In the
Channel Output Config
window (Figure 47), all channels (Channel 0 to Channel 3) have an output frequency of 10 MHz
(
Frequency 00
box). The
Enable ASF
box is unchecked because a linear amplitude sweep is being performed. The amplitude scalar factor
(
ASF
) is set to 0.5 (half scale), denoting that the sweep begins at half scale and sweeps up to full scale (
Amplitude 01
-ending point of
sweep). In the
Linear Sweep Setup
section, the rising/falling step size and step intervals of the sweep are equal, indicating the sweep will
rise and fall at the same rate.
P0
controls Channel 0,
P1
controls Channel 1,
P2
controls Channel 2, and
P3
controls Channel 3. To sweep
up to full scale, press the profile pin associated with the channel’s output. To return to half scale, unselect the profile pin.
