Main Unit only. No software or interconnect cables available.

   The Agilent/HP 11759C RF channel simulator has all the features and performance characteristics that make it ideally suited for testing digital cellular radios under RF multipath conditions.  Whether the radio is designed for operation with the CDMA (Option H30), GSM, NADC, DCS1800 or PDC cellular systems, it is easy to simulate the fast and slow fading, time dispersion and Dopplers experienced in the mobile radio environment.  The Agilent/HP 11759C is also suitable for testing many other analog and digital wireless communications systems with RF bandwidths to 6.0 MHz under multipath fading conditions. The 11759C consists of the applications 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.


  • Simulates realistic signal propagation for CDMA, NADC (TDMA or E-TDMA), GSM, PDC, DCS1800, PHS, and more
  • Rayleigh, Rice, or Long-normal fading
  • RF bandwidth > 6.0 MHz
  • Doppler to 425 Hz
  • Delay intervals to 186 µ in 1 ns steps
  • PC controlled

Two Multipath Channels Provide Test Flexibility

   The Agilent/HP 11759C contains two independent 40 MHz to 2700 MHz RF channels of three paths each.  Each path can be Doppler-shifted, Rayleigh or Log-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. With an external power divider and/or power combiner, and two separate channels available, it is easy to configure the HP 11759C(s) for single-channel 6 (or 12) path tests, co-channel interferer tests, adjacent and alternate channel tests, and space and/or frequency diversity tests.  This flexibility is particularly important during the radio R&D phase and also important for manufacturing test and type acceptance testing.

Easy to Use Manually or Remotely

Simple-to-use onscreen menus guide the user through the task of creating complex RF mulitpath signals for testing a mobile or base station radio.  These same menus are accessed remotely by installing a HP-IB interface card in the PC.
