Stevenage, England — Aeroflex Incorporated has added differential I/Q output to its 3410 series signal generator family for improved testing of RF integrated circuits (RFICs).

Today, most RF communications ICs with I/Q modulators use differential input ports to separate the I and Q signals and eliminate the effects of common mode interference. The separation of the chip inputs cancels out noise effects and improves the quality of the mobile phone or other end-user product where the RFIC is used.

The 3410 series is a family of portable, lightweight signal generators covering a wide range of carrier frequencies up to 4 GHz. High quality analog and vector modulation capabilities make these signal generators suitable for research, development and manufacturing applications.

The 3410 series Differential I/Q Output Option 009 can be ordered new with the product or sent to the factory for upgrade on existing 3410 series products. It requires the installation of the arbitrary waveform generator (Option 005) and is not available with Pulse Modulation (Option 006).
