Spectrum Master™ Handheld Spectrum Analyzer User Guide : System Operations : Self Test
 
Self Test
At power on, the Spectrum Master runs through a series of quick checks to ensure that the system is functioning properly. The System self test runs a series of tests that are related to the instrument hardware. The Application self test runs a series of tests related to the instrument hardware that is used in the current operating mode.
If the Spectrum Master is within the specified operating range with a charged battery and the self test fails, contact your Anritsu Service Center at anritsu.com/contact-us.
To initiate a self test when the system is already powered up:
1. Press the Shift key, followed by the System (8) key.
2. Press the Self Test submenu key. The Self Test results are displayed.
3. Press Esc to close the Self Test results dialog.
