3. Specify the VXIplug&play driver’s header (.h) file location. a. From the menu bar, select Build | Settings | C/C++ b. Set Category to Preprocessor c. In the field, Additional include directories, specify the path to the hpe6432.h file (for example, c:\vxipnp\winnt\include). Getting Started with Agilent VEE The 32-bit (winnt framework) Agilent Technologies E6432A driver can be used with Agilent VEE 4.0 and above. Agilent VEE 4.0 is a 32-bit version that runs on Windows NT.
Getting Started with LabWindows The 32-bit Agilent Technologies E6432A VXIplug&play driver can be used with LabWindows 5.01 and above. LabWindows 5.01 is a 32-bit version of LabWindows that runs on Windows NT 4.0. To access the functions of the Agilent Technologies E6432A VXIplug&play driver from within LabWindows, select Instrument from the main menu, and select the LOAD... submenu item. In the file selection dialog box that appears, select HPE6432.fp and click on the OPEN button.

} } while (--findCount > 0 && (status = viFindNext(findList, (ViChar)&DeviceName)) == VI_SUCCESS); } viClose(dSession); } Opening an Instrument Session To program the instrument using its VXIplug&play driver, a communication path between the computer/controller and the instrument must be opened.
Opening a Session Using C An example of opening a VXI session is: /* open a VXI session to the instrument at logical address 210 */ #include “visatype.h” #include “hpe6432types.h” #include “hpe6432errors.h” #include “hpe6432.h” ViSession instrumentHandle; ViStatus errStatus; errStatus = HPE6432_init("VXI0::210::INSTR", VI_FALSE, VI_FALSE, &instrumentHandle); if( VI_SUCCESS <> errStatus) { printf("Unable to open instrument\n"); } Opening a Session Using Visual BASIC 6.
Or, the address string can be replaced by a symbolic name such as: Dim resourceName as String resourceName = "VXI0::210::INSTR" Closing an Instrument Session Sessions (instrumentHandle) opened with the HPE6432_init function are closed with the function: HPE6432_close (ViSession instrumentHandle); When no further communication with an instrument is required, the session must be explicitly closed (HPE6432_close). Agilent Technologies VISA does not remove sessions unless they are explicitly closed.
Events and Errors Events and errors within a VXIplug&play program can be detected by polling the instrument’s error queue.

Applications and Example Programs Working with Lists (A Programmer’s Model) Working with Lists (A Programmer’s Model) When using the synthesizer, there are two modes of operation: • Set-Spot Mode means that an external host computer has sent a single frequency or power or both to the synthesizer. • List Mode allows an external host computer to run a pre-loaded list of frequencies or powers or both.
Applications and Example Programs List Modes - Controlled by the featureBits Parameter List Modes - Controlled by the featureBits Parameter A List is defined as one or more points that can be stored in the synthesizer’s List Point Memory. The synthesizer’s list point memory can hold 131,071 points (with a range of 0 to 131,070) and can be broken up into different size lists; although there can be multiple lists stored in list point memory, only one list can be run at a given time.
Applications and Example Programs featureBits Parameter featureBits Parameter HPE6432_RunList(instrumentHandle, startingPoint, numberofPoints, featureBits); When using the HPE6432_RunList() function in any of the list modes, the featureBits parameter controls the features that establish how a list runs. Changing the feature bits to either on or off has the following effect on a list: Decimal Value Bit # Effect on a List 0 With all bits set to 0, the list will run once automatically.
Applications and Example Programs featureBits Parameter Agilent E6432A Microwave Synthesizer User’s Guide 5-9
Applications and Example Programs Trigger Input Mode Trigger Input Mode The trigger input can come from the Trig In on the hardware front panel or one of the eight-shared VXI backplane TTL triggers (TTLTRG0-TTLTRG7). featureBits Mode Description Effect on a List Bit 8 = 0 Automatic Run the list once automatically and do not require a Trig In. Bit 10 = 0 If Automatic is not selected as the Trigger Input Mode value, either Single or Step must be selected; both can not be selected at the same time.
Applications and Example Programs Sync Input Mode Sync Input Mode The trigger input can come from the Sync In on the hardware front panel or one of the eight-shared VXI backplane TTL triggers (TTLTRG0-TTLTRG7). featureBits Mode Description Effect on a List Bit 11 = 0 Automatic Run the list once automatically and do not require a Sync In trigger.
Applications and Example Programs Repeat Mode Repeat Mode featureBits Mode Description Effect on a List Bit 9 = 1 On The synthesizer runs through the list repeatedly until the HPE6432_RunListAbort() function is sent to the synthesizer. The values of the Sync Input Mode, Trigger Input Mode, and Interrupt Mode remain valid. The synthesizer generates an End of List Interrupt after receiving an HPE6432_RunListAbort() function call. Bit 9 = 0 Off Repeat Mode is disabled.
Applications and Example Programs Interrupt Mode Interrupt Mode NOTE To read the interrupt flag status, refer to the HPE6432_GetInterruptFlags() function. When running the synthesizer in list mode, there are seven interrupt causes that can be output on any of the seven VXI backplane interrupt request lines (IRQ1- IRQ7), but only two can be controlled by the user.
Applications and Example Programs Interrupt Mode featureBits Interrupt Description Effect on a List Bit 16 = 1 Settled Interrupt This interrupt occurs simultaneously with the Sync Output Settled Interrupt. As the synthesizer steps through a list, a Settled Interrupt is generated each time a list point is settled (after settling time is complete). Bit 17 = 1 Sync Output Settled Interrupt This interrupt occurs simultaneously with the Settled Interrupt, but is set for a given list point in a list.
Applications and Example Programs Input and Output Triggers Input and Output Triggers Before running a list, input and output triggers must be set up. The synthesizer has two input triggers and two output triggers. The input triggers are only useful when running a list in the synthesizer (list mode), but the output triggers are valid when running a list in the synthesizer or when changing frequency or power or both in set-spot mode.
Applications and Example Programs Trig In Trig In This is an input trigger and its functionality is determined by the mode used during an HPE6432_RunList function. This input trigger can come from the hardware front panel, the VXI backplane, a software function, or it can be disabled. This input trigger can be received at any time after the settling time has occurred. However, an advance will not take place until after the dwell time is completed.
Applications and Example Programs Sync In Sync In This is an input trigger and its functionality is determined by the mode used during an HPE6432_RunList function. This input trigger can come from the hardware front panel, the VXI backplane, a software function, or it can be disabled. This input trigger can only come from one source at a time.
Applications and Example Programs Trig Out Trig Out This is an output trigger and is produced after each new hardware frequency or power level setting has settled; the value of the dwell time controls how long the trigger outputs (Sync Out trigger and Trig Out trigger) are asserted. The Trig Out trigger can be directed to the Trig Out connector on the hardware front panel or one of the eight-shared VXI backplane TTL triggers (TTLTRG0-TTLTRG7) or both at the same time.
Applications and Example Programs Sync Out Sync Out This is an output trigger (that can also be used as a marker) and is asserted during dwell time; the value of the dwell time controls how long the trigger outputs (Sync Out trigger and Trig Out trigger) are asserted. The Sync Out trigger is produced after each point in the list has settled if the point has a Sync Out bit enabled.
Applications and Example Programs Synthesizer Switching Speeds Synthesizer Switching Speeds Synthesizer switching speed is a combination of the assist processor time, switch/blanking time, settling time, and dwell time parameters. NOTE These times are defined as the times that occur once the synthesizer receives a new function from an external host computer.
Applications and Example Programs Synthesizer Switching Speeds Switch/blanking time is established by the following criteria: • 350 us for all frequencies 560 MHz or less • 350 us for all frequencies above 560 MHz with long switch/blanking mode set (long blanking is typically used when external leveling is enabled or when using low ALC bandwidth) • 150 us for all frequencies above 560 MHz with normal switch/blanking mode set • 50 us for all frequencies above 560 MHz with power-only mode set • 20 ms is adde
Applications and Example Programs Synthesizer Switching Speeds Related Topics • When in list mode, the function Write List Points is used to control, on a point by point basis, whether the RF output is on or off during switch/blanking time, and the function Set Long Blanking (On/Off) is used to enable long switch/blanking time.
Applications and Example Programs Synthesizer Switching Speeds Settling Time Settling time is the period of time the synthesizer waits, following the switch/blanking time, before producing a Trig Out trigger or a Sync Out trigger. Settling time is used every time a new frequency or power is set up in the synthesizer. Settling time can be set by an external host computer to different values.
Applications and Example Programs Synthesizer Switching Speeds Some example cases in which the settling time would be extended by the external host computer would be: • when a slow external detector is used; in this case, a longer settling time would be required before the power is settled to within specification • when using Trig Out trigger to trigger a measurement and additional time is required for the measurement system to settle Related Topics HPE6432_SetSettlingTime 5-24 Agilent E6432A Microwave S
Applications and Example Programs Synthesizer Switching Speeds Dwell Time Dwell time is the minimum period of time after the settling time that the synthesizer will remain at its current state. The synthesizer can accept a Trig In trigger during or after the dwell time, but it will not act until after the dwell time is complete. Dwell time can be set by an external host computer to different values. These values of dwell time control how long the trigger outputs are asserted.
Applications and Example Programs Timing Example - Putting It All Together Timing Example - Putting It All Together The above figure shows many of the events that occur while the synthesizer is running a list. In this example, trigger inputs and outputs are connected using the hardware front panel connectors. The list is set to run with the following values: Sync Input Mode = Automatic, Trigger Input Mode = Stepped, Repeat Mode = On, and Interrupt Mode = Off.
