Par QI Intrlvd
This softkey enables parallel interleaving of the data samples transmitted, where the Q sample is
transmitted on the rising edge and the I sample is transmitted on the falling edge.

Parallel
This softkey enables parallel data transmission. This is the factory preset port configuration.
SCPI
:DIGital:PCONFig PARallel
:DIGital:PCONFig?
Pre-FIR Samples
This softkey selects unfiltered data as the data type to be transferred through the N5102A module.
When an ARB modulation format is on, this softkey is not accessible. In the Input mode, this data type
limits the clock rate to 50 MHz for filters with a width 16 symbols, and 25 MHz for filters with a
symbol width.
SCPI
:DIGital:DATA:TYPE PFSamples
:DIGital:DATA:TYPE?
If this command is executed while an ARB modulation format is active, the
parameter choice is changed, but it is not used by the signal generator until a
real-time modulation format is turned on.
Because a query returns the current choice, regardless of whether or not an ARB
format is active, you must query both states (data type and the modulation format)
to know the signal generator’s current setup.
Port Config
This softkey accesses a menu that enables you to select a parallel, serial, parallel interleaved IQ, or
parallel interleaved QI data transmission between the N5102A module and the DUT.
