PC Programmable Sources
ANS2 Series

  • 45 MHz to 2500 MHz
  • Frequency & Level Control
  • Directly PC Programmable
  • +10 dBm Output Power
  • +/-1 ppm Stability
  • Low Cost & Compact Size
  • Wide Tuning Ranges
  • Low Phase Noise
  • Non-Volatile Memory
  • Buffered RF Output
  • Turn-key Operation

The ANS2 series of programmable, synthesised RF signal sources feature both frequency and level control and, with a standard office PC, provide a turn-key solution to the provision of variable frequency sources for both systems and test equipment applications. Directly connecting to the PC parallel port, each unit can be set to frequencies within a typical 1.5:1 range and at levels up to +10dBm via an easy to use control panel software and the non-volatile memory enables the selected settings to be retained in the stand alone unit. Each unit contains a +/-1ppm stability reference TCXO but can also be used with an external reference. The sources are supplied complete with an 18V d.c. wall mount power supply, operating software and special interface cable.
