The velocity factor (VF) is a fundamental property of the RF cables in the system under test, which affects the speed at
which signals travel through the system. The velocity factor varies from cable to cable, but its value is always greater than
zero and less than or equal to one.
If the system under test contains multiple cables of different velocity factors, the velocity factor of the longest cable should
be chosen for the VF setting.
8.2.1.14 Test Point Label
The user-changeable Test Point Label appears at the top left-hand corner of the application window. This label will appear
in the test report when the associated test point is recorded. The default label is “Top of Rack”.

Config Lock (iQA only)
The “Config Lock” icon shows whether the configuration mode is accessible or not.
8.2.1.16 Button Bar
The button bar is the main user-instrument interface.
8.2.1.17 HPA Temperature
This temperature display area doubles as an alarm status indicator. As soon as an instrument alarm is triggered it will
show an alarm message in red text in place of the temperature display. Press on the alarm message and the alarm
screen will be displayed. The description of an alarm can be seen by pressing on the specific alarm indicator. The HPA
temperature alarm is activated at 70°C and a soft cut-out occurs at 75°C, until temperature is restored to below 70°C.
