Basic Programming Examples
The following examples illustrate the basic approach to controlling the Test Set
through the GPIB. The punctuation and command syntax used for these examples
is given in
The bus address 714 used in the following BASIC language examples uses an
GPIB interface at select code 7, and a Test Set GPIB address of 14. All examples
use an external controller.
To Change a Field's Setting
1. Access the screen containing the field whose setting is to be changed by using the DISP
2. Make the desired setting using the proper command syntax (refer to
The following example makes several instrument setting changes:
OUTPUT 714;"DISP CCNT"!Displays the CDMA CALL CONTROL screen.
OUTPUT 714;"CDMA:CELL:ASEC -100"!Sets Sector A Power to -100 dBm/BW.
OUTPUT 714;"RFG:OUTP 'DUPL'"!Sets the Output Port to Duplex.
To Read a Field's Setting
1. Access the screen containing the field whose setting is to be read using the DISPlay
2. Use the query form of the syntax for that field to place the setting's value into the Test
3. Enter the value into the correct variable type within the program's context.
The following example reads the current power measurement selection (Average
Power or Channel Power).
10 OUTPUT 714;"DISP CTXT" !Displays the CDMA CELLULAR MOBILE TRANS-
MITTER TEST screen.
20 OUTPUT 714;"CDMA:TX:POW:MEAS?" !Queries the Average Power/Channel
Power field.
30 ENTER 714;Pow$ !Enters the returned value into a string variable
40 PRINT "The power measurement currently selected is ",Pow$
