Summing Two

Signals

BASIC (RGBSUM)

This program uses the E1446A to sum the signals from two E1445A AFGs. The AFGs at logical addresses 72 and 80 generate 1 Vpp, 5 kHz and 100 kHz sine waves respectively. The signal from the AFG at logical address 72 is applied to E1446A ’Input 1’. The signal from the AFG at logical address 80 is applied to ’Input 2’. All three devices are in the servant area of the V/360 embedded controller.

Note that this program uses the subprograms contained in the file ’SUMSUBS’. A description of ’SUMSUBS’ follows the listing of the example subprograms.
