F-Intermod calculates RF and optical intermodulation products.  Up to 1000 transmit and 1000 receive frequencies can be entered with a frequency range from 0 Hz to 999,999.99999 THz and for optical 0 to 999,999.99999 nm.  Unlimited calculated intermodulation frequencies output with order of 2 and higher.

A must have for radio engineers, fiber optic DWDM network planners, and CATV engineers!

Features

• Input frequencies from 0 Hz to 999,999.99999 THz, Optical 0 to 999,999.99999 nm
• Input up to 10000 channels (transmit and receive frequencies)
• Calculates Intermod Order from 2 to 31
• Input unique bandwidth for every channel
• Harmonics (if known) can be entered as separate entries
• Input Full Duplex, Half Duplex or Simplex channels
• Export to Microsoft Excel and other spreadsheet readable .csv file
• Input alphanumeric channel names and show channel names in output
• Very fast algorithm, computes output much faster than other programs
• Store input values in file for future calculation
• Unlimited Intermod output
• Channel database integrated into F-Intermod. Store unique channel information, such as location, contact information, comments, etc. for each individual channel
• Formula output format allows for easy viewing of large channel outputs
• Output window filter - specify a frequency range to be used as an output window or test frequency
• Sort using any output column
• Can be installed on Windows servers and network.
• Calculate and output intermod products only due to new planned frequencies for an existing radio site.  This allows engineers to see the intermod impact of new frequency/channel additions that are planned for an existing radio site.
• Automatically calculates input receive frequency feature.
• Option to list all intermod frequencies without receiver bandwidth filtering.
   

New Feature for release 4.2:
Now calculate fiber optic DWDM four wave mixing (FWM) products for systems with up to 1000 channels!

System Requirements

Windows 98/ME/XP/2000/Vista
800x600 Monitor or Better
128MB RAM Minimum
10 MB Hard Drive Space

Client / Server Network Installation

The single user license version can be installed on a network server computer but each client computer will need to be licensed.  We also offer a client / server version of this product that can be installed on any Microsoft Windows client computer and server connect in a TCP/IP LAN network.  Price for each user license is $95.  The number of user licenses purchased will be able to access F-Intermod client simultaneously without needing to enter a key.  Client F-Intermod software can be installed on any number of computers.
