3515 Military Radio Communications Test Set

The Aeroflex 3515 was developed for military use and offers the latest in portability, battery life and performance. The Aeroflex 3515 combines many of the features of a benchtop radio test set with the features of a Frequency Domain Reflectomer (FDR) into a lightweight, rugged and portable platform. The 3515 is perfect for testing AM and FM radio transceivers, whether on a bench, installed in a vehicle, or in some remote location.

Version 2.4.1 Firmware Upgrade is Now Available!

New return loss and one port cable loss measurements enable comprehensive testing of antennas and cables

The 3515 Radio Test Set now allows the user to measure and graphically display return loss and cable loss. The return loss of an antenna or other device is displayed in graphical form as return loss (in dB) versus frequency. The loss of a cable is similarly displayed graphically as loss versus frequency. These two measurements are in addition to the VSWR and distance to fault (DTF) measurements that were already present on the 3515. With these four measurements, a complete analysis can be done on the cabling and antenna of a radio system.

Drive-by testing isolates radio installation failures

Design for portable operation, the 3515 is ideal for performing radio installation testing. By utilizing over the air testing techniques, a radio installed in a vehicle can be tested, without making a direct connection. A handset is included to help make voice quality measurements of the transmitter and receiver. Additionally, the 3515 provides a standard H-250 adaptor to use with the standard H-250 SINCGARS handsets.

New DCS generator and Audio Frequency Counter (AF Counter) expand the functionality of radio test in the 3515.

A DCS generator and AF Counter are the latest additions to the radio testing capabilities of the 3515. The DCS generator enables the testing of radios that require the DCS (Digital-Coded Squelch) to un-squelch the audio. The new Audio Frequency counter measures the frequency of audio tones, whether from the audio in port, or the demodulated audio.

Benchtop type tests allow the 3515 to go further than simple go/no go testing

With the 3515 as your test tool, you have the capability to go past simple go/no go testing. The transmitter and receiver test screens include meters to measure transmitter parameters such as power, frequency and modulation. The receiver test screen includes meters to measure receiver sensitivity (SINAD) and audio distortion. The 3515 even includes two audio generators that can be used either at baseband or to modulate the transmitter. All of these features combine to make the 3515 a complete radio test set for FM and AM radio transceivers.
