TTi (Thurlby Thandar Instruments) has launched a
portable RF spectrum analyser which, the company claims, represents a
new price point for such products.
As well as being lower cost, the PSA1301T is
considerably smaller, lighter, and lower power than other RF spectrum
analysers currently available. Despite this, it offers a high resolution
(480 x 320 pixel) backlit colour TFT display.
It achieves this by incorporating a handheld
computer within the analyser. This provides the display, control,
calculation, mass storage and external interface capabilities of the
product.
The PSA1301T has a frequency range of 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 live trace, clearly differentiated by colour. 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. These 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.
Control of the analyser 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.
Low power consumption generates more than four hours
of continuous operation from a charge. The analyser can also be set to
turn off automatically after a user defined delay from the last key
press, extending battery life further.
The PSA1301T will offer RF service engineers a cost
effective and highly portable tool that will make it practical to a
carry a spectrum analyser to areas that have traditionally been
difficult to access with bench top instruments and not cost effective
when using existing portable products offered by other manufacturers.
This will reduce the need for a return visit when it is suspected that a
spectrum analyser is required.
Site testing for RFID is expected to be a popular
are for the PSA1301T. Availability of an ultra portable and low cost
spectrum analyser with full documentation stored in the built in
handheld computer will ensure that RF testing can be performed on any
site service visit.
The Palm T|X handheld used within the PSA1301T
provides the engineer with a versatile tool for recording site
information and visit results. Documentation for the products being
tested and test procedures can be stored on the handheld while
functioning within the PSA1301T.
Major applications include word processing and
spreadsheets (compatible with Microsoft Word and Excel), contacts and
appointments diary, multi-function calculator, picture viewing, audio
and video players, plus web and email access via WiFi and Bluetooth.
The price and performance offered by the PSA1301T
will also make it a valuable tool for engineers that have infrequent
requirements for a spectrum analyser. EMC evaluation testing and RF
interference caused by high-speed clock signals can be identified
quickly.
The PSA1301T weighs less than 0.5 kg (1.1 lbs) and
measures 170 x 97 x 47 mm (6.7 x 3.8 x 1.85 inches). The weight and
dimensions make it a true handheld instrument, unlike other portable
spectrum analysers which can be up to four times the size and weight.
The PSA1301T costs $1500 in the USA, £795 in the UK
and 1,195 Euros in Europe. |
