Product Detail

SA1000 1.1 GHz EMC ANALYSER
 

A high performance, high specification analyser for compliance measurements with advanced Windows software.

The SA1000 with EMCEngineer software offers the most powerful and affordable system available for both compliance and pre-compliance emissions measurements. It even includes a TestDirector mode which invokes an ‘expert system’ to help decide which EN standard and limit level applies to your product, then prompts you through the complete test procedure, controlling the analyser automatically.

The SA1000 is unique in the way it combines the speed and functionality of a spectrum analyser with the accuracy of an EMI receiver. When used with the ERS for radiated emissions testing, it will even automatically compensate for test site errors and distortion.

Features

10KHz to 1.1GHz coverage

Fully PC controlled

EMC compliance tests to EN standards

True average and quasi-peak measurements

Powerful PC based software with TestDirector Expert System to assist testing.

Unique single frequency mode for non-steady emissions

Auto compensation for test site errors when used with the ERS

Auto limit level adjustment for antenna distance.

Auto antenna factor compensation

POWERFUL The SA1000 is capable of displaying the spectrum over any part of the range 10KHz to 1100MHz with complete freedom of start and stop frequencies, with either logarithmic or linear scaling. This exceeds the range required to cover the EMC spectrum for all the common standards.

AFFORDABLE The unique SA1000 is the only analyser (at any price) which is totally PC controlled and yet covers all the requirements of EMC testing such as antenna factor compensation, standard limits with adjustment for distance, overload detection etc... It represents an outstanding price/performance advantage.

UNIQUE The SA1000 has a single frequency mode for true averaging and quasi-peak measurements which can be shown plotted against time. This enables trends and excursions to be monitored as required by the EMC standards for fluctuating emissions

EFFECTIVE The system software is specifically designed for EMC measurements and comparisons with limit levels. Standard features include background nulling, antenna factor compensation, limit line display and multiple trace comparison.

KEY SPECIFICATION

HARDWARE The SA1000 analyser is an exceptionally well featured, EMC analyser which is completely controlled from your own PC. 10KHz - 1100MHz frequency range. High sensitivity. Field strength down to <17dBuV/m when used with the Laplace RF200 broadband antenna. 70dB dynamic range. Peak. Quasi-peak and average detectors 4 stage input attenuator, 0, 10, 20 and 30 dB Infinite zoom capability. Tune to any signal anywhere in frequency range. 9KHz and 120KHz I.F. bandwidths (CISPR compliant). Monitor any signal in Single Frequency mode. Built-in calibration source to confirm operation and accuracy of analyser. An audio demodulator complete with internal loudspeaker is provided so that the user can listen to any signal. This aids both identification of signals, particularly background, and the location of problem emissions. The demodulation technique copes with FM and AM modulation.

 

EMCEngineer - EMC software for Windows Powerful software system specifically developed for use with the SA1000 Spectrum analyser and the Laplace EMC test kits. Includes many unique features designed to make EMC testing as simple and painless as possible, including a TestDirector mode which, as far as is practical, automates the measurement of EMC emissions. Selection of the correct analyser parameters, limit lines, compensation factors is automatic and the screen will prompt the operator with instructions for each stage of the test. The EMCEngineer software has been tailored to suit the needs of users who are using open area test sites and thus have to contend with relatively high ambient levels of interference. The background nulling facilities enable the user to identify signals from the EUT amongst the ambient noise with ease. To make the operation as simple as possible, the software automatically compensates for antenna factor, adjusts limit lines to match test distance and detector type and can display up to 4 traces on screen simultaneously. Installation is straightforward and automatic. The system uses the serial port (which all PCs have) so there is no need to plug anything inside the PC. Because the system is PC based all the resources and facilities of the PC environment are available to the user. These include saving of test results to disk, hardcopy printing, transfer of data to other applications, merging of results into test reports etc..
