2. Configure the measurement as required (see also "How to Set Up the Channels"
on page 142).
3. In the "General Settings" tab, select the "Manage User Standards" button to display
the "Manage" dialog box.
4. Define a filename and storage location for the user standard.
By default, the XML file is stored in
C:\ProgramData\Rohde-Schwarz\ZNL-FPL\acp_std\
. However, you can
define any other storage location.
5. Select "Save".
To load a user-defined configuration
1. In the "General Settings" tab of the "ACLR Setup" dialog box, select the "Manage
User Standards" button to display the "Manage" dialog box.
2. Select the user standard file.
3. Select "Load".
The stored settings are automatically set on the R&S FPL1000 and the measure-
ment is restarted with the new parameters.
How to Compare the Tx Channel Power in Successive Measurements
For power measurements with only one Tx channel and no adjacent channels, you can
define a fixed reference power and compare subsequent measurement results to the
stored reference power.
1. Configure a measurement with only one Tx channel and no adjacent channels (see
also "How to Set Up the Channels" on page 142).
2. In the "ACLR Setup" dialog box, select the "Set CP Reference" button.
The channel power currently measured on the Tx channel is stored as a fixed ref-
erence power. The reference value is displayed in the "Reference" field of the
result table (in relative ACLR mode).
3. Start a new measurement.
The resulting power is indicated relative to the fixed reference power.
4. Repeat this for any number of measurements.
5. To start a new measurement without the fixed reference, temporarily define a sec-
ond channel or preset the instrument.
7.2.4.6 Measurement Examples
The R&S FPL1000 has test routines for simple channel and adjacent channel power
measurements. These routines give quick results without any complex or tedious set-
ting procedures.
