Application Self Test Results Window — VNA
Application Self Test (Vector Network Analyzer mode only)
To run the application self test, press Shift and System (8) and then Application Self Test from
within the desired mode. When you are in Vector Network Analyzer mode, you will see the
results window that is shown in Figure C-2 (note that your instrument display may differ
from this image), which summarizes the status of several key functions that are specific to
this application.
If the Overall Status shows Failed, then one or more elements of the Application Self Test
have failed. This self test consists of 4 subtests:
Power Supply Test: Lists any power supply voltages that are not meeting tolerance
specification
VCO Calibration: Lists any frequency range over which the VCO calibration is failing
Frequency Sweep: Lists any frequency range over which errors in the sweep are occurring
EEPROM: Indicates whether reading or writing (or both) to the EPPROM has failed
