frequency is accepted as the new reception frequency.

To measure certain level minimums or maximums, you can move a

cursor on the level curve using the and buttons. The

frequency and the measured value are indicated in the top line of the screen. The measuring range is displayed on the ordinate in dBµV on the left side of the screen. The level measurement range is set automatically.

Note

In spectrum analysis the level peak value is always measured.

SAT SPECTRUM

In SAT mode (see corresponding chapter) the whole Sat spectrum of each set satellite frequency plane of 920 ... 2150 MHz can be displayed.
