Agilent Technologies N6700 manual Specify which Output Channels will be Synchronized

Appendix D Output On/Off Synchronization

2. Specify which Output Channels will be Synchronized

Select the output channels that will be synchronized.

Front Panel:	SCPI Command:
In the front panel menu, select	To specify a channel or channels:
Output\Couple.	OUTP:COUP:CHAN 1,2,3,4
Check which channels will be coupled.
To remove a channel, uncheck the box.

3. Specify the Turn-On Delays for each Output Channel

Turn-on delays can be specified for all coupled output channels. Any delay sequence can be implemented. There are no restrictions on what the sequence is or what channel comes up first.

Front Panel: SCPI Command:

For channels 1, 2, 3, and 4, select

Output\Delay.

Specify the Turn-on delay for each channel in seconds; then press Select.

Program a turn-on delays for channels

1 through 4:

OUTP:DEL:RISE .01,(@1) OUTP:DEL:RISe .02,(@2) OUTP:DEL:RISE .03,(@3) OUTP:DEL:RISE .04,(@4)

4. Specify the Common Delay Offset

Specifying a common delay offset assures that the user-programmed turn-on delays will be synchronized to start at the completion of the common delay offset. Select the delay offset of the slowest power module in the mainframe and use that as the common delay offset.

Front Panel: SCPI Command:

In the front panel menu, select

Output\Couple.

In the Delay offset field, enter the delay offset value of the slowest power module in the mainframe in milliseconds; then press Select. The Max delay offset for this frame field displays the delay offset of the slowest power module in the frame.

To specify the common delay offset for the mainframe in seconds:

OUTP:COUP:DOFF .051

To return the delay offset of the slowest power module in the mainframe (the maximum delay offset) in seconds:

OUTP:COUP:MAX:DOFF?

Note that you can program a common delay that is longer than the maximum delay offset of the mainframe. You may choose a longer value to make your program flexible for future configurations that may have power modules with longer delay offsets. However, if you program a value that is shorter than the maximum delay offset, you may experience improper synchronization across all outputs.

	There is no need to specify a delay offset when outputs turn off. Outputs start
NOTE
	executing their turn-off delays as soon as an output Off command is received.
