Example Custom Signal Emission Mask

To create a custom SEM, use the following steps:
1. Export the existing mask as a csv file by pressing the EXPORT MASK button in the SEM SETUP menu.
2. From the FILES menu, move the exported file to a USB device and then to a computer for editing.
3. If this is the first time exporting the file, the following data should be in the file:
# Example Custom Signal Emission Mask
# Start Frequency, Stop Frequency, RBW, VBW, Is Start Amplitude Relative, Is
Stop Amplitude Relative, Start Amplitude, Stop Amplitude
-3.5e6, -2.1e6, 100e6, 100e6, 0, 0, -9.5, -9.5
-2.1e6, -0.7e6, 100e6, 100e6, 0, 0, -9.5, 0.5
0.7e6, 2.1e6, 100e6, 100e6, 0, 0, 0.5, -9.5
2.1e6, 3.5e6, 100e6, 100e6, 0, 0, -9.5, -9.5
4. Change each of the values as desired. Note that the values must be entered in the listed order of the file
header.
5. Save the file to a USB device and insert it into the instrument.
6. Select the IMPORT MASK button in the SEM SETUP menu and select the new file from the USB drive.
The file name of the imported mask file will be displayed on the EXPORT MASK button.
7. Select the SELECT MASK button and select Custom.
Spectrum Analyzer MG
SELECT MASK: Selects the desired upper or lower emission mask:
• 5GNR(KR) P < 38 dB
• 5GNR(KR) P > 38 dB
• Custom
IMPORT MASK: Used to import a custom user mask.
EXPORT MASK: Exports an example user mask as a comma separated value file (see
"Example Custom Signal Emission Mask" on page
custom mask.
REF CH BW: Sets the reference channel bandwidth for the measurement.
AUTO MAX PWR: Toggles automatic max power. Some segments in the mask are
dependent on the main channel power. Enabling this automatically calculates the
reference channel power by measuring the channel power of the center channel
bandwidth. When disabled, the reference power must be entered manually below.
MANUAL MAX PWR: Used to manually enter the reference channel power for masks
that have limits dependent on main channel power.
PRESET SETUP: Presets all values on the SETUP menu to default values.
