The narrowest band of
this table is 1.9 MHz wide
(set1: from 0.100 MHz to
2.000 MHz).
The other bands, being
very wide, would not
activate a filter as narrow
as the one for the first
band.
Starting from 100 kHz

In the low range part, a too narrow frequency range, could introduce a
continuous component, falsifying in this way the measure.
At the same time, in the high range part, a too wide frequency range
will activate a too wide filter, causing the raise of the noise floor. In
this way a low signal could be confused with the noise floor itself.
Each data input or change can be confirmed clicking on the "Save" button.
Eventual setting errors will be notified with a message.
When using the AMS8061 EHA-2B dual band antenna, and, in general,
when frequencies below 1 MHz are to be measured, the band table
should be defined in order to avoid measuring the "0Hz" signal which
exist in every spectrum analyzer.
Every spectrum analyzer displays the 0 Hz signal every time the RBW
filter is larger than half the minimum frequency to be measured.
To
achieve
a
measurement accuracy, the AMS-8061 sets automatically the larger
RBW filter, which allows at least 4 measurements during the scan of
the narrowest band of the table.

Since the system is very flexible and open, when setting the
frequency bands, the User must be conscientious of what he is going
to do.
Parameters incompatible with each other can cause system crashes
and inconsistent readings.
