Automation Xpress 5.5 Auto Programmer 5.5.1 Introduction Auto Programmer is a function within Automation Xpress that allows you to remotely program the 2400/2500 using only the buttons and settings within Automation Xpress. Auto Programmer interprets your sequence of actions in Automation Xpress, and converts them into a format usable within a programming application. The general procedure for using Auto Programmer is shown below.

The advantage of this method is simplicity. You only see the file directly related to your actions on GUI. However, you will have to create a project for it in order to compile. This can be achieved easily by looking at the result of second method. Table 46 Generate code to a C/C++ File Step 1.

Giga-tronics 2400/2500 Microwave Synthesizer Series Chapter 6. 6. Status register System Status Register System 6.1 Introduction The Status Register System holds information about the 2400/2500 during remote operation. Several status registers can be queried for specific information about the state of the instrument or the status of events relating to its operation. These registers can be queried directly or can be configured to initiate a service request whenever an expected condition has occurred.

Giga-tronics 2400/2500 Microwave Synthesizer Series 6. Status register System 6.2 Status Byte and Service Request Enable Registers The Status Byte Register is the primary status register. It is the top-level register used to track changes in the state of the 2400/2500. The summary bits of lower-level status registers are set in the Status Byte Register when certain conditions occur that are being monitored by and have been enabled in those lower-level registers.
PAGE 180
6. Status register System Giga-tronics 2400/2500 Microwave Synthesizer Series 6.3 Standard Event Status and Standard Event Status Enable Registers The Standard Event Status Register is one of the lower-level status registers. It monitors certain common instrument status conditions. When a condition occurs that is being monitored by this register, and that condition has been enabled by the Standard Event Status Enable Register, bit 5 is set in the Status Byte Register.

Giga-tronics 2400/2500 Microwave Synthesizer Series 6. Status register System 6.4 Questionable Status Condition and Enable Registers The Questionable Status Register is one of the lower-level status registers. It monitors certain 2400/2500-specific status conditions. When a condition occurs that is being monitored by this register, bit 3 is set in the Status Byte Register. The STATus:QUEStionable:CONDition? query can be used to read the contents of the Questionable Status Register.

Giga-tronics 2400/2500 Microwave Synthesizer Series Chapter 9. 9: LabVIEW Drivers LabVIEW Drivers 9.1 Overview Giga-tronics provides two libraries of drivers that can be used to create LabVIEW applications that work with Giga-tronics 2400 and 2500 series instruments. Most of these drivers directly correlate to functions in the DLL that are included in the CD-ROM or flash drive that ships with 2400 or 2500 series instruments. The remaining drivers perform utility functions.
PAGE 188
9: LabVIEW Drivers Giga-tronics 2400/2500 Microwave Synthesizer Series LabVIEW function call VIs contain the GT2400 DLL functions. The function call VIs have the same name as the associated DLL functions except the prefix is GT2XXX instead of GT2400. Also, all the input, output parameters and the return value of the functions have the same equivalent variable type, and in most cases the variable names are kept the same. The VIs includes ErrorIn and ErrorOut clusters (similar to a structure in C).
