Measurement Synchronization with LXI-B
Setting Up and Executing a List Sweep Measurement
7. Tell the MXG to
expect a list of powers.
:POW:MODE LIST
This command is sent
to the MXG.
8. Tell the MXG how
the lists will be entered.
:LIST:TYPE LIST
An arbitrary list will be
used instead of range
and step size
arguments.
9. Send the MXG a list
of frequencies
:LIST:FREQ 100 MHz, 200 MHz, 300
MHz, 400 MHz, 500 MHz
This command is sent
to the MXG.
The MXG will put out
signals at these
frequencies and in this
order.
10. Send the MXG a list
of powers
:LIST:POW 0 dBm, -1 dBm, -2 dBm,
-3 dBm, -4 dBm
This command is sent
to the MXG.
The MXG will put out
signals at these powers
and in this order.
11. Turn off signal
modulation.
:OUTP:MOD OFF
This command is sent
to the MXG.
12. Turn signal output
on.
:OUTP ON
This command is sent
to the MXG.
13. Configure the
MXG’s LXI Output
LAN Event
LXI:EVENt:OUTPut:LAN:DRIVe
“LAN0”,NORMal
LXI:EVENt:OUTPut:LAN:SLOPe
“LAN0”,POS
LXI:EVENt:OUTPut:LAN:SOURce
“LAN0”,”WaitingForTrigger”
These commands are
sent to the MXG.
Together, these
commands will cause
the MXG to send a
“LAN0” peer to peer
message every time the
WaitingForTrigger
instrument event
changes state.
14. Set the MXG’s
trigger source.
LIST:TRIG:SOUR LAN
This command is sent
to the MXG.
15. Enable the MXG’s
LXI LAN Event trigger
TRIG:LXI:LAN:ENABled “LAN1”,1
This command is sent
to the MXG.
The MXG will step
through its list when it
receives a “LAN1” peer
to peer message.
