field change also.) In the Top field, type 0.1. In the Bottom field,
type –0.1.
You can now click the Go button to run the sweep. A graph is created, and
the response is plotted as the sweep progresses. If you are monitoring using
the internal speaker, you will hear the analog generator frequency step through
the audio range. The result will be a response curve that deviates only slightly
from 0 dBV, as shown in Figure 25.

Example Sweep: Amplitude Linearity
For this example, we will measure the amplitude linearity of the 2700 series
instrument. With the Analog Generator output connected to the Analog Analyzer
input, we sweep the amplitude of the Analog Generator over its full
range, and plot the ratio of the level measured by the Analog Analyzer Level
meters to the generator output level, in dB. Any amplitude non-linearity in the
system will show as a deviation from 0 dB.
First, click New Test, turn the Analog Generator ON, and set the Analog
Analyzer Source A and B to GenMon so that the generator signal is sent di-
