7.4 Level measurement
During each sweep, the level of the cursor frequency is measured and displayed at the top right of
the screen in dBµV. Level measurement in analyzer mode is comparable to that of a pure spectrum
analyzer. The power within the measuring bandwidth (RB) is measured and converted into dBµV as
a level. On the other hand, the level measurement in measuring receiver mode always measures the
power (level) in the channel.
7.5 Progress bar
A yellow bar at the bottom of the screen runs from left to right during each new search by the
analyzer. This allows you to trace the progress of the sweep.
7.6 Switching to measuring receiver mode
You can switch directly from analyzer mode to measuring receiver mode. The instrument uses the
current cursor frequency to tune the measuring receiver. However, frequency segment SPAN1 or
SPAN2 must be set.
Press
ENTER
to begin the process.
When the UNICABLE control is active, the frequency display always refers to the spectrum that was
converted by the UNICABLE unit.
If the
ANALYZ
button is then pressed again, the instrument returns to analyzer mode.
7.6.1 Switching to measuring receiver mode with SCAN
A menu will appear as soon as the scan button is pressed, here you can choose between
SAT
SCAN
and
TRANSPONDER SCAN
. Access for this function can be obtained by pressing either the
SCAN
or
ENTER
button.
7.6.2 Transponder SCAN
Depending on the respective SPAN, the following additional functions are executed when the
SCAN
button is pressed.
FULLSPAN: Starting from the current cursor position, the next maximum is searched and the centre
frequency of this transponder is determined. The analyzer then switches to SPAN1 with
the frequency it has determined as the cursor position.
SPAN1:
As is the case with FULLSPAN, the centre frequency of the next transponder is
searched and tuned to. In addition to the five preset symbol rates, the entire range of
the symbol rates is searched from 2 to 45 MSym/s.
