108 Agilent N518xA, E8663B, E44x8C, and E82x7D Signal Generators Programming Guide

Programming Examples

LAN Programming Interface Examples

•error checks

• queries signal generator for ID

• sets frequency on signal generator to 2.5 GHz

• sets power on signal generator to –5 dBm

• gets option letter from argument vector and checks for end of file (EOF)

The following programming examples are available on the signal generator Documentation CD- ROM as

lanio.c and getopt.c.

/***************************************************************************

* $Header: lanio.c 04/24/01

* $Revision: 1.1 $

* $Date: 10/24/01

* PROGRAM NAME: lanio.c

* $Description: Functions to talk to an Agilent signal generator

* via TCP/IP. Uses command-line arguments.

* A TCP/IP connection to port 5025 is established and

* the resultant file descriptor is used to "talk" to the

* instrument using regular socket I/O mechanisms. $

* Examples:

* Query the signal generator frequency:

* lanio xx.xxx.xx.x 'FREQ?'

* Query the signal generator power level:

* lanio xx.xxx.xx.x 'POW?'

* Check for errors (gets one error):

* lanio xx.xxx.xx.x 'syst:err?'

* Send a list of commands from a file, and number them:

* cat scpi_cmds | lanio -n xx.xxx.xx.x

****************************************************************************

* This program compiles and runs under

* - HP-UX 10.20 (UNIX), using HP cc or gcc:

* + cc -Aa -O -o lanio lanio.c

* + gcc -Wall -O -o lanio lanio.c
