High Power Measurements with the U3024AH10
The Test Set and the PNA-X can be configured to measure high power devices. This ability is
useful if the required power for the DUT is greater than what the analyzer can provide, or if the
maximum output power from the amplifier under test exceeds the safe input limits for the
analyzer. This section describes how to set up the PNA-X and Test Set with external couplers,
attenuators, isolators and booster amplifiers to perform high power measurements.
•
The external couplers are used to provide reference power to the PNA-X (REF 1 and REF 2)
for accurate measurements.
•
The attenuators are used to protect the PNA-X receivers.
•
The isolators are used to protect the internal Test Set switches and the PNA-X source.
•
The booster amplifiers are used to provide added gain.
When using high power configurations an attenuator must be placed in the
receiver path, and the couplers and isolators must be installed in the source
path, or damage to the PNA-X or the U3024AH10 Test Set will occur. Refer to
“Frequency Range and Maximum Power Levels” on page 8
The internal firmware of the Keysight PNA-X Series Network Analyzer
has not been modified for this Test Set option. Power levels may differ
from those indicated on the PNA-X when the Test Set is connected.
Refer to the configuration diagrams for external component connections and/or
operating constraints when utilizing the high power capability. External
components are not supplied with the high power Test Set. See
The high power Test Set is equipped with receiver access ports. The jumpers
can be removed to insert attenuators that will reduce the RF power to the PNA-
X A,B and R channel receivers. Recommended power levels to the PNA-X
receiver ports is –15 dBm. Refer to your PNA-X specifications to optimize power
levels to the receiver ports.
Prior to powering-up the booster amplifier it is highly recommended that the
user verify the RF power levels seen by the various elements of the Test Setup.
Both the PNA-X and Test Set power levels must be taken into consideration. At
high power levels, a mistake could damage the instruments. Accordingly, the
following key values are given in
