VSQ 1000

Reference Radiation Source 30 MHz - 1 GHz

VSQ 1000zoom
  • Radiation source up to 1 GHz
  • Comb generator 1 MHz to 1 GHz
  • Switch able spectrum with 1, 5 or 10 MHz
  • High stability for frequency and level
  • Changeable accumulator set
  • Earth free operation

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 4000. 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.
