Binary transfer of eye diagram data

Eye Format Waveform Data (CGS)

Returns color grade/gray scale database values in ASCII or binary (16-bit integer) format. Color grade/gray scale data is transferred as a two dimensional array consisting of 521 rows by 751 columns for a total number of 391,271 points. This array corresponds to the graticule display, where each point contains a sample hit count. The array is transferred column by column, starting with the lower left corner of the graticule.

The time for any column of data points:: X_time = (X_column)(X_increment) + (X_origin)
To amplitude for any data point at a given row:: Y_amplitude = (Y_row)(Y_increment) + Y_origin
