PC Programmable Sources
ANS3 Series

  • 65 MHz to 5875 MHz
  • Frequency & Level Control
  • With Modulation/Trigger
  • Directly PC Programmable - RS232
  • 1KHz Steps
  • 7dBm Output Power
  • +/-1 ppm Stability
  • Low Cost & Compact Size
  • Wide Tuning Ranges
  • Low Phase Noise
  • Non-Volatile Memory

The ANS3 series of programmable, synthesised RF signal sources feature frequency and level control with modulation 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 serial port, each unit can be set to frequencies within ranges listed below and at levels up to 8dBm 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 a 9V d.c. wall mount power supply, operating software and special interface cable.
