The T1204 DFIU is designed to allow the testing of 700 Series indicators and other Line Replacement Units. Interface cables and overlays that are available for specific units are listed below:

The PSD60-2R Fuel Quantity Test Set is an accurate, stable unit designed to test AC capacitance type fuel quantity measurement systems and their line replaceable components. The PSD60-2R, along with aircraft-specific interface units or cables, provides complete capability to test most aircraft with AC capacitance systems.

SI-1404 and its companion unit the ATC-1400A Transponder / DME Test Set provide simulation and measurement capability for ATCRBS, Mode S and Mode 4.

The RCTS-003B Radio Communications Test System is designed to test life support radios fielded by the US Military and other Defense operations around the world. A fully self-contained, transportable and semi-automated Radio Test System, the RCTS-003B replaces the popular RCTS-003. New hardware and software enhancements provide additional test capabilities for COSPAS/SARSAT and SATCOM on the PRC-112G. As an integrated test solution, the RCTS-003B provides full functional testing of all operational modes.

Aeroflex's 9101 Hand-Held Spectrum Analyzer is a low cost, full-featured spectrum analyzer. With a frequency range up to 4 GHz, the 9101 can test all modern wireless local oscillators, plus the harmonics and spurs that can mix and break through into the pass-band. Its complete coverage of carrier and IF stages give the performance needed when other analyzers run out of bandwidth.

The WiMAX measurement suite expands the capability of the Aeroflex 3030 Series PXI RF digitizers to perform WiMAX PHY (physical layer) OFDMA power, spectrum and modulation measurements in accordance with IEEE 802.16e

The 6103 AMR Air Interface Monitor and Emulator (AIME) has been designed to address the demanding test requirements posed by the introduction of AMR technology. It is a modular system which emulates an AMR capable GSM network and has been developed specifically for testing the Layer 1 and Layer 3 performance of GSM AMR capable terminals. The modular concept allows the user to configure the system to his particular requirements. For Research and Development applications, the 6103 AMR AIME is capable of the following functionality:

The SVA converts RF signals into digital IF or I&Q sampled data providing vector signal analysis of RF signals with functionality and performance required in the laboratory or the manufacturing test system.
