1. A 2-way high power source configuration can be configured for transmission and reverse
transmission measurements. Refer to Figure 58 on page 78 .
2. The even ports SRC OUT connection is similar to the odd ports, although located on the right side of
the front panel. Refer to
Figure 45 on page 61
.
3. The Port 2 SRC OUT connection is similar to the odd ports, although located on the right side of the
front panel. Refer to
Figure 46 on page 61 .
20 Watts Port 2 See Figure 46 on page 61
Port 3 to 12 SRC OUT 20 Watts Port 3 to 12 See Figure 47 on page 62
Additional attenuation may be required between the coupler and the power
meter to protect the power meter from damage.
1. Connect the Test Set to the PNA-X. See "14-Port System Setup" on page 15 and Figure 42 on
page 56 .
2. Determine the Test Set and PNA-X ports that will be configured for high power measurements.
Each port can be configured separately. Refer to Figure 45 and Figure 46 on page 61 , as well as
the block diagrams beginning on page 76 .
3. Remove the Test Set front panel jumpers for the selected high power configuration.
4. Connect the Coupler Main to the Amplifier Output.
5. Connect the Amplifier Input to the Odd Port SRC OUT or the port desired to be the source. The
RF source power comes from the PNA-X SRC OUT connector. Do not connect the external
Coupler Output or Coupler ARM at this time. Refer to Table 17 below, Figure 46 on page 61 ,
and Figure 47 on page 62 .
6. Turn on the PNA-X and the U3024AH10 Test Set.
7. Select Multiport mode. Refer to "Controlling the System with the Network Analyzer " on page 30 .
8. Select trace S11 if you are using Port 1 or Odd Ports SRC OUT. If you are using another port as
the source port, set Sxx to the port desired. For example, S33 would be Port 3.
9. Set the Power Level to -20 [dBm]. Save this state as User Preset to avoid an over-power
condition by the factory preset power level (-5 [dBm].
10. Turn on the booster Amplifier.
11. Using a power meter, measure the Coupler Output power.
