  • Page 28: Installation

    To properly install and power on the instrument, perform the following steps: 1. Check that the operating environment is correct. The DG2030 operates correctly in ambient temperatures from +10_ C to +40_ C and relative humidity from 20% to 80%. If the instrument is stored at temperatures outside this usage temperature range, do not switch on the power until the chassis has come within the operating temperature range.
  • Page 29 CAUTION. The DG2030 is shipped with a power cord appropriate for use with normal 115 V power systems. If the DG2030 is to be used with 230 V power, the power cord must be replaced with one appropriate for the power source used.

  • Page 44: Data Structure Overview

    Data Structure Overview 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.

  • Page 46 Pattern data can be divided into blocks. A block is a user-specified range of pattern data identified with a unique label. Blocks are divided by setting delimiters called block delimiters. Block delimiters are set in word units. Sequences, which are described later, control data output in block units. 2 12 DG2030 User Manual...

  • Page 47: Operating Modes Overview

    Run Modes In the run modes, pattern output is controlled by the pattern generation unit’s pattern control circuit. The DG2030 supports four run modes: repeat, single, step, and enhanced. These run modes are specified with the SETUP → Run Mode menu. Table 2-3 provides functional information for each mode.

  • Page 48: Table 2-4: Update Modes

    NOTE. The response to edit operations while in Auto mode may be slow when there is a large amount of data being edited. In such cases, it is more efficient to perform a number of edit operations and then update the output data in manual mode. 2 14 DG2030 User Manual...

  • Page 55: Pattern Data Display Format

    You can display pattern data in one of three formats: timing display, table display, and binary display. Use the EDIT ! Settings item to select the display format. Figures 2-14 through 2-16 show the three display formats. Figure 2 14: Timing display format 2 21 DG2030 User Manual...

  • Page 56: Figure 2-15: Table Display Format

    The Binary display format shows the data bit states for each clock as 0 or 1. This is the basic display for digital signals, and is an appropriate format for handling data in bit units. If no groups are defined, data can only be displayed in binary format. 2 22 DG2030 User Manual...

  • Page 57: Edit Operations

    Another problem is that the screen area is not large enough to make selections from the editing operations menu items while checking the data being edited on the screen. The DG2030’s user interface was designed with these points in mind. The DG2030 pattern data editing functions separates the selection and execution of editing operations.
