Connect the first RF measuring cable tothe probe output (Figure 94) and the SMA coupling (Figure 95) and the second RF measuringcable 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 towerImportant: Check that the connected near-field probe moves smoothly in the Z-direction. Thisensures that the movement is stopped correctly if a collision occurs. Carefully pull the near-fieldprobe up by hand and check its smooth motion for this purpose.Connecting a Near-Field Probe with a Preamplifier18.1.2Note: The selection of the correct preamplifier depends on the measurement task and thenear-field probe used. Please contact Langer EMV-Technik GmbH should you have any queries(Chapter 25).Connect the preamplifier's SMA output to the input marked RF in on the Z-axis tower (Figure 99).
