FUNCTIONS
4.2.10.1.
Demod BW
(Demodulator Bandwidth)
The demodulator bandwidth allows a clearer demodulation
of individual signals. With it, the demodulation bandwidth
can be adjusted according to the signal width. For FM for
example you should select a rather high bandwidth of about
500kHz, for AM, the bandwidth can be considerably narrow
-
er (for example, 20 kHz). Ultimately you will have to exper
-
iment to find the perfect bandwidth for each demodulation.
4.2.11. Marker
(
Cursor)
ONLY available in real time mode
With the cursor you can exactly determine the frequency of
single signals in the spectrum.
After the activation, you will automatically get to the spec-
trum display, where a thin red/black dashed cursor will be
displayed. At this point, the frequency will display the signal
in the „DTS Parameter“ window. You can move the cursor
back and forth with the jog dial to move it anywhere in the
spectrum in order to approach specific signals .
To disable the cursor you only have to enable the menu item
Marker again.
4.2.12. Load & Save
(
Load and Save the Setup )
ONLY in soft mode
With Load and Save you can save up to 10 individual soft
displays in the memory of the SPECTRAN. Here different
parameters of the soft displays (also for a two- or four-fold
constellation) are saved. This data will be saved for each
soft display:
- Center frequency (respectively start and stop frequency)
- Span
- Attenuator
- Preamplifier
- Sweep time
- Dynamics
- Reference Level
- Display Mode
- Limits
