3 GHz Transmission / Reflection Network Analyzer VNA Agilent 8753ET

The pre-owned Agilent 8753ET couples a synthesized 300 kHz-to-3 GHz source with an integrated T/R test set, delivering forward-direction S-parameter magnitude and phase in one compact enclosure. With up to 110 dB dynamic range, the analyzer exposes filter ripple, cable loss, and antenna mismatch without external boosters, while four display channels let engineers monitor multiple traces at a glance. Option 006 lifts the ceiling to 6 GHz, and add-on time-domain or harmonics firmware broadens diagnostic reach.

Buying refurbished slashes cap-ex and lead-time; units ship ISO-17025-calibrated and firmware-verified, preserving Agilent reliability and SCPI/LAN code compatibility.
