While the marker is moving along the trace, the power (dB) and the probability
(%) will be reflected at the lower left corner as shown in Figure 9-5. Row 1 shows
the reading for Marker 1 while row 2 shows the reading for Marker 2. The lower
right corner shows the delta reading for Marker 2-Marker 1, average
measurement, peak measurement and the peak-to-average ratio for the
respective channel that you have selected.
Step 3: Setting the scale/div
– You are allowed to optimize the view of the trace by setting the appropriate
scale/div. The lowest limit is 0.1 dB while the highest limit is 50 dB. A warning
message will appear if the lower or upper limit has been exceeded.
The alphabet in the parenthesis after Average, Peak and Peak-Average
measurements represents: (A) - Channel A, (B) - Channel B, (G) - Gaussian, and
(R) - Reference.
