You can send SCPI commands in either short or long form. Refer to
Chapter 4 for more information. A long form example is:
CLOSe (@102)
The same command shown without the lower case letters is the short form.
The command then becomes:
CLOS (@102)
Some commands in this manual are shown with brackets ([ ]). These are
implied or optional commands that you do not have to execute. For
example, the
command is an implied command and is shown in this
ROUTe
manual as:
[ROUT:]CLOS (@102)
Thus, to execute these commands, simply enter:
CLOS (@102)
Use the following program example to verify initial Microwave Switch
operation by closing a channel and querying channel closure. The example
first resets the switchbox and then closes channel 02 of a single Microwave
Switch module (card number 1) in the switchbox. The program next queries
the channel closure state. A returned "1" shows that the command to close
the channel has been sent to the switchbox. A returned "0" shows that the
command to close the channel has not been sent to the switchbox.
The computer used in the example is an HP Series 200/300 computer with
HP BASIC as the program language. The computer interfaces to the
mainframe using the Hewlett-Packard Interface Bus (HP-IB).* The HP-IB
interface select code is 7, the HP-IB primary address is 09, and the HP-IB
secondary address is 15. Refer to the HP 75000 Series B Installation and
Getting Started Guide for addressing information.
Example: Reset the switchbox and close channel 02.
10 OUTPUT 70915;"*RST"
20 OUTPUT 70915;"CLOS (@102)"
30 OUTPUT 70915;"CLOS? (@102)"
40 ENTER 70915;Value
50 PRINT Value
60 END
!Resets the module; opens all
channels.
!Close channel 02.
!Query channel 02.
!Enter results into value.
!Display results (should return
"1").
!Terminate program.
