Selecting
the Line
Terminator
Data is delimited on the GPIB by either the carriage
return (CR) ASCII character or both the carriage re-
turn and line feed (CR/LF) ASCII characters. Which
character is used depends upon the requirements of
the system controller. Most modern controllers can
use either CR or CR/LF, while many older control-
lers require one or the other. Consult the controller’s
manual for its particular requirements.
From the Configure GPIB Menu display, you can se-
lect which GPIB terminator to use by pressing the
menu soft-key
Line Term
. This menu soft-key tog-
gles the GPIB terminator between CR and CR/LF.
The current selection appears on the display.
Selecting the
Interface
Language
Series 680XXB Synthesized CW Generators can be
remotely operated via the GPIB using one of two ex-
ternal interface languages—Native or SCPI (Option
19). The Native interface language uses a set of
680XXB GPIB Product Specific commands to control
the instrument; the SCPI interface language uses a
set of the Standard Commands for Programmable In-
struments commands to control the unit.
The Configure GPIB Menu has an additional menu
display. For instruments with Option 19, selection of
which external interface language is to be used is
made from this additional menu. From the Config-
ure GPIB Menu display, you can access the addi-
tional menu by pressing
More
. The additional Con-
figure GPIB Menu (below) is displayed.
Press
Native/SCPI
to select the external interface
language to be used. This menu soft-key toggles the
language selection between Native and SCPI. The
current selection appears on the display.
