I am using the raw binary format for getting the output sample ,& as you say I am getting the sample outputs in bits but for different input values I am getting the almost
same sample values .

Command:

ts7800ctl –r”0” | dd bs=2 count=1000 2>/dev/null | hexdump –v –e ‘1/2 “%u, “’ > ch0_500_samples.csv

For 0v Input:

30768, 13367, 12336, 12343, 12298, 14200, 12340, 14128, 2608, 30768, 12343, 12336, 13367, 12298, 14200, 12336, 14128, 2608, 30768, 13367, 12336, 13367, 12298, 14200

For 0.5v input:

30768, 13618, 12344, 13618, 2659, 30768, 13618, 12387, 13618, 2659, 30768, 13618, 12387, 13618, 2659, 30768, 13618, 12387, 13618, 2659, 30768, 13618, 12387, 13618

For 1v input:

30768, 13109, 12387, 13109, 2659, 30768, 13109, 12387, 13109, 2659, 30768, 13109, 12387, 13109, 2659, 30768, 13109, 12387, 13109, 2659, 30768, 13109, 12387, 13109

For 2v input:

30768, 12385, 12340, 12385, 2612, 30768, 12385, 12340, 12385, 2612, 30768, 12385, 12340, 12385, 2612, 30768, 12385, 12340, 12385, 2612, 30768, 12385, 12340, 12385

For 2.5v input:

30768, 13923, 12340, 13923, 2612, 30768, 13923, 12340, 13923, 2612, 30768, 13923, 12344, 13923, 2616, 30768, 13923, 12344, 13923, 2616, 30768, 13923, 12344, 13923

now how to find the digital output corresponding to analog input because there are so many samples corresponding to each input & they all are same for each input??

one more thing every time the first sample is 30768 what does this means ???
