To create a remote control sequence or modify the initialization sequence
You have connected and configured external instruments to the R&S SMW as descri-
bed in "To connect instruments to the I/Q analog interface" on page 199.
To create an SCPI sequence or your own initialization sequence and send it to a R&S
SGS connected to the I/Q interface, proceed as follows:
1. On a remote computer, open the notepad or other similar tool.
Write a sequence of SCPI commands.
2. Store the SCPI sequence in a file with file extension *.iec.
3. Use one of the standard file transfer methods to transfer the file to the user direc-
tory /usb/ of the R&S SMW.
See Chapter 10.9, "How to Transfer Files from and to the Instrument",
on page 644.
4. Select "System Config > System Configuration > External RF und I/Q".
5. Select "I/Q OUT 1 > External Instrument > Config"
6. Select "External Instrument Configuration > Remote Control":
a) Select "Mode > Sequence".
b) Select "File" and select the *.iec file form the user directory /usb/.
c) Select "Send Sequence".
7. Alternatively, select "External Instrument Configuration > Initialization Sequence".
a) Select "Remove Initialization Sequence".
b) Select "Initialization Sequence" and select the *.iec file form the user direc-
tory /usb/.

tional instruments for this particular test.
There are two suitable test setups:
●
A test setup with one R&S SMW and six R&S SGT
See "Test setup with R&S SMW and 6xR&S SGT" on page 208
●
A test setup with multiplexed digital output signals
