HP BASIC Language Programs
All of the HP BASIC examples in this chapter were developed and tested on an HP
9000 Series 300 controller. Each device on the GPIB (IEEE-488) interface must
have a unique address. You can set the meter’s address to any value between 0
and 30. The current address is momentarily displayed on the front panel when you
turn on the meter.
The GPIB (IEEE-488) address is set to “22” when the meter is shipped from the
factory. The examples in this chapter assume a GPIB address of 22. When sending
a remote interface command, you append this address to the GPIB interface’s
select code (normally 7). Therefore, with an address of 22 and a select code of 7,
the combination is “722”.
HP BASIC/GPIB Program Example 1
This example demonstrates the general sequence of programming and the use of
the MEASure? command to set and obtain a 4-wire Ohms measurement.
10 !
20 ! This program configures the meter for a 4-wire ohms measurement on
30 ! Channel 1 using the MEAS command.
40 !
50 REAL Value,Rdg ! Dimension real variables
60 CLEAR 7 ! Clear interface - send "device clear"
70 ASSIGN @Meter TO 722 ! Assign I/O path to address 722
80 !
90 OUTPUT @Meter;"*RST" ! Reset the meter
100 OUTPUT @Meter;"*OPC?" ! Send "1" to output buffer when reset complete
110 ENTER @Meter;Value ! Enter value
120 !
130 ! Select 4-wire ohms on the 10 ohm range with the least resolution;
140 !
150 OUTPUT @Meter;"MEAS:FRES? 10,MAX"
160 ENTER @Meter;Rdg ! Enter reading
170 PRINT Rdg ! Print reading
180 END
