The VSQ 2000 is an RF radiation source covering the frequency range of 1–18 GHz. It can be used for
checking the parameters of Open Area Test Sites (OATS), anechoic chambers or other alternative measuring
environments. The VSQ 2000 consists of a high?stability comb generator RSG 2000, and a broadband
horn antenna. The comb generator uses a temperature?stabilized quartz?oscillator (TCXO) and delivers
spectral lines with a 100 MHz spacing. It can be powered from either four rechargeable batteries NiMH
or an external power supply.
The condition of the batteries is monitored and with a LED indicated. The RSG 2000 will switch off
automatically, if the battery voltage falls below a preset limit.
Included in the VSQ 2000 standard package is a broadband horn antenna (1–18 GHz) with tripod.
The VSQ 2000 can be used for a multitude of measuring tasks in the EMC area. It allows reference
measurements to be made between OATS and anechoic chambers and other alternative measuring
environments, such as GTEM cells. The VSQ 2000 is also suitable for daily validation of antennas and
other measuring equipment.
