The Marconi IFR Aeroflex 59999/169 is an autotester for precision RF measurements across 10 MHz to 40 GHz. It interfaces via a 2.92 mm female connector and delivers the directivity and port isolation required for return loss and VSWR characterization. Engineered for integration with scalar analyzers and detector modules, this instrument combines broad frequency coverage with controlled insertion loss and well-defined reflection coefficient accuracy across its operational range.
