Appendix D Output On/Off Synchronization

2. Specify which Output Channels will be Synchronized
Select the output channels that will be synchronized.
Front Panel:
In the front panel menu, select
Output\Sequence\Couple.
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:
For channels 1, 2, 3, and 4, select
Output\Sequence\Delay.
Specify the Turn-on delay for each
channel in seconds; then press
Select.
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:
In the front panel menu, select
Output\Sequence\Couple.
The Max delay offset for this frame
field displays the delay offset of the
slowest power module in the frame.
Enter the delay offset value of the
slowest power module in the Delay
offset field in milliseconds; then press
Select.
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.
SCPI Command:
To specify a channel or channels:
OUTP:COUP:CHAN 1,2,3,4
SCPI Command:
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)
SCPI Command:
To query the delay offset of the
slowest power module in the
mainframe (the maximum delay
offset) in seconds:
OUTP:COUP:MAX:DOFF?
To specify the common delay offset
for the mainframe in seconds:
OUTP:COUP:DOFF .051
