Power On Self Test
At power On, the VNA Master runs through a series of quick checks to ensure that the system is functioning properly.
From the System Menu, the System Self Test (Self Test) runs a series of tests that are related to the instrument itself. The Application Self Test (Application Self Test) runs a series of tests that are related to the current operating mode of the instrument.
If the VNA Master is within the specified operating range with a charged battery, and if the self test fails, contact your Anritsu Service Center (anritsu.com/contact-us).
To start a self test when the system is already powered up:
1. Press the Shift key and then the System (8) key.
2. Press the Self Test submenu key. The Self Test results are displayed.
3. Press Esc to continue.
