Nodal DOF Commands 5-101
SR780 Network Signal Analyzer
Nodal Degree-of-Freedom Commands
SVNI (?) {i}
The SVNI command determines (queries) whether nodal degree-of-freedom
information will be stored with SR785 data (.78D) files. If this softkey is set to
“on” nodal DOF information will be saved with the files and will be available for
use by external programs which convert SR785 files into formats used by modal
analysis programs. If set to “off” no nodal DOF information will be saved and
the external programs must obtain this information from the user.
RFDR (?) {i}
The RFDR command sets (queries) the reference node direction. The parameter i
specifies the direction according to the following table:

RFNA (?) {s}
The RFNA command sets (queries) the name of the reference node. The name
may be up to 6 characters long.
RFNU (?) {i}
The RFNU command sets (queries) the number of the reference node.
RSDR (?) {i}
The RSDR command sets (queries) the response node direction. The parameter i
specifies the direction according to the following table:
