Using IO Interfaces
Using LAN
The MXA receives the LAN0 event and triggers. The MXA's Waiting For Trigger instrument event
transitions low, and a LAN1 output event goes onto the LAN with a falling edge. The MXG takes no
action, since it is configured to trigger only on rising edges. The MXA completes its measurement and
prepares to move on to the next frequency in its list. The MXA's Waiting For Trigger instrument
event transitions high, and a LAN1 output event goes onto the LAN with a rising edge. The MXA
waits for its next trigger.
The two instruments continue to step through their lists until the MXA has completed measurements
at every frequency in its list. Once the final measurement has completed, the OperationComplete
instrument event transitions high, causing the OperationComplete output event to go out onto the
LAN with a rising edge. This event may be caught by a controller to signal the end of the
measurement. The controller may then retrieve the list sweep measurement results from the MXA.
Synchronize a List Sweep Measurement Between an MXA and an MXG using Peer to Peer Messages
1. Disable LXI Output LAN Events on the MXG:
Send the following SCPI command:
:LXI:EVENt:OUTPut:LAN:DISable:ALL
2. Reset the MXG:
Send the following SCPI command:
*RST
3. Choose the MXG's PTP domain:
Send the following SCPI command:
:LXI:CLOCk:PTP:DOMain 0
The parameter may be any integer between 0 to 127.
4. Choose the MXG's LXI domain:
Send the following SCPI command:
:LXI:EVENt:DOMain 0
The parameter may be any integer between 0 to 127.
5. Preset the MXG's list sweep:
Send the following SCPI command:
:LIST:TYPE:LIST:INIT:PRES
6. Sets the MXG to expect a list of frequencies:
Send the following SCPI command:
:FREQ:MODE LIST
7. Sets the MXG to expect a list of powers:
Send the following SCPI command:
:POW:MODE LIST
