8334 Programmable Profile Simulator

Check up to five results to perform an action.

A New streamline way to perform simulation testing!

Weinschel 8334 Series of Attenuation Profile Simulators provide multi-channel high-speed attenuation control with synchronous output update capability. The unit allows for programming of up to 128K (131072) attenuation data points per attenuator and sweeping through those data points at user-programmable intervals from 100 msec to 1 sec per point. The system provides for non-volatile storage of up to four data point tables which may be later recalled under user control. Status and control TTL signals are available for external monitoring and sweep control via a rear-panel DE9 connector.

The 8334 Series are multi-channel configurations housed in 19 inch enclosures and can be configured for up to 8 attenuation simulator channels and can be configured for front, rear or through (front to rear) RF signal routing.

  • Programmable attenuation update rates from 100 µsec per point to 1 sec per point in 100 µsec intervals
  • External TTL trigger (with programmable polarity) allows for synchronization with other external hardware
  • Various TTL status outputs (Running, Programmable Sync, and Interval Update) for monitoring a profile
  • Supplied with industry standard communication interfaces:
    - RS-232 (Serial)
    - Ethernet Control (10/100 BaseT)
    - USB 2.0
  • Rack Configurable: Rack ears are supplied.
  • Applications for the 8334 Series include:

    • Simulate path loss on each channel or mobility scenarios between a handset and multiple base
    • Create arbitrary, synchronous attenuation profiles withtiming skews of <10 nsec between channels to
      replicate precision fading and handover scenarios
    • Generate coherent, multi-channel pulsed RF outputs for a given attenuation level
