RF1000 Synthesiser (30MHz - 1GHz)
RF2000 Synthesiser (30MHz - 2.4 GHz)
 

PC controlled RF synthesisers for immunity testing up to 2.4GHz matched to the requirements of IEC61000-4-3 and featuring automatic scanning to pre-programmed schedules.

• Simple to use via PC 'windows' control software.
• USB port interface. No need for special interface cards.
• Field probe input for automatic level control.
• Suitable for use with any Power Amplifier and antenna / cell / chamber combination.
• Standard IEC61000-4-3 tests pre-programmed.
• EUT status input and prompt output.

 

The RF1000/RF2000 are signal sources matched to the RFI immunity requirements of IEC61000-4-3.
Features such as sine and pulsed modulation, programmable start and stop frequencies, frequency step, and dwell time are provided as standard.

These units are essentially the same except that the RF1000 covers the range 30MHz to 1000MHz and the RF2000 covers 30MHz to 2400MHz. Both include powerful Windows control software with USB port interface.

When used with the LaplaCell range of test cells, these synthesisers provide full automatic control of field level and all that is needed to provide an automated compliance test facility. Advanced features such as pre-scanning, display of EUT status against applied field level and full Windows compatibility are standard.

These synthesisers has been conceived with the practical user in mind. To make the best use of the immunity test facilities for both compliance testing and product investigations, several useful features have been developed. These include:

• Powerful EUT monitoring with real time display correlated to field strength and frequency.
• Sweep can be continuous or 'pause on fault' or 'stop on fault'. Additional EUT excitation output, either pulsed or continuous.
• Flexible single frequency search mode. Automatic ramping of field strength and fine control of frequency.
