- Refer to the hardware requirements listed in S11 1 Coupler System Hardware Requirements.
- Ensure all components are installed in the chassis before completing the following steps.
- If using the PXIe-5842, ensure the modules are properly interconnected, as described in Interconnecting the PXIe-5842.
Note The PXIe-5831 does not have dedicated RF
IN/OUT ports. Use the IF IN/OUT 1 port as RF IN and the IF IN/OUT 0 port as RF OUT when
using a PXIe-5831.
- Connect the RF OUT or IF IN/OUT 0 port of the out port of the coupler using SMA cable.
- Connect the coupled port to the RF IN or IF IN/OUT 1 port.
- Connect the input port of the coupler to the DUT for measurement or the calibration kit for calibration using SMA cables.
- If using the PXIe-5841, share the local oscillator (LO) signal by connecting the TX LO OUT port to the RX LO IN port of the VST using a MMPX-to-MMPX cable. If using the PXIe-5831 or PXIe-5842, no additional connection needs to be made as the LO is shared internally.
S11 1 Coupler System Hardware Requirements
In this hardware configuration, use one coupler on the port of the DUT to measure the reflection wave of the DUT.
