� CENT CENT CENT CENT, centre frequency range is from 955MHz to 2145MHz. If the input frequency is above
2145MHz, S7000 will indentify if the input frequency is valid C band or Ku band, if valid, S7000 will
calculate the SAT-IF automatically.
For For For For example: example: example: example:
Input 1938MHz, 1938MHz is in centre frequency range, this value is valid.
Input 12538MHz, this is a valid transponder frequency in Ku band. If the LNB local osc has been set
as 10600MHz, S7000 can calculate the centre frequency is 1938MHz.
Input 6000MHz, this is invalid frequency, so S7000 will give it up and reset the centre frequency to
the maximum frequency.
� SPAN SPAN SPAN SPAN, spectrum span, (10MHz-1200MHz).
� Scale Scale
Scale Scale, level scale, (1dB/, 2dB/, 5dB/, 10dB/).
� � � � REF REF
REF REF, reference level, range is from 20dBuV to 120dBuV. Press
input digital num key directly.
�
THLD THLD THLD, noise threshold range is from -20dBuV to 120dBuV, S7000 only display the spectrum above THLD
the noise threshold as shown in Figures 4-9 and 4-10.
� MARK MARK MARK MARK, Marker, as shown in Figure 4-11.
