Handheld RF spectrum analyser sets new
price point
As well as being lower in cost, the PSA1301T is considerably smaller and lighter and consumes less power than other RF spectrum analysers currently available.
TTi (Thurlby Thandar Instruments) has launched a new handheld RF spectrum analyser which, at a cost of only GBP 795, sets a new low price point for such products As well as being lower in cost, the PSA1301T is considerably smaller and lighter and consumes less power than other RF spectrum analysers currently available

Portable spectrum analyser goes online
The PSA1301T field portable spectrum analyser now includes the facility to e-mail screen images back to the office.
Handheld analyser aids RFID surveys
Upgraded handheld spectrum analyser is billed as an ideal tool for companies making site surveys for UHF RFID applications.
Despite this, it offers a high-resolution (480 x 320 pixel) backlit colour TFT display.
It achieves its combination of low cost and high performance by incorporating a handheld computer within the analyser.
This provides the display, control, calculation, mass storage and external interface capabilities of the product.

A limit-line editor enables any number of limit lines to be created and stored, which can be of considerable assistance in applications such as precompliance EMC testing.
Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
Programmable power-supplies offer outputs to 1kW
The XHR range of programmable power supplies, offering output ratings up to 1 kW is power-factor corrected for low current draw and reduced generation of input current harmonics.
The PSA1301T has a frequency range of 150kHz to 1.3GHz with selectable resolution bandwidth down to 15kHz.
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 1kHz 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 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.
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.
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 unit.
Low power consumption means that the instrument can operate continuously for more than four hours 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.
It will now make it practical for an engineer to carry a spectrum analyser to areas that have traditionally been difficult to access with benchtop 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 area 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 TX 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 built-in 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 e-mail access via Bluetooth and Wi-Fi.
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 0.5kg and measures 170 x 97 x 47mm.
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.
