Spirent GSS6450
The world’s rst highly portable high bit
depth RF record & playback system
The GSS6450 from Spirent
takes RF record & playback
systems to a whole new level
of performance and exibility.
Battery powered and housed
in a small and portable case,
the GSS6450 can record any
RF in the 100MHz-6,000MHz
frequency range—including
any current GNSS signal,
2.4GHz and 5GHz WiFi, and
Cellular. With the capability
to record at up to 16 bits ‘I’ &
16 bits ‘Q’ and the exibility
to select any band of up to
80MHz within the frequency
range, the GSS6450 can be
congured to meet your
testing requirements—even as
they evolve.

Spirent GSS6450
A Simple Way to Test Multiple GNSS and other RF Signals
Testing RF signals such as GNSS, WiFi, and Cellular under real world conditions has
typically been complex and expensive—but not anymore. With the Spirent GSS6450
Record & Playback System (RPS) it’s quick and simple to record real RF signals for
playback in your test environment.
The exibility of the GSS6450 to record multiple RF signals on multiple RF interfaces
enables chipset and device developers from a variety of application areas to test
comprehensively. Once RF data is captured, the RPS is used in the lab to replay the
captured environment repeatedly to the device under test—allowing you to save
on project, travel, and engineering costs, whilst improving product performance,
quality, and time to market.
High Fidelity Record & Playback
The GSS6450 is designed to capture complex environments with the delity to
ensure that playback results in the laboratory are truly representative of captured
real world conditions. The exible structure makes it suitable for everything from
commercial application testing to interference and jamming test scenarios. The
4-bit option allows you to keep data storage levels down, whilst the 16-bit system
provides 80dB of dynamic range. Selectable recording bandwidth also allows the
user to ensure only the bands they are interested in are recorded, saving data space.
Big Performance from a Small Box
The self-contained unit has everything you need to start testing. Weighing just 2.2kg
and supplied with a shoulder strap, the GSS6450 can be either carried or used in
a vehicle. Simply connect the supplied antenna and press the one-touch record
button to start, and then select the le and press Play to replay at RF. An internal
1TB hard drive and an additional removable 1TB drive, along with up to 1.5 hours
of battery life, allows you to carry out uninterrupted recording in the eld. For users
requiring more storage, the unit supports larger capacity SSD and RAID devices.
The GSS6450 offers true recording exibility at variable bit depths (2, 4, 8, or 16),
and a choice of ve bandwidths (10, 30, 50, 60, or 80MHz). What’s more, a basic
conguration can be easily upgraded to support greater bit depths and more
constellations, bandwidths, and RF interfaces—if and when you need them.
Spirent’s future-proofed GSS6450 allows you to perfect the next generation of
GNSS enabled products.
