Rapid 4 ms sweeps over 401 points accelerate production throughput, while wide 1 Hz–10 MHz IF bandwidths and up to 98 dB power sweep accommodate both low-noise devices and high-power components.
Available in two- or four-port form factors, each unit ships fully tested, freshly calibrated and loaded with current firmware—providing immediate, automation-ready performance at a fraction of new-instrument cost.
