Use this tab to configure the Data Outputs (Channel 1, Channel 2, Channel 3, and
Channel 4) of the M8195A AWG module.
The M8195A has six different modes of operation:
Single Channel: If this mode is selected, Channel 1 is used to generate
data; Channel 2, Channel 3, and Channel 4 are disabled.
Single Channel with Markers: If this mode is selected, Channel 1 is used
to generate data, and channel 3 and 4 are used to generate digital
markers. Channel 2 is disabled. The memory mode for Channel 1 is
‘Extended’ and cannot be changed.
Dual Channel: If this mode is selected, Channel 1 and Channel 4 are used
to generate data. Channel 2 and Channel 3 are disabled. This mode is
selectable, if option 002 or 004 is present.
Dual Channel Duplicate: If this mode is selected, Channels 1, 2, 3 and 4
are used to generate a signal. Channel 3 generates the same signal as
channel 1. Channel 4 generates the same signal as channel 2. The
memory mode for Channels 1 and 2 is not configurable and is always
‘Extended’ memory. This mode is selectable, if option 002 or 004 is
present.
Dual Channel with Markers: If this mode is selected, Channels 1 and 2 are
used to generate a signal. Channel 1 has two markers output on channel
3 and 4. Channel 2 can generate a signal without markers. The memory
mode for Channel 1 is not configurable and is always ‘Extended’ memory.
This mode is selectable, if option 002 or 004 is present.
Four Channel: This mode is only selectable, if option 004 is installed. If
this mode is selected, all four channels can be used to generate data.
Sample Rate Divider (Extended Mem):
The speed of operation of the extended memory is adjustable using the
parameter ‘Sample Rate Divider (extended memory)’. Possible values are 1, 2,
and 4. The sample rate divider is identical for all channels that are sourced
from extended memory. In case the sample rate divider is adjusted to two or
four, the FIR filters are used as interpolation filters by factors of two or four.
The interpolation is necessary as the DAC always operates in the range
53.76 GSa/s … 65 GSa/s.
