Rohde and Schwarz ZNH-K45 - Vector Voltmeter Option for ZNH Vector Network Analyzers

The R&S ZNH-K29 option enables precise pulse and peak power measurements using the ZNH together with a Rohde & Schwarz wideband power sensor. Field applications benefit from this compact, powerful combination. The R&S ZNH-K45 vector voltmeter option displays the magnitude and phase of a DUT at a fixed frequency. The R&S ZNH can therefore replace a conventional vector voltmeter for many applications. The required signal source and bridge are already available in the R&S ZNH.

The setup is extremely simple, which makes the R&S ZNH-K45 ideal for field use. The results of relative measurements from a reference DUT can be stored at the push of a button. Comparison measurements, e.g. between various RF cables and a reference cable (golden device), can be quickly and easily performed.

Typical applications are:

• Adjustment of electrical cable length
• Installation, maintenance, and troubleshooting of phase-controlled antennas, for instance localize antennas used in instrument landing systems (ILS) for air traffic control
• Calibration of monopulse radars
