Spectrum emission mask measurement with spectrum analyzer
If Lower Peak or Upper Peak indicates Fail, the mask line becomes red.
NOTE:
If the Trace View is set to Off, the Reference Power, Lower Peak, and Upper Peak is not shown. If the Trace View
is set to On and the Trace Type is selected other than Clear Write, the Reference Power, Lower Peak, and Upper
Peak is shown with value and "*" at the end of the value.
Adjacent channel power (ACP)
The Adjacent Channel Power (ACP) is the power contained in a specified frequency channel bandwidth relative to the total carrier
power. It may also be expressed as a ratio of power spectral densities between the carrier and the specified offset frequency band.
The ACP measures the power of a carrier channel and the power in its adjacent (offset) channels. The measurement results allows
you to determine whether the carrier power is set correctly and whether the transmitter filter is working properly. You can measure
the channel power in from one to five adjacent (offset) channels on the lower frequency and upper frequency side of the carrier
channel. Limits can be used to quickly see if too much power is measured in the adjacent channels.
Setting measure setup
After configuring spectrum measurement in " Configuring Spectrum Measurements ", you can set the measure setup to continue your
measurement. The measurement settings can be saved and recalled as a file by selecting File Type as Setup and load the file onto
the instrument using the
Save/Load icons on the side bar.
1 Tap the Setup ( )icon on the side bar.
2 Tap Configuration to configure an offset, up to five. The below table appears.
You can also tap the Configuration ( ) icon under the chart screen.
a Select Offset from 1 to 5 and switch each to On to display or Off to hide the active offset.
b Select Offset Frequency to set the center frequency of the offset using the on-screen keyboard.
