Comb Generator Emitter CGE04 – 100 MHz to18 GHz

The CGE04 is a broadband reference comb source producing signals within the 100 MHz to 18 GHz frequency range. The CGE04 updates and replaces the older CGE01 comb source.

The CGE04 is designed for the purpose of performing checks on fully- or semi-anechoic chambers, and other similar test environments. It is equipped with a precision SMA output connector to which an antenna (optional) can be fitted for generating radiating E-fields. The CGE04 is housed in a metal enclosure so that it can be mounted in direct electrical contact with a ground plane, as may be required by some tests.

The CGE04 is compact and can be run from a 9 – 18 VDC PSU01 power adapter. To minimise cable effects when characterising an electromagnetic environment, it can also be run independently using a PPU01 NiMH battery pack.

The comb signal allows both reference and noise floor signal levels to be viewed simultaneously, aiding dynamic range measurements.

KEY FEATURES

• 100 MHz to 18 GHz output – Applications across a broad spectrum

• Stable output – Repeatable measurements

• Selectable comb output frequency – Flexibility across a range of applications

• Compact and portable – 56 x 17.5 x 72 mm

• PPU01 battery or external power supply – No power cable effects when using the PPU01 – Continuous operation using the external 18 VDC power adapter

APPLICATIONS
