Two RF measuring cables are needed for this purpose. Connect the first RFmeasuring cable to the probe output (Figure 94) and the SMA coupling (Figure 95) and the secondRF measuring cable to the SMA coupling (Figure 96) and the "RF in" connector on the Z-axis tower(Figure 97).Figure 94: Connecting the RF measuring cable to thenear-field probeFigure 95: Connecting the RF measuring cable to theSMA couplingFigure 96: SMA-SMA RA cable connected to the SMAcouplingFigure 97: SMA-SMA RA cable on the "RF in" connectoron the Z-axis towerConnecting a Near-Field Probe With a Pre-Amplifier18.1.2Note: The selection of the correct pre-amplifier depends on the measurement task and the near-field probe used. Please contact us should you have any queries (chapter 24).Connect the pre-amplifier's SMA output to the "RF in" input on the scanner's Z-axis tower(Figure 99).
