To check a created signal
This section assumes you have created a signal as shown on the previous
page, have not changed any setup parameters, and have not preset the
instrument.
This task uses digital demodulation. If you want to perform this task using
video demodulation, choose video demodulation instead of digital
demodulation in step 4.
1. Connect the source output to the channel 1 input and play the signal through
the arbitrary source:
Press [
Source
], [
source on
], [
source type
], [
arbitrary
]. The default data register is
D1.
2. Select the optimum range:
Press [
