Interpolation Factor
One of 3 frequency interpolation types (1X, 2X or 4X) may be set for either
channel pairing.
The interpolated sample rate of each channel pair can be calculated as a
combination of the internal DAC's sample rate (250 MS/s for both
Arbitrary and DDS projects) and the frequency interpolation's factor.
The maximum interpolated sample rate is 1 GS/s and can be achieved by
selecting a 4X interpolation factor.
Clock Source
The clock source may be set to Internal or External.

If Internal is selected, the clock signal is generated internally.

If External is selected, the clock signal from the EXT CLOCK BNC
connector is used. When the External Clock is selected, an External
Clock Frequency must be set for your clock signal.
Multi Device Deskew Delay (1104 with Expansion Bus
option only)
This parameter can set a fine delay between multiple devices in order to
compensate the skew between the outputs belonging to different devices.
The skew delay is only active on Slave devices and can add a positive delay
respect to the Master.
When deskewing the channel delay of a slave device with respect to the
master, the Multi Device Deskew delay must be used in conjunction with
the trigger delay. Multi Device Deskew delay sets a fine delay and can only
be positive, while the trigger delay sets a normal delay and can also be
slightly negative.
The deskew delay is only effective when all devices work with the same
sampling frequency that must be in the following list: 250 MHz, 200 MHz,
150 MHz, 100 MHz, 75 MHz, 50 MHz, 37.5 MHz, 25 MHz.
