softkey. (This softkey is inactive when an ARB modulation format is turned
on.)
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 depends on the test needs. The Samples selection provides FIR
filtered baseband samples based on 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.
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.
