Reference radiation source 30 MHz - 1 GHz
The VSQ 1000 is a radiation source for the frequency range from 30 MHz to 1 GHz. It consists of a battery operated comb generator RSG 1000 and biconical broadband antennas DPA 4000A. 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.
Comparison measurements
The VSQ 1000 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.
Attenuation measurement
The VSQ 1000 can be used to measure the attenuation of absorbing material or the shielding effectiveness of screening materials. A simple method, using the RSG 1000, allows the measurement of the attenuation of coaxial cables or attenuators without using a network analyzer.
Other applications
All the components of the VSQ 1000, the RSG 1000 and the antenna, 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. The antenna can be used as receiving antennas for emission measurements.
