PXIe-5673E Calibration Procedure
5.
Repeat steps 3 through 4 for the following frequency ranges in 5 MHz increments,
including endpoints:
•
PXIe-5650: 85 MHz to 1.3 GHz
•
PXIe-5651: 85 MHz to 3.3 GHz
•
PXIe-5652: 85 MHz to 6.6 GHz
Store the resulting measurements as
direct [i]
(dB).
6.
Disconnect the power sensor from the PXIe-5650/5651/5652 RF OUT front panel
connector.
7.
Connect the input port of the power splitter to the PXIe-5650/5651/5652 RF OUT front
panel connector through the SMA(m)-to-SMA(m) adapter.
Note
If you use a cable, it should be as short as possible. The cable should always
be used with the splitter for subsequent verification procedures in this document that
require a splitter.
8.
Connect one available output port of the power splitter to the power sensor without a cable,
if possible. Label this port A.
Note
Remember the port to which the power sensor is connected. The power sensor
must be connected to the same port for subsequent procedures in this document.
9.
Connect the other output port of the power splitter to a 6 dB attenuator. Label this port B.
10. Connect the other port of the 6 dB attenuator to the spectrum analyzer RF INPUT front
panel connector through the SMA(m)-to-SMA(m) cable as shown in Figure 1.
11. Configure the reference level of the spectrum analyzer to -30 dBm. The spectrum analyzer
is used only for termination.
