3 Operating the DC Power Analyzer
44 Model N6705A User’s Guide
On Agilent N675xA, and N676xA power modules, the power limit
function limits the output power at its programmed setting. A status
bit (CP+) will indicate that the output is in power limit mode. When
the power drawn by the load is reduced below the power limit
setting, the output returns to normal operation. Note that these
power modules contain an active down-programmer circuit, which is
limited to about 7 W continuous power. A status bit (CP-) will
indicate that the output has reached the negative limit.
On Agilent N673xB, N674xB, and N677xA power modules, the
power limit function turns the output off after a power limit
condition persists for about 1 millisecond. A status bit (CP+) will
indicate that the output has been turned off because of a power limit
condition. To restore the output, you must first adjust the load so
that it draws less power. Then you must clear the protection function
as previously explained. On these models, it may be preferable to use
the current or voltage setting to limit the output power so as to avoid
turning the output off.
NOTE
When Agilent N673xB, N674xB, and N677xA power modules are grouped or
paralleled, you must set their power limit setting to its maximum value.
To program the power limit function, press the Settings key. Scroll
down and select Power Limit. Enter the power limit for the specified
output in Watts.
Turn-on Preference
NOTE
Only applies to Agilent N676xA power modules.
This function sets the preferred mode for output on or output off
transitions. It allows output state transitions to be optimized for
either constant voltage or constant current operation. Selecting
Voltage minimizes output on/off voltage overshoots in constant
voltage operation. Selecting Current minimizes output on/off current
overshoots in constant current operation.
To program the Turn-on Preference, press the Settings key. Scroll
down and select the Turn-on Pref drop-down list. Select either
Voltage or Current priority as the turn-on preference.
