High Tech Testing That's Easy to Use

Building advanced functionality into a test instrument means little if it's too complex to use efficiently. That's why we've focused on ensuring the IFR 2975's advanced functions are easily harnessed.

Exclusive control features include a standard communication service monitor look and feel with push-key entry and soft-key functions for routine daily work. But added to this conventional operation is the power of today's technology including:

  • Ethernet for remote control flexibility
  • Internal web server for accessing files, status updates and remote display operation
  • E-Manual support allows you to upload test and alignment procedure for display directly on the IFR 2975
  • PS2 keyboard and mouse operation
  • Full GPIB and RS-232 interface with Remote Command Language
  • On-board 20 GB hard drive to support future enhancements

Exclusive Spectrum Analyzer Features Include "Quick Tune" Feature

Tuning the spectrum analyzer is as simple as a double click on the mouse. With Aeroflex's exclusive "Quick Tune" spectrum analyzer, the IFR 2975 allows you to double click a signal on the spectrum analyzer screen and the analyzer will automatically change center frequency to the selected frequency.

Supports Network Connectivity

Another key advancement is the use of modern network and connectivity technology. The IFR 2975 employs ethernet as one of its communication ports, thus allowing remote operation and data collection.

You can also redirect display and keypad operations and software upgrades can be installed quickly over the internet, saving you valuable time and virtually eliminating instrument downtime.

Man-Machine Interface

The high-resolution color display and alphanumeric keypad with multi-function soft keys provide a user-friendly interface. The menu structure has been enhanced to make complex test routines simple and straightforward. A 20 GB internal hard drive and 3.5 in. floppy drive simplify program installation and maximize flexibility in storage and recall of setup information, frequency lists and test data.


At 15 kg (33 lbs.), the IFR 2975 is perfect for the field technician with a lot of ground to cover. Plus, its rugged design makes it an ideal solution for the rigors of the field.
