-Configure waveform generator AWG1 as a triangle wave with a frequency of 100 Hz and an amplitude of 10 V with 0 V offset. The scope display should be set in both voltage vs. time and in XY mode with channel 1 on the horizontal axis and channel 2 on the vertical axis. Be sure to turn on the power supply only after you have completed and double checked your connections.+Configure waveform generator AWG1 as a triangle wave with a frequency of 100 Hz and an amplitude of 10 V peak-to-peak with 0 V offset.
