285User Manual 1178.3711.02 ─ 08
You find the remote control command sets supported by the R&S SMB100B in a selec-
tion list.
The selected instrument also defines the identification string that is retrieved with query
*IDN?. If necessary, use the parameter Mode and IDN String to change this string.
As any other parameter, the remote control command set can also be changed
remotely by the command :SYSTem:LANGuage.
While working in an emulation mode, the R&S SMB100B specific command set is dis-
abled and the SCPI command :SYSTem:LANGuage is discarded.
To return to the SCPI command set of the R&S SMB100B, use the appropriate com-
mand of the selected command set.
If for example an HP generator is emulated, the HP command EX returns to the instru-
ment-specific GPIB command set.
About health and utilization monitoring system (HUMS)
The R&S SMB100B comes with a health and utilization monitoring system (HUMS)
providing information about the R&S SMB100B. Aim is to increase the overall utiliza-
tion, to avoid downtime and to increase the overall security level of a fleet of instru-
ments.
HUMS provides, for example, information about:
●
Instrument identification, hardware components, software packages, licenses
●
Usage of remote control, usage via keyboard / mouse, usage of test applications
●
Hardware utilization and status, including S.M.A.R.T. data of the system drive
●
User-defined static information, for example, an inventory code
Interfaces and protocols
The HUMS installation on the R&S SMB100B includes an SNMP agent and a REST
service with HTTP endpoints. So you can access the health and usage information via
LAN, using the SNMP protocol or the REST protocol. Accessing the data does not
interfere with remote control via SCPI commands or with measurement execution.
Reference information for both protocols is available on the R&S SMB100B at the
address http://<instrument>/api/hums/v1/documents?name=<interface>.
For <instrument>, enter the hostname (e.g. SMB100B-102030) or the IP address (e.g.
10.121.0.34) of your instrument, as for access to the GUI.
For <interface> = snmp, you get a .zip file containing the MIB files for SNMP. For
<interface> = rest, you get a web page with the OpenAPI specification of the REST
API.
Address example: http://SMB100B-102030/api/hums/v1/documents?name=snmp.
The following table lists the REST endpoints and the SNMP MIB file names.
