Model 2790 SourceMeter Switch System Reference Manual
Global settings from the front panel that can be set separately using remote programming
include digits, rate, and filter configuration (except on/off, which can be set separately).

DCV input divider
Using remote programming, you can enable the DCV input divider for the 100mV, 1V, and
10V ranges. When enabled, the input resistance for these DCV ranges are reduced to
10MΩ. See
Multiple channel operation
For 7702 system channel operation, when one measurement channel is closed, the previ-
ous measurement channel opens. With the use of the ROUTe:MULTiple commands, you
gain independent control of all switching module channels, including the relays that con-
nect the input signal to the DMM. See
GPIB setup
The following provides information about GPIB standards, selecting the GPIB, setting the
primary address, and bus connections.
GPIB standards
The GPIB is the IEEE-488 instrumentation data bus with hardware and programming
standards originally adopted by the IEEE (Institute of Electrical and Electronic Engineers)
in 1975. The Model 2790 conforms to these standards:
•
•
The above standards define a syntax for sending data to and from instruments, how an
instrument interprets this data, what registers should exist to record the state of the instru-
ment, and a group of common commands. The Model 2790 also conforms to this standard:
•
This standard defines a command language protocol. It goes one step farther than
IEEE-488.2-1992 and defines a standard set of commands to control every programmable
aspect of an instrument.
Do not confuse function setups with 7702 scan channel setups. For scan chan-
nels, separate settings for digits, rate, and filter configuration can be set from
either the front panel or remote programming. See
channel setup.
