Queries Using HP Basic and GPIB
This example demonstrates signal generator query commands. The signal generator can be queried for
conditions and setup parameters. Query commands are identified by the question mark as in the
identify command *IDN? basicex3.txt performs the following functions:
• clears the signal generator
• queries the signal generator’s settings
The following program example is available on the signal generator Documentation CD- ROM as
basicex3.txt
.

120 DIM A$[10],C$[100],D$[10] ! Declares variables to hold string response data
130 INTEGER B ! Declares variable to hold integer response data
140 Sig_gen=719 ! Declares variable to hold signal generator address
150 LOCAL Sig_gen ! Puts signal generator in Local mode
160 CLEAR Sig_gen ! Resets parser and clears any pending output
170 CLEAR SCREEN ! Clears the controller’s display
180 OUTPUT Sig_gen;"*RST" ! Puts signal generator into a defined state
190 OUTPUT Sig_gen;"FREQ:CW?" ! Querys the signal generator CW frequency setting
200 ENTER Sig_gen;F ! Enter the CW frequency setting
210 ! Print frequency setting to the controller display
