driver->Parameters->Voltage = 1.2; driver->Parameters->HighLimit = 5; driver->Parameters->LowLimit = 0.0; driver->Parameters->RampUpTime = 1; driver->Parameters->DwellUnit = HypotMAXTimeUnitEnum::HypotMAXTimeUnitSecond; driver->Parameters->DwellTime = 3; driver->Parameters->RampDownTime = 0.5; driver->Parameters->Frequency = HypotMAXFrequencyEnum::HypotMAXFrequency50Hz; configuration only for ACW (7705,7715) driver->Parameters->ArcDetectEnable = true; driver->Parameters->ArcSense = 9; driver->Parameters->Connect = false;

//This

For the HypotMAX, all of the test parameters are within a “memory”. There are fixed 50 memories available and a configuration named “Connect” to determine whether to go to next memory or end the test. In the above example, the “connect” configuration is enabled in memory #1 ,so the HypotMAX will continue to the memory #2.
Please be noted that the “Frequency” parameter is for AC Withstand which was provided by 7705 and 7715. Instead, there are “Ramp-HI” and “ChargeLo” available in DC Withstand test of 7710 and 7720.

3.3 Load file and start a test
//Output driver->Parameters->LoadMemory(1); driver->Execution->Execute();
Before running output, you have to select a memory to be load by using driver->Parameters>LoadMemory(1). And then invoke driver->Execution->Execute() method to start a test.

3.4 Measure during test
bool lastOpcStatus = false; while (true) {
std::cout << driver->Execution->ReadTestDisplayRaw() << std::endl; driver->System->WriteString(“*OPC?n”); std::string opcStatus = driver->System->ReadString(); if (opcStatus.find(“1”) != std::string::npos && lastOpcStatus)
break; lastOpcStatus = opcStatus.find(“1”) != std::string::npos; Sleep(100); }
This while loop would run with the condition of state is testing. Using the methods of
Execution->ReadTestDisplayRaw() could let you read the immediate readings.

3.5 Close the session
driver->Execution->Abort(); driver->Close(); std::cout << “Done – Press Enter to Exit” << std::endl; std::cin.get();
Close() would close the I/O session to the instrument. 4 Completed example

Development
1 Install the Comtypes library pip install comtypes
In order to call an external com DLL in Python, you will need comtypes library installed.
2 Create a Python file 2.1 Open any IDE of Python and create a new Python file.
3 Import Libraries 3.1 Import the cometypes library and HypotMAX_64.dll
import time import comtypes import comtypes.client as cc # Import the IVI-COM DLL cc.GetModule(‘HypotMAX_64.dll’) from comtypes.gen import HypotMAXLib
4 Start programming 4.1 Create an object of the driver and use the initialize method to build up the connection.
driver = cc.CreateObject(‘HypotMAX.HypotMAX’, interface=HypotMAXLib.IHypotMAX)

Initialize Driver and make connection driver.Initialize(‘ASRL3::INSTR’,

True, False, ‘DriverSetup=BaudRate=9600’)
For more detail for the parameters of the Initialize() method, please refer to the help document, HypotMAX.chm located at “IVI FoundationIVIDriversHypotMAX”. The first parameter ResourceName is a string type and indicates the interfaces type and address of the connection. The resource name,”ASRL3::INSTR”, represents a serial port with address 3. For example, a GPIB connection could be “GPIB0::8::INSTR”. For TCP/IP connection, it will be in the format of “TCPIP0::192.168.0.1::10001::SOCKET”. The 10001 is the TCP/IP connection port of HypotMAX. If you use serial port to connect to device, please follow the above example, “DriverSetup=BaudRate=9600”, to setup the baud rate. There are other parameters for the option of the Initialize() method, please refer to the HypotMAX.chm for more detail. For example, “QueryInstrStatus=true” makes the session automatically query the error status for each command was sent.

5. Getting Started with LabVIEW
Introduction
This chapter describes the procedures of using the IVI-COM driver of IKONIX Group by LabVIEW programming language. In this exercise, the programmer could learn how to import the driver and complete a short program controlling the device step-by step.
Even though the programmers could control the device by IVI Driver. For the LabVIEW programmer, we suggest that using LabVIEW plug & play driver would be easier for your programming and debugging. The LabVIEW drivers from IKONIX Group are all made up with commands directly, so you could clearly check how the commands were sent to instruments.

1 Open a new vi. 2 Import the DLL component.

Development

Open the Function Palette by right-clicking on the block diagram. Then select Connectivity -> ActiveX. Select or drop the Automation Open function on the block diagram. 3 Right-clicking on the Automation Open and select Select ActiveX Class -> Browse will open a window for choosing the DLL. 4 Select the Browse button and select the file HypotMAX_64.dll located at <Program Files>IVI FoundationIVIBin. The IVI HypotMAX Type Library would be added into the Type Libraries drop down menu. 5 Select IHypotMAX and then click OK to complete creating an object of HypotMAX driver instance.
The Labview will automatically generate an Automation refnum of HypotMAXLib.IHypotMAX control and connect to the Automation Open function.

6 Create an Invoke Node function and connect the reference to the output of Automation Refnum and then click on the Method and select Initialize to initialize the connection with device.
For more detail for the parameters of the Initialize method, please refer to the help document, HypotMAX.chm located at “IVI FoundationIVIDriversHypotMAX”. The first parameter ResourceName is a string type and indicates the interfaces type and address of the connection. The resource name, “ASRL3::INSTR”, represents a serial port with address 3. For example, a GPIB connection could be “GPIB0::8::INSTR”. For TCP/IP connection, it will be in the format of “TCPIP0::192.168.0.1::10001::SOCKET”. The 10001 is the TCP/IP connection port of HypotMAX. If you use serial port to connect to device, please follow the above example, “DriverSetup=BaudRate=9600”, to setup the baud rate. There are other parameters for the option of the Initialize() method, please refer to the HypotMAX.chm for more detail.

6.1 Create file and setup test
Use the Property Node to get reference of the sub-system of IHypotMAX class. For example, Parameters is one of the sub-class of IHypotMAX, and then we could use the LoadMemory method under Parameters to switch the memories in the device. For HypotMAX, there are constant 50 memories inside the device. Before set up the configurations, please be noted that you have to switch to the corresponding memory. There is a configuration, Connect, to determine whether to link to next memory. Taking a 5-steps test as an example, the Connect of the first step to forth step need to be set with True and the fifth memory needs to be set with False.

6.2 Start a test and measure
Before running output, you have to select a memory to load. And then invoke Execute method to start a test under Execution class. The Execution class is one property of the IHypotMAX class. This for loop would run with polling the state and meters. Using the methods of ReadTestDispalyRaw could let you read the immediate readings. ReadTestDispalyRaw is one method of IHypotMAX.Execution. There is another commands querying states of the device, polling “*OPC?” could get the running status. Please be noted that the status between step and step might be OFF for a shot moment. To avoid reading wrong status, we use shift register comparing the status.

6.3 Close the session
Close method in IHypotMAX class would close the I/O session to the instrument. Also, all of the references should be closed using the Close Reference function. 7 Completed example
The completed example with the state machine design pattern for your reference which are located at the path of IVI FoundationIVIDriversHypotMAXExamples, including C#, C++ and Python as well. However, we suggest that using LabVIEW plug & play driver would be easier for LabVIEW developers. If you need a LabVIEW driver, please download it from the website of Associated Research or contact the vendor.
