It can be used for checking the parameters of Open Area Test Sites (OATS), anechoic chambers or other alternative measur?ing 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.Frequency range: 1–18 GHzComb spacing: 100 MHzFrequency stability (TCXO, 100 MHz): < 1 ppm (?20° – +70°C)Aging: < 1 ppm/yearFequenzy correction (internal): < 5 ppmSignal stability: < 0.3 dB (20°C const.) < 0.5 dB (+5° – +40°C)Output of generator (RSG 2000): > 68 dBμV at 18 GHz, 50 ΩField strength: > 65 dBμV/m at 1 m > 55 dBμV/m at 3 mTemperature range for working: +5° to +40°CBattery power: 4 × 1.2 V NiMH, 3500 mAh, interchanged Condition indicated by LED Working time 4 hSeparate power unit: 100–240 VAC, 5 VDC, 2 AAntenna: Double?ridged waveguide horn, 1–18 GHzTripod: 800–1500 mmDimension of the generator (RSG 2000): 105 × 90 × 130 mmAttenuation measurementThe VSQ 2000 can be used to measure the attenuation of absorbing material or the shielding effective?ness of screening materials. A simple method, using the VSQ 2000, allows the measurement of the attenuation of coaxial cables or attenuators without using a network analyzer.Simulated tracking generatorBoth components of the VSQ 2000, the RSG 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 accuracyPart number Description 244500 VSQ 2000 Reference radiation source 1–18 GHz246600 RSG 2000 Reference generator 1–18 GHz97?246600 RSG 2000?TC Traceable calibration (ISO 17025) of RSG 2000, order only with the device
