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 />
