Manual Revisions
This manual was written for dc power supplies that have the same manufacturing dates (the first four digits) as those listed on the title page and whose unique identification number (the last four digits) are equal to or higher than those listed in the title page.
NOTE: 1) If the first four digits of the serial number of your unit are higher than those shown in the title page, your unit was made after the publication of this manual and may have hardware or firmware differences not covered in this manual. If they are significant to the operation and/or servicing of the dc power supply, those differences are documented in one or more Manual Change sheets included with this manual.
2)If the first four digits of the serial number of your unit are lower than those shown on the title page, your unit was made before the publication of this manual and may be different from that described here. Such differences, if any, will be covered in a backdating section in Chapter 6.
Firmware Revisions
You can obtain the firmware revision number by either reading the integrated circuit label, or query the dc power supply using the GPIB *IDN?' query command (See Chapter 3, ROM Upgrade).
Electrostatic Discharge
CAUTION: The dc power supply has components that can be damaged by ESD (electrostatic discharge). Failure to observe standard antistatic practices can result in serious degradation of performance, even when an actual failure does not occur.
When working on the dc power supply, observe all standard, antistatic work practices. These include, but are not limited to:
aWorking at a
aUsing a conductive wrist strap, such as Agilent P/N
aGrounding all metal equipment at the station to a single common ground.
aConnecting
components have power applied to them.
aRemoving power from the dc power supply before removing or installing printed circuit boards.
