measurement from 9 kHz to 8.5 GHz with a class-leading 140 dB
dynamic range and trace noise below 0.004 dB, ensuring clean
characterization of filters, amplifiers and high-speed
interconnects.
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
