Keithley 2701

Model 2701 User’s Manual Scanning 7-11
Scan configuration
A scan is configured from the scan configuration menu which is accessed by pressing
SHIFT and then CONFIG. Figure 7-3 shows the basic flowchart to configure a scan. After
entering the menu structure you can configure a simple scan, an advanced scan, or reset
the configuration to the default setup for a simple scan. Refer to the flowchart in
Figure 7-3 for the following discussions on “Scan reset,” “Simple scan,” and “Advanced
scan.”
NOTE Only a sequential scan can be configured from the front panel. For a sequential
scan, the scan proceeds from the lowest numbered channel to the highest.
Non-sequential (backward) scanning is only intended to be performed using
remote programming. Unexpected results may occur if a non-sequential scan is
run from the front panel.
For more information, see “Scanning fundamentals — Sequential and non-
sequential scans,” page 7-3.

Scan configuration flowchart
NOTE The instrument is always configured to run a scan. On power-up, each available
channel uses the power-on default setup. For example, for factory power-on
default settings and two Model 7700s installed, the instrument will scan
channels 101 through 220 when the scan is run. See Section 1 for details on
power-on default settings.
