Getting Started
Voltage source
The Model 6487 voltage source can source up to ±505V DC and is used for the ohms
function. See
“Basic connections to DUT,” page 1-4
in
for full details on voltage
source operation.
Analog output
The Model 6487 has an analog output on the rear panel. The ANALOG OUT provides a
scaled, inverting ±2V output. A full-scale reading corresponds to ±2V output. See
for full details on analog output operation.
Digital I/O
The Model 6487's Digital I/O port is a male DB-9 connector located on the rear panel. The
four active-low, digital output lines and one input line are used to control external circuitry. For
detailed connection and usage information, refer to Section 8 of the Model 6487 Reference
Manual.
Display
Readings can be displayed in engineering units or scientific notation. Annunciators indi-
cate various states of operation. See
“Front panel summary,” page 1-7
for a complete list-
ing of display annunciators. The normal display also includes the voltage source value on
the right.
NOTE
Changing the display resolution is not allowed if displaying readings in scien-
tific notation.
The DISP key can be used to turn the display on or off. The Display and Keys Test allows
you to test display digit segments and annunciators, and check the functionality of front
panel keys. These tests are accessed through the MENU.
Status and error messages
Status and error messages are displayed momentarily. During operation and programming,
you will encounter a number of front panel messages. Typical messages are either of status
or error variety, as listed in Appendix B of the Model 6487 Reference Manual.
