Sweep Field
The Sweep phase of the scan step occurs last and consists only of measurement operations. These
measurements can be performed on any of the channels which have the ability to connect to the
DMM via the backplane (see the EX1200 Switch Card User's Manual for information regarding
switch card capabilities). After clicking on the white entry box, the user can 1) click on the black
configuration button on the right to start the Sweep Wizard (see Figure 7-7). or 2) enter a valid
sweep sub-step string directly into the box. The wizard allows the user to scan any from any
connected switch card, in ascending order, and allows for one DMM configuration to be selected
per channel. The buttons and menus available in the wizard provide the following functions:

Function drop menu: By selecting a specific function from this drop menu, the Sweep
Wizard will only show channels that are capable of performing the selected DMM function.

Only show configs... check box: When selected, the Sweep Wizard menu will only display


