IFR 6844A 10 MHz to 24 GHz Scalar Analyzer with 24 GHz Spectrum Analyzer

The IFR 6844A is a dual-function system analyzer covering 10 MHz to 24 GHz, combining scalar analysis with spectrum analysis in a single integrated instrument. Built around a synthesized source, the 6844A delivers CW output, swept-source capability for scalar measurements, and tracking generator functionality for spectrum analysis. The receiver operates as a tuned input for high dynamic range scalar measurements, while an offset tracking source accommodates frequency translation device characterization.

This consolidation eliminates the need for separate test equipment, reducing bench space and setup complexity.
