Output Grouping - Agilent Technologies N6705 User Manual

Output Grouping

Model N6705 User's Guide
For Agilent N673xB, N674xB, and N677xA power modules, the
power limit function turns the output off after a power limit persists
for about 1 millisecond. A status bit (CP+) will indicate that the
output has been turned off by a power limit condition. To restore the
output, you must first adjust the load so that it draws less power.
Then clear the protection function as previously explained. For these
power modules, it may be preferable to use the current or voltage
setting to limit the output power so as to avoid turning the output off.
If the power limit is left at the maximum rating, these power modules will not
NOTE
enable the power limit protection. The power limit protection will only activate
when the power limit is set to a value less than the maximum rating of the
power module and the output power subsequently exceeds this limit setting.
To specify a power limit, press the Settings key to access the Source
Settings window. Navigate to and select the Advanced button.
Output grouping does not apply to Agilent Models N678xA SMU.
NOTE
Up to four identical outputs can be configured or "grouped" to create
a single output with higher current and power capability. The
following conditions apply for grouped outputs:
Only identical outputs can be grouped. Outputs without identical

model numbers and options will be unavailable for grouping.
Grouped outputs must be connected in parallel (see chapter 2).

On Agilent N676xA power modules, low current measurement

ranges are unavailable. Low current output ranges, are available.
Current-level triggering is unavailable for grouped outputs.

Over-current protection delay has a slightly slower response time

(~10 ms) and slightly less resolution than an ungrouped output.
The power limit setting for Agilent N673xB, N674xB, N677xA,

and N6783A power modules must be set to its maximum value.
