• Narrow linewidth internal laser
• Single ended RF outputs

Features

High-performance, low-noise coherent receiver

IQRX is designed and built using the highest-performing discrete fiber optic components to provide superior fidelity measurement of coherently modulated signals. To minimize noise, IQRX does not use a transimpedance amplifier (TIA), a component often found in commercially available ICRs.

Dual polarization measurement

IQRX houses polarization selective hardware to characterize polarization multiplexed signals. LO input, signal output and internal laser outputs all use polarization maintaining (PM) fiber for the highest versatility.

Four single-ended outputs

Designed to be used with any real-time oscilloscopes with sufficient bandwidth and sampling rate, the single-ended outputs make it convenient to pair with the four input channels of most oscilloscopes. In high-bandwidth oscilloscope configurations where there are only two channels per unit, IQRX’s slim profile and wide footprint enable it to be placed between multiple oscilloscope units.

Built-in narrow linewidth tunable laser

IQRX comes with a built-in narrow 25 KHz instantaneous linewidth laser, making it perfect for coherent modulation formats that require high phase stability.

19 inch rack mountable

IQRX can be paired with the rack mount brackets for easy mounting in any 19 inch rack.
