Output On/Off Synchronization Appendix D

By setting the common delay offset to be greater than or equal to the largest minimum delay offset, you can synchronize the programmed turn-on delays as shown in the following example.

60 ms = common delay offset

Since there will be an additional delay due to the common delay offset, you will need to account for the additional delay time. As shown in the previous example, if you program a common delay of 60 ms and user-programmed delays of 10 ms, 20 ms, 30 ms, and 40 ms for output channels 1 through 4, the actual output delays from the “on” event will be 70 ms, 80 ms, 90 ms, and 100 ms respectively.

Even though this 60 ms delay offset will be seen on all outputs, the additional delay time will not affect most applications because the relative delay times between output module turn-on will still be 10 ms, 20, ms, 30 ms, and 40 ms – the exact values originally specified.

 

If you have previously characterized the minimum turn-on delays of the power

NOTE

modules that you are synchronizing as described in chapter 4 of this guide and

 

 

have incorporated this delay in your application program, you do not need to

 

rewrite your test program. Your application will continue to work as before.

 

 

Procedure

To configure the output turn-on delays:

1. Enable the turn-on synchronization function on the mainframe.

2. Specify the output channels that will be synchronized or coupled.

3. Specify the user-programmed turn-on delay for each output channel that will be synchronized.

4. This step is required if you have power modules with different minimum delay offsets. Specify a common delay offset for all of the synchronized output channels. When the common delay offset completes, the user-programmed turn-on delays will start.

1. Enable the Synchronization Function

Output turn-on synchronization must be enabled on the mainframe.

SCPI Command:

In the front panel menu, select

Output\Couple.

Check the box labeled “Enable”. To disable, uncheck the box.

To enable, send:

OUTP:COUP ON

To disable, send:
