2. If a real-time modulation format or the real-time modulation filter feature in Dual ARB is being
used, press the Data Type softkey.
In this menu, select whether the real-time baseband data from the signal generator is either
filtered (Samples) or unfiltered (Pre-FIR Samples). The selection is dependent on the test
needs. The Samples selection provides FIR filtered baseband samples according to the
communication standard of the active modulation format. This is the preset selection and the
one most commonly used. However if the device being tested already incorporates FIR filters,
the Pre-FIR Samples selection should be used to avoid double filtering.
3. Select the data type that is appropriate for the test.
4. Press the Numeric Format softkey.
From this menu, select how the binary values are represented. Selecting 2’s complement
allows both positive and negative data values. Use the Offset Binary selection when
components cannot process negative values.
