NI- 488.2

The NI- 488.2 library function addresses the GPIB and writes

ibwrt(parameter list)

 

data to the signal generator. The parameter list includes the

 

 

instrument address, session id, and the data to send.

 

 

 

 

SICL

The Agilent SICL function converts data using the format

iprintf (parameter

 

string. The format string specifies how the argument is

list)

 

converted before it is output. The function sends the

 

 

characters in the format string directly to the instrument.

 

 

The parameter list includes the instrument address, data

 

 

buffer to write, and so forth.

 

 

 

 

Enter Function

The HP Basic function ENTER reads formatted data from the signal generator. Other IO libraries use similar functions to read data from the signal generator.

Function Statement

Initialization Command

 

 

 

HP Basic

The function ENTER 719 puts the signal generator into

10 ENTER 719;

 

remote mode, makes it a talker, and assigns data or status

 

 

information to a designated variable.

 

 

 

 

VISA Library

The VISA library uses the viScanf function and an

viScanf (parameter list)

 

associated parameter list to receive data. This function

 

 

receives data from the instrument, formats it using the

 

 

format string, and stores the data in the argument list. The

 

 

parameter list includes the session id and string argument.

 

 

 

 

NI- 488.2

The NI- 488.2 library function addresses the GPIB, reads

ibrd (parameter list)

 

data bytes from the signal generator, and stores the data

 

 

into a specified buffer. The parameter list includes the

 

 

instrument address and session id.

 

 

 

 

SICL

The Agilent SICL function reads formatted data, converts it,

iscanf (parameter list)

 

and stores the results into the argument list. The conversion

 

 

is done using conversion rules for the format string. The

 

 

parameter list includes the instrument address, formatted

 

 

data to read, and so forth.

 

 

 

 

Interface Check using HP Basic and GPIB

This simple program causes the signal generator to perform an instrument reset. The SCPI command *RST places the signal generator into a pre- defined state and the remote annunciator (R) appears on the front panel display.

The following program example is available on the signal generator Documentation CD- ROM as basicex1.txt.
