Rohde & Schwarz URV5-Z4

This Insertion Unit is used for uninterrupted level measurements between source
and load and for terminated power measurements.

Due to their wide frequency range they are ideal especially for the measurement of EMC test levels as well as many general purpose applications.

This unit is made up of a short, coaxial line between the two RF connectors, in the middle of which the voltage is tapped: directly with URV5-Z2, and via a capacitive 20dB divider with URV5-Z4.

This unit is calibrated so that the power incident upon them is indicated.

With a poorly matched load, precise absolute value measurements are not
possible, but relative measurements can be performed and system applications implemented in which subsequent calibration of the complete test setup takes place.
