Interrupt Function
This feature is available for the U2651A and U2652A. There are two interrupt
sources for the interrupt function, which are bit 301 and bit 302 located at input
channel 101. They are actually physically sharing the same bit with bit 101.0 and
bit 101.1. See “Connector Pins Configuration for U2651A” on page 33 and
“Connector Pins Configuration for U2652A” on page 35 for the location of bit 301
and bit 302.
To use this feature, the user has to enable the interrupt first by selecting the
triggering source (i.e. bit 301 or bit 302). For example, the following SCPI
command is used to set bit 301 as the triggering source.
SENS:DIG:INT:ENAB ON, (@301)
When the logic level of bit 301 changes from “0” to “1” (i.e. an interrupt has
occurred), the bit 0 of Event Register (EV) is set to “1”. See Figure 3-5 . To alert the
Status Byte Register that an interrupt has occurred, the user has to enable the
Enable Register (EN) at the Interrupt Operation Register using the following SCPI
command:
STAT:INT:ENAB 1
Figure 3-5 Enabling the Interrupt Operation Register will allow it to send a
signal, “1” to the Status Byte Register when either the logic level
for bit 301 or bit 302 changes from “0” to “1”.
