Permits to switch from terrestrial (5-862 MHz) to satellite
band (900-2150 MHz) and vice versa.
Defines the frequency range displayed between Full (the
entire band), 500 MHz, 200 MHz, 100 MHz, 50 MHz, 32
MHz, 16 MHz and 8 MHz (the latter two only for terrestrial
bands).
Defines the reference level between 70 and 130 dBµV in
10 dB steps.
(Only analogue channels, level measurement mode and
single marker mode). Enables dual markers to be shown
on the displayed spectrum.
(Only in dual marker mode). Selects marker A as the
active marker (tuneable).
(Only in dual marker mode). Selects marker B as the
active marker (tuneable).
(Only in dual marker mode). Activates the single marker
on the displayed spectrum.
Offers a choice of spectrum mode sweep rates: Fast (fast
sweep, low accuracy), High Resolution (slow sweep,
high accuracy) and Antenna Alignment (tool for faster
sweep antenna
representation).
(Only in C/N measurements). Permits to define the
frequency where noise level will be measured (see
Carrier function).
define channel bandwidth (see Marker function).
(Only when measuring Channel power and after defining
the Channel bandwidth). Permits to change the tuning
frequency by means of the rotary selector.
(Only when measuring C/N Referenced and after defining
the Reference noise). Permits to change the tuning
frequency by means of the rotary selector.
