cables from the USG and GSP-730 are
connected correctly, then make sure that the NI.488.2 software is
installed before Primary RF is installed. See page 20 for installation
details.
The performance does not match the specification.
Make sure the device is powered On for at least 30 minutes, within
+20°C~+30°C. This is necessary to stabilize the unit to match the
specification.
