| Data Acquisition Options |
0 | Go on-line, light indicators, set up tables, etc., notify operator when done. |
1 | Put digitizer in initialization mode. Parameter input establishes identification for experiment and ordinate/abscissa input is displayed on the CRT screen. |
2 | Go off-line, turn off indicators. |
3 | Activate digitizer, release spectrometer scan, turn alarm off. |
4 | Inhibit digitizer interrupts, release spectrometer scan. |
5 | Prepare for start of data acquisition, check for completion of initialization and availability of disk space. |
6a | Set up experiment for repetitive scan (15 max). |
7a | Prepare to back up and repeat a spectral region. |
8a | Prepare to change the interval of digitization at the beginning of the next sector of input. |
9 | End experiment at current point. |
10 | Abort present experiment and update index to experiments. |
11a | Recover from core wipe out. System goes back to last filled sector on disk of experiment last entered in the index and sets up for resumption of data acquisition. |
12a | Check the ordinate encoder sequencing of a special experiment in which the interrupt rate is set very high and the ordinate is slowly varied from one extreme to the other. This option checks to see that no ordinate value is greater than one unit away from the preceding value. Misses are recorded on the CRT. |
13 | Turn off the audible alarm. |
14 | Notify system of LO absence so that messages that occur during absence may be saved. |
15 | Notify system of LO return. If messages have occurred, the system displays them and the time of their occurrence. |
16a | Choose new low wavelength limit for ending data acquisition. |
17–19 | Not used. |
| Data Display Options |
20 | Display initialization data in core. |
21a | Display initialization data of any experiment on disk. |
22 | Display initialization data and spectrum in the current data table being acquired. |
23a | Display initialization data and spectrum in any sector of any experiment on disk. |
24 | Display a table of disk resident experiments and their starting sector addresses (all experiments are packed). |
25–29 | Unused. |
| Data Reduction Options |
30a | Remove an experiment from disk. If it is the last experiment in the area, it is merely removed from the index. If it is between experiments, all following experiments are relocated to close the gap. |
31a,b | Plot up to 10 experiments on a single graph. The operator determines the number of wavenumbers per inch and the ordinate interval (0 to 1000 or any 20% interval full scale). Infrared and Raman data may be plotted on top of one another. The wavelength interval from 2000 cm−1 to 4000 cm−1 may be compressed by any factor relative to the 0 to 2000 cm−1 interval. |
32a | Digitally filter the data in an experiment with a 5, 7, 9, 11, 13, or 15 point cubic convoluting function.1 If the experiment being smoothed has been transformed by previous options (has a negative experiment number), it may be operated on and placed back in the same disk area. This process may be done a fixed number of times or repetitively until the ordinate changes by one or less on successive smooths. |
33a,b | Transfer an experiment to the magnetic tape experiment library from disk. Only allowed if it is not already on tape. |
34a,b | Transfer an experiment from magnetic tape to disk and update the index. Only allowed if it is not already on disk. |
35a | Normalize a spectrum so that the strongest Raman line has a maximum value of 1000 or so that the highest value of percent transmission of an infrared experiment is 100% (1000). |
36a | Produce an averaged experiment from a repetitive scan experiment. |
37a | Correct the intensities of a Raman experiment for nonuniform spectrometer and photomultiplier response. This requires that the spectrometer response to a standard lamp be available as a separate experiment on the disk. |
38a | Scale an experiment by an amount X/Y. X and Y are input integer numbers. |
39a | Subtract experiment A from experiment B, and store on A, B, or C. A and B must be of identical length. |
