Buy HP33120A HP33120A synthesized function generator.

! High prices! Recycling HP33120A, the HP 33120A synthesized function generator. 

 HP33120A, Hewlett-Packard Company production of a high-performance 15MHz synthesized function generator, it has a built-in arbitrary waveform. 
 Equipped with GPIB and RS232 interface, it can communication with computer or directly from the computer to its remote control. 
 Control instructions in full compliance with the standard command of SCPI programmable instrument. 
 First, the the HP33120A control software should support the control of all the measurement functions of the instrument, which is connected to the system to normal, 
 Remote users completely without direct manipulation of instruments measuring tasks can be completed; Secondly, the control software should provide a graphical waveform editing tools, 
 Allows the user operating the mouse to draw and edit arbitrary waveform for output; Finally, the software support for instrument network share. 
 HP33120A configuration of a standard GPIB interface, and all of its measurement capabilities and instrument internal management tasks are available through SCPI commands 
 Computer control. Of course, the instrument can not directly receive SCPI command string, you must first establish between the computer and instrument GPIB interface 
 Session channels, this task is to achieve by standard VISAI / library functions. The HP33120A control software including instrument initialization and tube 
 Management modules, standard and special waveform, select settings and output modules, arbitrary waveform drawing, editing, storage and output modules, waveform modulation selection, 
 Settings and output modules, this paper introduces the instrument initialization and management and arbitrary waveform drawing, editing, storage and output of the two modules 
 And programming. 
 2.1 Instrument initialization and management 
 HP33120A instrument initialization and management interface shown in Figure 1. The startup parameters of the instrument primary address refers Instruments GPIB interface address 
 This address can be changed in two ways: First, set the I / O configuration software via the GPIB interface cassette; 
 HP33120A instrument panel, select I / OMENU in HPIB the ADDR change its parameters. 
 The HP33120A startup will display information "the ADDR?? 1-2 seconds, the number"?? "The address of the instrument. 
 The user should be the number correctly fill in the dialog box of the instrument primary address, the wrong address will enable all of the control command is invalid. 
 If the program initialization can not be successful, first check the startup parameters correctly match, followed by the inspection equipment is turned on. 
 GPIB interface card configuration and connection is working properly. The initialization routine also provides three checkboxes 
 Allows the user to select the appropriate initialization. Authentication by sending a common command * IDN? "To read the instrument identification string. 
 Determine whether the the HP33120A instruments; "reset" the instrument back to its default initial state by sending a common command * the PST; 
 Self-test through to send the command "* the TST?" Instrument to run self-tests. To error, able to accurately determine the error 
 Reason, the control program specifically set up an error message. If a command error occurs, the main program will send an error inquiry command 
 SYSTem: ERROR? "Read the instrument error message, pointing out the error code, error sources and error information about the. 
 Normal instrument initialization is complete, the user can click on the function panel function buttons to enter a new user interface.
