RF Emissions (Cell/Chamber)


LC300/2

Typical arrangement for emissions measurement in LC300/2

Test CellEquipment required:

A   LC300/2 Test cell
B   SA1002 EMC analyser
C   Software for your PC
Note:
For 3GHz system, change EMC analyser to SA3000.
The LC300 accepts products up to 30 x 30 x 30cm.
Filters for I/O feeds to the EUT can be fitted to suit customer requirements (eg, USB, Ethernet, Power, RS232, RF feeds, etc…)

 


LC600

Typical arrangement for emissions measurement in LC600

Equipment required:

LC600 Test cell
SA1002 EMC analyser
Software for your PC
Note:
For 3GHz system, change EMC analyser to SA3000
The LC600 accepts products up to 60 x 60 x 60cm.
Filters for I/O feeds to the EUT can be fitted to suit customer requirements (eg, USB, Ethernet, Power, RS232, RF feeds, etc…)


 

Chamber emissions measurement system

Equipment required:

A   RF200 Antenna + stand
B   SA1002 EMC analyser
C   SA1020 pre-amplifier
D   ERS Reference source
E   Chamber
F   Software for your PC
Note:
Contact Laplace for discussions regarding the chamber.
For 3GHz system, add RF230 antenna and change EMC analyser to SA3000

RF Emissions Chamber

Practical notes:
Ambient noise will be essentially eliminated. However, chamber characteristics may introduce uncertainties which can be corrected by use of the ERS. Diagram shows SAC (Semi Anechoic Chamber) with reflective floor to emulate OATS. FAC (Fully Anechoic Chamber) has RF absorber on the floor. This avoids the requirement for height scanning of the antenna.
