Keithley 7751, 7752, and 7753
Switching Modules
• Card configuration — Provides the simplified schematic of the Keithley 7751,
7752, and 7753 switching modules. Summarizes the individual components of the
modules.
• Setting source output levels — Explains how to set the output levels for the
I-source (7751/7752/7753) and V-source (7751/7753).
• Math — Covers the ohms math functions used to calculate low resistance when
using the I-source of the 7751/7752/7753, and high resistance when using the
V-source and I/V amplifier of the 7751/7753 module.
• Opening and closing channels — Explains how to open and close channels for the
7751, 7752, and 7753 modules.
• Viewing closed channels — Explains how to display closed channels on the
Model 2790.
• Open interlock errors — Explains the errors associated with an open interlock.
• Cable discharge circuit (7751 and 7753) — Explains the cable discharge circuit. It
dissipates voltage at the input channels. This unwanted voltage could ignite the
inflator.
• Connection log — Use to record connection information.
• Using memory patterns — Describes the memory patterns feature, which can be
used to simplify repetitive test procedures.
