Description

The VSQ 3000 (VSQ 3002) is a radiation source for the frequency range from 800 MHz (30 MHz) to 3 GHz. It consists of a battery operated comb generator RSG 3000 and biconical broadband antennas DPA 4000A and/or DPA 3000, dependent on the wanted frequency range 30 MHz to 1 GHz and/or 800 MHz to 3 GHz. The comb generator is supplied by a high stable temperature compensated crystal oscillator (TCXO) and generates a frequency spectrum with a line spacing of 1 MHz, 5 MHz or 10 MHz. Combined with an antenna the generator represents a precise radiation source.

The VSQ 3000 / 3002 is suitable for various comparison measurements. It provides a radiation reference for comparing different test sites (e.g. OATS, anechoic chambers and GTEM cells) and set-ups. It may be used for the verification purpose as well as for quick checks of antennas and test set-ups. The VSQ 3000 / 3002 can be used to measure the attenuation of absorbing material or the shielding effectiveness of screening materials. A simple method, using the RSG 3000, allows the measurement of the attenuation of coaxial cables or attenuators without using a network analyzer.

All the components of the VSQ 3000 / 3002, the RSG 3000 and the antennas, can be used independently. The comb generator, being broadband, can give the same effect as a tracking generator when monitored by a test receiver or spectrum analyzer. With its high level stability, the generator is suitable for the fast calibration of measuring receivers’ level accuracy.

Also the antennas can be used separately for different EMC-measurements. They may be used as receiving antennas for emission measurements and restricted as transmitting antennas for susceptibility measurements.
