The Analog Signal Path Chapter 5: Quick Guides
In the default configuration, the Analog Generator panel is set for a 1 Vrms,
1 kHz sine wave, but the analog outputs are disabled. To turn on the outputs,
click the OUTPUTS OFF button near the center of the panel. The button will
turn green, and you will hear relays click in the instrument hardware. The
Level meters on the Analog Analyzer panel will show approximately 1.000 V.
The Level meters show the rms level of the signals at the analog inputs.
The stereo Analog Generator outputs can be individually disabled with the
CHA and CHB buttons next to the OUTPUTS field. Click on the CHB button.
The button will turn gray, relays will click in the instrument, and the
Channel B Level meter on the Analog Analyzer panel will indicate a level of
0.000 V.
Now that we’ve successfully routed a signal from the Analog Generator to
the Analog Analyzer, we will perform some basic measurements.
Using the Analog Analyzer
The 2700 series has two independent general-purpose analyzers that can
perform measurements on analog signals. We will be using the Analog Analyzer
for the Quick Guide; the alternative DSP Audio Analyzer is an analysis
tool available on the Digital Analyzer panel that offers similar analysis capabilities.
You can read about the both analyzers in Chapters 8 and 10 of the
2700 Series User’s Manual.
The Analog Analyzer is an analog-domain real-time audio analyzer, implemented
in instrument hardware. It provides continuous readings of signal level
and frequency for both input channels. It also allows you to select a channel
and apply filtering to it, and to measure parameters such as total harmonic distortion,
phase, and so on.

set OFF in this illustration.
At this point, you should have the setup shown in Figure 19:
