•
Transmit Path: Indication and adjustment of Gain, Phase and Offset values.
•
Error Mask: Tick the box to un-mask Tx path error status bits. The total number of errors for un-
masked conditions is displayed in the ‘Arithmetic errors’ box when a Tx sequence is completed. The
Tx function will be aborted if the error count reaches 255.
•
Data Source:
•
The random data is generated from a 15-bit sequence with XOR feedback from bits 14 and 15.
•
Small sequences ( <2048 symbols ) can be transmitted from a text file. For file format see the
additional information section.
Data is transferred to the DSKplus in 2048-symbol blocks.
Hints:
•
For Tx to work, values must be written to the gain registers.
