Performance Tests (Agilent N7840A Software Package)

The Agilent N7840A software package verifies the electrical performance of your E8364B
PNA series microwave network analyzer. The software automatically configures your
analyzer to execute the performance tests. The N7840A software package is not included
with the analyzer; it must be ordered separately. The model numbers of the equipment
used are specified under
There are nine tests in the software package:
• Source Power Linearity Test
• Source Maximum Power Output Test
•

Source Power Accuracy Test

• Frequency Accuracy Test
• Trace Noise Test
• Receiver Compression Test
• Noise Floor Test
• Calibration Coefficient Test
• System Crosstalk Test
• Dynamic Accuracy Test
IMPORTANT The descriptions of these tests are provided here as a convenience only. These
tests are subject to change at any time. As a result of such change, the
descriptions provided here may no longer be accurate. Refer to the N7840A
product itself for the latest, most accurate descriptions of the tests.
Source Power Accuracy Test
Function of the Test: To confirm the accuracy of the source output power of your network
analyzer over its full frequency range.
Specification Tested: Test Port Output–Power Level Accuracy
Equipment Used: A power meter, power sensors, and adapters.
Description of the Test:
1. The analyzer's output power level is set to 0 dBm.
2. A power sensor is connected to Port 1.
3. The output power is measured at hundreds of CW frequencies across the analyzer's
frequency range and the values compared to the setting of 0 dBm.
If the Analyzer Fails this Test:
• Perform the "Source Calibration Adjustment" on page 3-47
• If the analyzer still fails this test, replace the source assembly and repeat this test.
