Figure 5-34, DACs Controls
These controls, shown in figure 5-34, are used to configure the signals that will
appear on the four DAC connectors on the rear panel of the instrument. Each control
has a signal selector; if this is set to User setting then the text box below is used to
specify the corresponding voltage; otherwise it is grayed out.
The controls operate as follows:
DAC1, DAC2, DAC3, and DAC4
These four controls select which signal will be made available at the corresponding
DAC 1 to DAC 4 connectors on the rear panel of the instrument. The following
settings are available, but note that internal connection limitations mean that not all
settings are available for each DAC connector.
