Description

Model 50P-2055 is a USB controlled solid-state programmable attenuator operating 20-3000MHz.  It has a maximum attenuation setting of 95.5 dB with 0.5 dB step size.  It is 50 Ohm impedance with SMA female RF connectors.  This attenuator is rated for +27dBm RF input power.

Shipped with USB Attenuator:

  • JFW Test Software (on USB thumb drive)
  • JFW Test Software Manual (on USB thumb drive)
  • USB Cable (USB A male to USB B male)

USB Test software Features:

  • Test software manual available for download.
  • Auto-discovery of any JFW USB attenuators connected to the computer.
  • Control attenuator(s) using a slider bar, increment buttons, or manually entering the attenuation value.
  • Set persistent device names for better organization of complex test scenarios.
  • Create test scripts that can control many attenuators.
  • Fade and Handover commands can be executed in Sequential or Synchronous mode.
  • Saving and Loading of scripts in JSON format.
  • Requires Microsoft Windows Vista or greater.
  • Requires Dot Net Framework 4.0 or greater.

Python Library Available
If you would prefer to control the USB attenuators using Python instead of our standard Windows based test program, JFW does offer a Python library (jfwusb.py).  Email our engineering department for the Python library and examples.

Python Library Features:

  • Auto-discovery of any JFW USB devices connected to the computer.
  • Set persistent device names for each attenuator.
  • Set/read attenuator by its device number.
  • Set/read attenuator by its serial number.
  • Set/read attenuator by its user defined name.
  • Set all attenuators to the same dB value, min dB value, or max dB value.
