Channel Spectrum: Opens the “Channel Spectrum Menu” on page 6-35 .
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.
Power vs. Time: Opens the “Power vs. Time Menu” on page 6-35 .
Displays the Power vs. Time graph showing the signal in the time domain.
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: Opens the “Spectral Emission Menu”
on page 6-36 . 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.
