Table 10-5
LXI trigger edge detection
Set the LAN trigger mode to configure edge detection method in incoming LXI trigger packets. The
mode selected also determines the hardware value in outgoing LXI trigger packets.
Table 10-6 lists
the LAN trigger modes.
Table 10-6
LAN trigger modes
The following is an example of how to configure the LAN trigger mode:
-- Set LAN trigger 2 to have falling-edge mode.
lan.trigger[2].mode = lan.TRIG_FALLING
Understanding LXI trigger event designations
LAN trigger objects generate LXI trigger events. The LXI standard designates trigger events as
LAN0 to LAN7 (zero based). In the command table, the LXI trigger events can be accessed using
lan.trigger[1] through lan.trigger[8]. lan.trigger[1] corresponds to LXI trigger
event LAN0 and lan.trigger[8] corresponds to LXI trigger event LAN7.
Generating LXI trigger packets
The Series 2600A can be configured to output a LXI trigger packet to other LXI instruments. In
order to generate LXI trigger packets, you must first call the lan.trigger[N].connect
function. Select the event that triggers the outgoing LXI trigger packet by assigning the specific
event ID to the LAN stimulus input.
