Data is written to the target data file in a columnar format. A maximum of thirty one columns may be written depending upon the number of waveforms in the data file. When the WinDaq Waveform Browser is exited and a notepad file is typed to the screen or printed, the columns seen are defined as follows:
|
COLUMN 1 (left-most) |
Time-to-beginning-of-file |
|
COLUMN 2 |
Time marker |
|
COLUMN 3 |
Channel one data |
|
COLUMN 4 |
Channel two data (if available) |
|
COLUMN 5 |
Channel three data (if available ) |

COLUMN 31 (right-most) |
Channel twenty nine data (if available) |
Data for all waveform channels, time-to-beginning-of-file, and time marker data are all written to the notepad file whenever the NOTEPAD function is invoked.
All data will be written in scientific notation format. The only exception to this rule is time marker data. If a time marker was enabled at the time the NOTEPAD function was invoked, time marker data will be annotated in scientific notation. If the time marker WAS NOT enabled, column two will contain nine zeros 000000000 indicating that the time marker was not enabled.
If Engineering Units was enabled for a channel (or channels), the data written to the notepad file will be in engineering units. Channels that have not been enabled for engineering units conversion will be written as raw analog voltages.
When the NOTEPAD is activated with a compressed waveform display, waveform values reported to the notepad file will be the minimum, maximum, mid point, or minimum/maximum value of the waveform's line segment that is coincident with the cursor depending on the state of the cursor mode. Refer to Waveform Compression for details related to the function and operation of the cursor mode with compressed waveforms.
All NOTEPAD files are directly compatible with LOTUS 1-2-3, ASYST, and ASYSTANT. In the case of the latter two, the notepad file will have to be converted from ASCII into the ASYST/ASYSTANT format before being read. ASYST and ASYSTANT provide the file conversion utilities.
