Using the Network Analyzer to Control the Test Set
How to Send a Manual Command
How to Send a Manual Command
This procedure assumes the following:
• The instructions in the previous section (“Preparing the Analyzer
to Control the Test Set”) have been performed.
• The command window (C:\Program Files\
National Instruments\NI-488.2\bin\ibic.exe) shown at the
bottom of Figure 3-7 is visible on the analyzer.
Step 1. Select a command from Table 3-2 or Table 3-3.
Step 2. Click in the command window once to ensure that it is active.
Step 3. Verify that the last line of text appearing in the window is the ud0:
prompt with nothing after it.
Step 4. Type ibwrt and then press the <Enter> key.
Step 5. When the prompt enter string: appears, type all
of the following in
exactly the order listed here:
• a double quotation mark (")
• the command selected in Step 1
•a semicolon
• another double quotation mark (")
• the <Enter> key
For example, to connect the Reflection port of the network analyzer to
Test Port #3, type “refl_03;”<Enter>. To connect the Transmission port of
the network analyzer to Test Port #7, type “tran_07;”<Enter>. See Figure
3-6, “User Controller Window.”
Step 6. Look at the PORT CONNECTION display on the test set to verify that
the command was received.
Step 7. If the message on the PORT CONNECTION display is, “ERR: Invalid
Command”, type ibclr<Enter> to clear the bus. Next, repeat Steps 3
through 5.
NOTE
Use the <Up Arrow> key to recall previous commands. This will
decrease typing time and errors.
NOTE
The test set waits until it receives a semicolon before executing any
command. Once the semicolon is received, the test set combines into a
single string all of the characters it has received since the previous
semicolon. The test set then treats the string as a single command.
