IQRX™ is the gold-standard coherent receiver for the measurement of coherent modulation formats such as QPSK, 64QAM and ODFM.
Supports DP-QPSK, DP-16QAM and a variety of other PSK and QAM formats and custom formats
Narrow linewidth internal laser
Single ended RF outputs
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.
This product comes with a standard 1 year warranty. Optional 3 or 5 year extended warranties are also available.
