Operating the DC Power Analyzer 3

Model N6705A User’s Guide 41

When the Protection function trips:

If an over-voltage, over-current, over-temperature, inhibit signal, a

power-fail condition, or on some modules, a power-limit condition

occurs, the DC Power Analyzer disables the affected output.

To clear the protection function, first remove that condition that

caused the protection fault. Then press the Settings key to access the

Source Settings window. Navigate to and select Protection, then

select Clear All Outputs. This clears the protection function and

returns the output to its previous operating state.

Configure a Turn-On/Turn-Off Sequence

Turn-on and turn-off delays control the turn-on and turn-off

sequencing of the outputs in relation to each other. Press the Settings

key twice to access the Output On/Off Delays window.

Enter the On Delays and Off Delays in milliseconds. Values can

range from 0 milliseconds to 1023 milliseconds in 1-millisecond

increments.

Once output delays have been set, use the All Outputs

key to

start the On delay sequence. Use the All Outputs key to start

the Off delay sequence.

All power modules have an internal delay that applies from the time

that the command to turn on the output is received until the output

actually turns on. This turn on delay is automatically added to the On

delay values that you specify in the Output On/Off Delays window.

Click on Output Coupling to find out what the maximum delay offset

is for the power modules that are installed in the DC Power Analyzer.

This window lets you further customize the operation of the Output

On/Off Delays. Refer to Appendix D for further information.
