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

m.mm= Mainframe revision number

b.bb= Boot code revision number

f.ff= Front-panel revision number

d.dd= Internal DMM revision number

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.
