The DPA 4000A is c***tructed so that it can be converted easily to a Reference Radiation Source in combination with the Reference Spectrum Generator RSG 1000 or RSG provides reference measurements between open area test sites and alternative facilities as e.g. anechoic chambers and GTEM- may be used for calibration of these alternative facilities as well as for quick checks of antennas and test set-ups. Further this combination can be used to measure the attenuation of absorbing material or the shielding effectiveness of screening materials.*) with VSQ 1000/3002Antenna type:   biconical dipole antennaPolarisation:   linearFrequency range:   200 MHz to 1000 MHzAntenna factor, typ.:   20 dB/m to 32 dB/mIsotropic gain, typ.:   -3.5 dB to +1.5 dB VSWR, typ.:   ≤ 2.0 (350 MHz to 1000 MHz)Symmetry, typ.:   ≤ 0.2 dBCross-polar resp***e:   > 20 dBOutput impedance:   50 Ω, nominalConnector:   N femaleMax. power (cw):   5 WSize (L x W x H):   185 mm x 400 mm x 155 mmSupport length:   155 mmWeight:   690 gRecommended tripods:   BTP 6010 + BAA 6001 + CHA 9425A or     BTP 6020A + BAA 6001 *) with VSQ 1000/3002Part number  Description234350  DPA 4000A   Biconical antenna  200 MHz - 1 GHz 97-244570   Ant Cert-TC       Traceable calibration (ISO17025), order only with the antenna, free   space calibration (horizontal), other calibrati*** on request234304   BTP 6010        Tripod for DPA 3000/ 4000 included in  VSQ 1000/ 300x244579   BAA 6001       Dipol antenna tube for DPA 3000/ 4000, included in VSQ 300x348-801   CHA 9425A  Enables antennas with 22mm tube to ? t on to masts but bolts onto the top of the boom.
