HP BASIC Language Programs

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 HP-IB
(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 HP-IB (IEEE-488) address is set to "22" when the meter is shipped
from the factory. The examples in this chapter assume a HP-IB address
of 22. When sending a remote interface command, you append this
address to the HP-IB interface's select code (normally 7). Therefore, with
an address of 22 and a select code of 7, the combination is "722".

HP BASIC / HP-IB 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
60 CLEAR 7
70 ASSIGN @Meter TO 722
80 !
90 OUTPUT @Meter;"*RST"
100 OUTPUT @Meter;"*OPC?"
110 ENTER @Meter;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
170 PRINT Rdg
180 END
