System-Related Operations<br />

Features and Functions 3<br />

This section gives information on system- related topics such as instrument<br />

state storage, error conditions, self- test, and front- panel display control.<br />

This information is not directly related to making measurements but is an<br />

important part of operating the instrument.<br />

Firmware Revision<br />

The mainframe, the internal DMM, and each of the plug- in modules has its<br />

own microprocessor. You can query each to determine which version of<br />

firmware is installed. For the mainframe, three firmware revision numbers<br />

are returned: mainframe revision, boot code revision, and front- panel<br />

revision. For the internal DMM and all plug- in modules, one firmware<br />

revision number is returned.<br />

Front Panel Operation: Utility > FIRMWARE > REVISIONS<br />

Use the knob to scroll through the revision numbers for the mainframe,<br />

internal DMM, and each installed module.<br />

Remote Interface Operation: Use the following command to read the<br />

mainframe firmware revision numbers (be sure to dimension a string<br />

variable with at least 72 characters).<br />

*IDN?<br />

The above command returns a string in the form:<br />

AGILENT TECHNOLOGIES,<strong>34980A</strong>,,m.mm–b.bb–f.ff–d.dd <br />

m.mm<br />

b.bb<br />

f.ff<br />

d.dd<br />

= Mainframe revision number<br />

= Boot code revision number<br />

= Front-panel revision number<br />

= Internal DMM revision number<br />

Use the following command to read the firmware revision number of the<br />

module in the specified slot (be sure to dimension a string variable with<br />

at least 73 characters).<br />

SYSTem:CTYPe? <br />

This command returns a string in the form:<br />

AGILENT TECHNOLOGIES,,,<br />

A 10- digit string is returned for the Serial Number field. The Firmware<br />

Revision has the form R.RR and indicates the revision of firmware<br />

currently in use on the specified module.<br />
