Noise Receiver Compression Performance Test
This test applies to the following models:
This test is to measure the worst case compression of the RF components
of the noise receiver. The noise receiver compression is, as with all
compression, a measurement of the non-linearity of the noise receiver
at high input powers. This test has been defined to measure the compression,
or linearity, of the noise receiver at a specified input-power level relative
to a lower power level that is within the receiver’s linear range. For
this test, compression is defined as the difference between the change
in power input to the receiver and the change in power measured by the
receiver.
The PNA source will provide the power at the receiver. A pad can be
used to improve the match of the source over power. This may be required
because the noise receiver is sensitive to match changes which could happen
with input power changes. The source output power is measured and adjusted
as necessary to ensure that the appropriate test power level is injected
into the port. The source is then connected to the noise receiver port.
At each frequency the source is set to output the required power, and
a measurement is taken with the noise receiver. The power delivered
to the port is measured with the port receiver (can be frequency swept
measurement). The source power is next offset by the specified power step
(delta power) and a measurement is again taken with each receiver.

Connection Setups
|
|
Due to the complexity of the PNA family of analyzers, the following notes apply to illustrations in the PNA Help:
- Only a single representative PNA model will be shown. Therefore, port locations may differ in older PNA models than what is shown in the illustration. Refer to the port labels on the UUT.
- Some illustrations may differ than those in TME.
- If the test procedure applies to multiple ports, illustrations may show the setup on only one test port.
- Setups for some option configurations may not appear in the Help.

Flexible power sensor channel assignment
PNA models running the Factory Recommend Variant will use flexible power sensor channel assignment that will identify the channel that a power sensor is connected to using the ability of "smart" sensors such as the N848xA and U848xA series to report their full model and serial number. Therefore it is important to keep the power sensor on the channel where it was calibrated throughout the test procedures.
For more information about test plan variants, refer to the Test Plan Variants topic.
