clipboard format (i.e. numeric lists). this enables wave - forms to be imported from spreadsheets such as excel and from mathematical programs such as mathcad. values are automatically normalised and re-scaled. waveform export creates multiple clipboard formats of text (normalised numeric values between 1), bitmap (as per on-screen display) and picture (metafile retaining waveform vector properties). note: pictures or bitmaps can be pasted into programs such as word for documenta- tion purposes. display area and printing multiple waveform windows can be open simultaneously. each window is fully scaleable. variable zoom is provided with panning from a ?navigator? sub-window. waveform section limits can be defined via moveable cursors which can be dragged or positioned numerically. waveforms can be printed with automatic annotation and scaling. management and utilities projects to maintain good housekeeping, waveforms can be organised into ?projects? with sepa - rate directory structures. each project maintains its own library of expressions. wave - forms and expressions can be imported and exported from other projects. instrument setup the instrument setup screen enables options for the waveform generator to be set from the program. examples of settable options are output amplitude, clock frequency and trigger source. help full on-screen help is available with a hyper linked contents table. thurlby thandar instruments ltd . glebe road, huntingdon. cambs. pe29 7dr united kingdom (uk) tel: +44 (0)1480 412451 fax: +44 (0)1480 450409 email: sales@ tti-test.com web: www. tti-test.com
