System-Related Operations
This section gives information on system-related topics such as instrument
state storage, error conditions, self- test, and front- panel display control.
This information is not directly related to making measurements but is an
important part of operating the instrument.
Firmware Revision
The mainframe, the internal DMM, and each of the plug-in modules has its
own microprocessor. You can query each to determine which version of
firmware is installed. For the mainframe, three firmware revision numbers
are returned: mainframe revision, boot code revision, and front-panel
revision. For the internal DMM and all plug-in modules, one firmware
revision number is returned.
Front Panel Operation: Utility > FIRMWARE > REVISIONS
Use the knob to scroll through the revision numbers for the mainframe,
internal DMM, and each installed module.
Remote Interface Operation: Use the following command to read the
mainframe firmware revision numbers (be sure to dimension a string
variable with at least 72 characters).
*IDN?
The above command returns a string in the form:
AGILENT TECHNOLOGIES,34980A,<Serial Number>,m.mm–b.bb–f.ff–d.dd
Use the following command to read the firmware revision number of the
module in the specified slot (be sure to dimension a string variable with
at least 73 characters).
SYSTem:CTYPe? <slot>
This command returns a string in the form:
AGILENT TECHNOLOGIES,<Model Number>,<Serial Number>,<Firmware Rev>
“0” is always returned for the Serial Number field. The Firmware Revision
has the form R.RR and indicates the revision of firmware currently in use
on the specified module.
