:INTerrupt:PRIority[n] DIAGnostic:INTerrupt:PRIority[n] [< level>] gives a priority level to the VXI
interrupt line specified by [n] in …PRIority[n].

level numeric 1 through 7| MIN| MAX| DEF none
Comments • The priority of an interrupt line determines which line will be
acknowledged first in the event that more than one line is interrupting.
• For level, lower values have lower priority (level 1 is lower priority than
level 2).
• No parameter, or DEF (default) sets priority to 1.
•…PRIority1 through …PRIority7 specify the VXI interrupt lines 1
through 7.
• Sending PRIority without an [n] value specifies VXI interrupt line 1.
• This command has no effect if only one interrupt is to be set up.
• Related Commands: DIAG:INT:ACT, DIAG:INT:SETup[n],
DIAG:INT:RESP?
Example Setup, set a priority, and wait for VXI interrupt response on line 2.
DIAG:INT:PRI2 5 handle interrupt on line 2
DIAG:INT:PRI2 5 set priority to 5 on line 2
