8712ES

The Keysight (Agilent) 8712ES is an RF economy vector network analyzer covering a frequency range of 300 kHz to 1.3 GHz. Featuring a built-in S-parameter test set with full two-port vector-error correction, it provides fast, accurate characterization of active and passive RF components like filters, amplifiers, antennas, and cables. The 8712ES offers standard features such as a 60-dB source step attenuator, 3 to 1601 sweep points, multiple IF bandwidth choices down to 15 Hz, and a 3.5-inch floppy drive, making it a highly productive and cost-effective test solution for both production and R&D.
