Channel Spectrum:
Displays the spectrum of the input signal. Beneath the
graph, values for the following measurements are displayed: Channel Power
and Occupied BW. Channel Power is displayed in dBm or Watts (based on
the Units submenu setting in the
Amplitude
menu) and Occupied BW is
displayed in MHz. Press this button again to list the Channel Spectrum menu
to set the Span.
Span:
Opens the Span list file to select a frequency span or Auto.
Back:
Returns to the RF Menu.
ACLR:
Displays a bar graph of the main channel power and two adjacent
channels on either side. The table underneath the chart lists the frequency,
power, and power relative to the main channel (in dB).
Spectral Emission Mask:
The Spectral Emission Mask measurement
supports the testing for “Operating Band Unwanted Emissions” described in
the 3GPP TS 36.141 Base Station Conformance testing document. There is
support for Category A and Category B (Option 1 only) masks which are
automatically selected based on the current carrier frequency/channel and
BW values.
The instrument indicates if the signal is within the specified limits by
displaying PASS or FAIL. The emission mask information is also displayed in
a table format with different frequency ranges and whether the signal
PASSED/FAILED in that region. Press this button again to list the Spectral
Emission submenu.
Category A B (Opt. 1):
Select the desired category based on the
information above.
Select Mask (Auto):
Displays a list of standard and custom masks for
use in SEM measurements. Select “Auto Select” if the desired mask is
unknown.
Summary Table:
Displays the Spectral Emission measurement data
in table form.
Back:
Returns to the RF Menu.
