PNA and PNA-X Receiver Compression Note

Systems configured with PNA or PNA-X series Network Analyzers will show compression at the beginning
of the frequency range when power level is increased. Typically, this will occur when power level is
increased above 5dBm. This occurs because the PNA and PNA-X analyzers use couplers at the test port
and the multiport extension test set has a directional bridge at the test port. The PNA and PNA-X receivers
are calibrated at the factory, and due to the higher coupling factor, the coupler at low frequency, the
receiver gain is set high to compensate. The multiport test set directional bridge has a lower coupling
factor at low frequencies, which results in compression when power level of the PNA/PNA-X is increased.
We recommend you increase the receiver attenuation in the PNA and PNAX to reduce this receiver
compression issue.
Network Analyzer Requirements
For multiport operation (N-port error correction and measurement capability) all "A" model network
analyzers require Option 551 and all "B" model analyzers require Software Application S93551B. For "B"
models in which the system is configured with more than eight test ports, it is recommended to use PLTS
Software N1930B to manage/control any advanced network analyzer measurement applications and their
large data files.
Table 2 provides a listing of other network analyzer option requirements. The analyzer's frequency range
must be equal to or exceed that of the test set so that the measurement system covers the full frequency
range of the test set. The test set files indicated in Table 2 must be installed into this network analyzer file
directory location: C:\Program Files (x86)\Agilent\Network Analyzer\TestSets.
For the "B" model PNA-X: C:\Program Files (x86)\Agilent\Keysight\Network Analyzer\Keysight\TestSets.
