HP 11759C RF Channel Simulator, 50 MHz to 2700 MHz![]()
|
The HP 11759C consists of the application software and the RF processing hardware. To complete the RF multipath simulation system, two user-supplied components are necessary; a PC acting as a user-interface and a synthesized LO used to determine the RF operating frequency and to supply a 10 MHz clock signal. The HP 11759C contains two independent 40 MHz to 2700 MHz RF channels of three paths each. Each path can be Doppler shifted or Rayleigh or L og-normal faded, delayed, and attenuated relative to the others. In addition, under Rayleigh fading conditions, the correlation factor for path pairs in the two channels is adjustable from 0 to 1 in 0.1 steps.
For test applications requiring more paths per channel (e.g., GSM or DCS1800), the HP 11759C Option 001 configures the HP 11759C as one channel of six paths. By pairing two HP 11759C Option 001 units and controlling them from a single PC, the full 12-path testing requirements of the GSM and DCS1800 systems can easily be accomplished. And, to make it even easier, the 12- and 6-path propagation models are pre-stored in the PC's memory for easy recall and setup. Simple-to-use onscreen menus guide the user through the task of creating complex RF multipath signals for testing a mobile or base station radio. These same menus are accessed remotely by installing an HP-IB interface card in thePC.
