lessUSB performs in the real
world, and to experiment with
module-driven designs.
The CY3630 Evaluation Kit
(EVK) showcases the robust, lowpower
WirelessUSB LP radio,
and includes a multiconfiguration
microcontroller (MCU)
socket, radio modules, LCD displays,
a large prototyping area,
and MCU programming software.
The kit also includes four
firmware tutorials as well as a
wireless range demo that help
users to quickly build familiarity
with the features and performance
of the radio.
WirelessUSB LP offers an unparalleled
feature set to enable
superior interference immunity,
low bill-of-materials (BOM) costs,
higher data rate applications,
and faster time-to-market for keyboards,
mice, gaming devices,
presenter tools, and remotes, as
well as other simple, multi-pointto-point
wireless applications. It
operates between 1.8 and 3.6
volts, using advanced power-saving
techniques to extend battery
life in devices such as wireless
mice. The device uses Cypress’s
patented frequency agile Direct
Sequence Spread Spectrum
(DSSS) technology to offer bestin-class
interference immunity for
a 2.4-GHz radio system. This
combination of low power consumption,
interference immunity
and low cost make it ideal for
wireless HID applications.
The CY3630 WirelessUSB LP
EVK includes all of the following
items:
• Microcontroller modules for
driving the radio
• An Emulation module for incircuit
debugging
• WirelessUSB LP radio modules
for easy prototyping and
evaluation
• MiniProg Programmer for insystem
serial programming of
any Cypress Flash MCU
• LCD Modules to display application
data and provide user
feedback
• CD-ROM with complete kit
documentation, tutorials, and
sample firmware

Handheld RF spectrum analyzer based on Palm handheld
Thurlby Thandar Instruments has
developed a handheld RF spectrum
analyzer designed to set a
new price point - below € 1200
(approx. £ 850). The analyzer
is based around a Palm handheld
computer which provides
the display, control, calculation,
mass storage and external interface
capabilities.
The PSA1301T has a high-resolution
(480 x 320 pixel) backlit
color TFT display capable of displaying
65,000 colors but still
has a relatively low power consumption
providing more than 4
hours continuous operation from
a single charge. For continuous
bench top operation it can be
operated from its AC adaptor
which also recharges the batteries
in less than 4 hours.
Frequency range is 150 kHz to
1.3 GHz with selectable resolution
bandwidth down to 15 kHz.
Sweep modes include continuous,
single, peak hold and average
(up to 256 sweeps). Sweep
parameters can be set in terms
of centre plus span or start plus
stop to 1 kHz resolution. A zero
span mode with AM or FM
demodulation is also provided.
Dual markers are incorporated
with simultaneous readout of
absolute amplitude and frequency
plus difference values.
Markers can be scrolled manually,
or set to automatically find
and track peaks.
A reference trace can be displayed
simultaneously with the
live trace, with the two traces
clearly differentiated by color.
The reference trace is automatically
shifted and scaled to match
the current sweep parameters
when they are changed.
Any number of waveforms and
settings can be stored to permanent
memory using an SD or
MMC flash memory card. Data
can be saved under default or
user-entered file names as preferred.
bitmap images of the
whole screen can also be stored
for viewing or printing. The
PSA1301T can store three types
of data: traces, set-ups and
screens. Trace data is stored as
tables of amplitude against frequency
in a comma delimited
format, which can be recalled to
the screen as a reference trace.
Screens are saved as complete
bit-map images of everything visible
at the time (traces, graticule,
markers and all annotation).
These can then be viewed on the
Palm itself or transferred to a PC.
PSA1301T data files are stored
on removable flash memory
cards. A USB linked card reader
is supplied which allows files to
be transferred to or from a PC
using simple drag and drop.
Where a wireless connection is
available (Bluetooth or WiFi),
files may be transferred using
email attachments or via a wireless
communications application.
PSA1301T trace files have a
standard comma separated
value (.csv) format which can be
imported into other applications
such as Excel or MathCad. Control
of the analyzer is provided
by soft keys created on the touch
screen. These are large enough
to be finger-operated, eliminating
the need for a stylus. Alternatively,
all functions can be
operated using the hard keys of
the handheld unit.
To extend battery life the analyzer
can also be set to turn off
automatically after a user-defined
delay from the last key press.
