           III.    Software should provide flexible experimental setup for sequencing capabilities, useful for:

a.    Unattended, sequenced experimental control, with loops and delays within the sequence.

b.    Charge/discharge/EIS sequences in battery research, or loops of a particular experiment to monitor trends over time.

c.     Building custom waveforms, such as custom pulse trains with numerous steps at user-defined values or custom scans at differing scan rates and vertices.

d.    Controlling ancillary equipment (such as a water bath controller or multiplexer) between experiments to control other external instruments, without interrupting the main experiments running in between.

           IV.   Software should have export/import capabilities for all text-based data files with other software packages such as spreadsheets, word processing packages etc.

            V.   Software should have Copy/Paste feature for data and graphs that need to be exported to document, spreadsheet, or presentation.

           VI.   Software should have provisions to generate publication-quality graphics with the ability to change fonts, colors, symbols, etc.

          VII.   Software should have the ability to overlay data from different experiments, previously acquired data for spot comparisons etc.

         VIII.    Software should preferably have the ability to control and data acquisition of the system with customer-written programs using other programming packages such as LabView, C++, C#, VB etc.  

15.    Accessories
