Span Control State - DEVA Broadcast DB7002 Maintenance And Operation Instruction Manual

Span control state:

[SB1], [SB2] and [Arrow] buttons control the Span of the data plot. Depending on the Span
control state the Soft buttons have different usage.
– [SB1] cycles through available span values for X axis of the data plot. The
possible values vary between 26, 30, 34 and 38 channels. Note that changing X span may also
change the center frequency in order to keep data plot in bounds. When a key is pressed next span
value will be selected and displayed on the screen.
– [SB2] cycles through available span values for Y axis of the data plot. The
possible values are 20, 30, 40, 50 and 60 dBμV. Note that in order to keep the data plot in bounds
changing Y span may also change the Y reference. When the button is pressed new value will be
selected and displayed on the screen.
