The Analog Signal Path Chapter 5: Quick Guides
Controlling the Analog Generator
The topmost two fields in the Analog Generator panel control the generator
waveform. The Analog Generator is capable of producing sine waves, square
waves, noise and other waveforms. At this point the waveform should be set to
Sine: Normal (Sine in the left field, that is, and Normal in the right). Drop
down the left-hand list box and choose Square to change the waveform to a
square wave. If you are monitoring the signal with the internal speaker, you
will hear the timbre of the signal change. You will also see the signal level
change in the Analog Analyzer panel. (A square wave has a higher rms level
than a sine wave for a given amplitude setting.)
The square waveform has one parameter or setting available: the frequency.
This is set in the field below the waveform selection fields. We will now
change the generator frequency to 2 kHz, as follows:
Figure 21. The Analog Generator.
Click in the Frequency field in the Analog Generator panel. The text
1.00000 kHz becomes highlighted.
Use the keyboard to type 2k, the new generator frequency. As you can
hear in the monitor speaker, the frequency does not change.
Now press the Enter key. The text changes to 2.00000 kHz, the pitch increases
from the monitor speaker, and the frequency reading in the Analog
Analyzer panel changes to about 2 kHz.
Now switch the waveform type back to sine. The current square wave frequency
is used for the sine wave.
You can enter standard SI prefixes for multipliers as you
enter the value in the setting field. For example, ‘2000’, ‘2k’,
‘0.002M’, and ‘2000000m’ all produce the same frequency.
All waveforms can be generated at any amplitude from 0 V to the maximum
output voltage of the instrument. The amplitude for each channel is controlled
by fields below the OUTPUTS field. If the Track A checkbox is checked, the
