Quick Start Guide
Making a Basic Measurement
4. Set the amplitude.
a. Generally, placing the signal peak at the reference level provides
the best measurement accuracy. To adjust the signal peak to the
reference level ( Figure 1-8), press
AMPLITUDE. Then key in 10
dBm, or use either the step keys or the knob.
Using the knob is the easiest way to fine-tune the signal peak to
the reference level, which is located at the top of the graticule.
b. Because the marker is active, a faster method to fine-tune the
signal peak to the reference level is to press
MARKER REF LVL,
which is located under the
MKR key. This function sets the
reference level equal to the marker amplitude value.
