The output channels support a function that sets their outputs to the high-imped-
ance state. Inhibit level and inhibit control can be set, as parameters, for each
output channel. For all channels, the external or internal inhibit signal, or the
logical OR of those two signals can be selected as the high-impedance control
signal. Channel 0 controls the internal inhibit.

Data Output
T : The delay time from an external inhibit input or a CH0 signal until the corresponding data

output goes to the high impedance state, or the delay from the high impedance state until
high or low level data is available. Refer to Figure A 2 on page A 5 for more information.

The display and front panel implement the user interface.
The display is a 16-level monochrome 640  480 pixel CRT. The front panel
consists of menu buttons, numeric keys, bezel buttons, a general-purpose knob
for changing numeric values and item selection, and several signal output
connectors.
To make full and efficient use of the DG2030, you need to understand the
DG2030 data structures. This section presents an overview of the pattern data,
setup data, and sequence data. Figure 2-8 shows the DG2030 data structures that
are described in the following sections. Table 2-2 lists the data structure related
technical terms that appear frequently in the operating procedure descriptions.
