U3022AH10 High Power Measurements
Measuring Booster Amplifier Gain
1. Connect the Test Set to the PNA-X. See “System Setup N5242A PNA-X” on page 2 2 and Figure 50
on page 6 2 .
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 3 3 , Figure 4 7 , and Figure 4 8 , as well as the
block diagrams shown in Figure 55 and Figure 56 .
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 1 7 , Figure 4 7 , and Figure 4 8 .
6. Turn On the PNA-X and U3022AH10 Test Set.
7. Select multiport mode. Refer to “Controlling the System with N5242A /B ” on page 31 .
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. 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. Measure the Coupler Output power, using a power meter.
Additional attenuation may required between the coupler and the power meter
to protect the power meter from damage.

1. A 2-Way high power source configuration can be configured for transmission and reverse
transmission measurements. Refer to
Figure 56 on page 73 .
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 4 7 on page 6 1 .
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
