Using Combined Signed Data
The Combined Segment Lists transfers both the arbitrary waveform
segment data and marker pulses to the AFG (see Chapter 6 for information
on marker pulses). You can use either the Signed or Unsigned number
format for the list.
The Combined Segment List can be sent as a comma separated list (see “Using
Signed Data to Generate Waveforms” on page 225), or as Definite Length or
Indefinite Length Arbitrary Block Data (see “Using Definite Length Arbitrary
Blocks to Transfer Data” on page 231 and “Using Indefinite Length Arbitrary
Blocks to Transfer Data” on page 235, respectively).
This section shows how to transfer the lists as DAC codes using the Signed
number format.
Note The AFG can only accept a single number format at a time. Thus, if the
AFG currently contains Signed data and you wish to send Unsigned data,
you MUST delete the data in memory first before enabling the AFG to
receive Unsigned data.

List Format
Refer to Figure 7-1 for the 16-bit Integer Combined Segment List. Bit 1 (bit
value 2) sets the marker pulse. Bits 3 to 15 are the DAC codes.
