5.3 Command Panel
The Command Panel is illustrated in figure 5.5. The Command Panel is organized into three
groups: commands and queries requiring data input, commands with only command syntax, and
commands with only query syntax. The Output frame on the right of the window echoes the
SCPI command used to communicate with the power supply. This feature provides the user with
the proper syntax for each command. The Output frame can be cleared or saved to a file by
pressing the clear button or the save to file button. Commands in gray are not accessible with the
particular configuration.
5.4 Register Panel
The Register Panel is illustrated in figure 5.6. The Register Panel graphically represents the six
internal registers of the power supply. Register functions, as covered in the previous Chapter, are
briefly summarized below:
1.
Operation register (oper): indicates the power supply’s current operational state. The
register is unlatched and is described in Section 4.3.4.1
2. Questionable register (ques): indicates the current state of power supply alarms. The
register is unlatched and is described in Section 4.3.4.2.
3. Status Byte register (STB): indicates communications error messages. The register is
latched and is described in Section 4.5.4.
4. Service Request Enable register (SRE): a mask register for the STB. The register is
described in Section 4.5.5.
5. Standard Event Status register (ESR): a latched register which is similar to STB except it
provides more details. The register is described in Section 4.5.2.
