4.4.2 UDP Test Mode
The UDP Test Mode can be switched on using the SETSREAMCONTROL
instruction. In Test Mode the streamer periodically generates UDP test
packets. The ADC Data field is filled with a test pattern. The delay between
two UDP packets can be set using the SETUDPTESTCLOCKDIVIDER
instruction.

= (UDP Test Clock Divider Value + 1) / 156250000 second
In Test Mode the sample counter is zero in the C&C header. The ADC data
content of the test packets are the same. The first octet (first eight bytes) of
the test pattern is h0001000100010001. This value is incremented by
h0001000100010001 during the octets.
