To provide | To provide users of the early Signal Processing Systems like the [[P7001|DPO]] a way to control the hardware and to write their own measurement routines a programming language was needed. The BASIC language was chosen because it was simple and easy to use. The user could modify their own programs without the need of recompiling it. | ||

This line downloads the data array in memory location A of the DPO to the controller, multiplies each element with the content of variable A and uploads the result back to memory location C of the DPO. The result is automatically scaled to a standard oscilloscope factor. The units of the scale factor are also maintained. So in case the variable A is also an array of waveform elements the result unit will be changed to "VV" (Volts*Volts). | This line downloads the data array in memory location A of the DPO to the controller, multiplies each element with the content of variable A and uploads the result back to memory location C of the DPO.

APD Basic was renamed to TEK Basic and the special variants were called DPO (Digital Processing Oscilloscope) Tek Basic and WDI (Waveform Digitizing Instrument) Tek Basic. | ||

The new TEK SPS BASIC provided a base package which then could be extended with instrument-specific driver and command packages. | ||
