Output Tab help

Either Voltage or Current Source Mode can be selected by toggle switch

Voltage Source Mode  Selects voltage priority mode.

  • Range  Selects 6-V or 13-V output range.

  • Bandwidth  Selects one of four source bandwidths. To avoid output oscillation, ringing, overshoots, and poor transient response, refer to the following table for the correct bandwidth setting. The Low setting is the most stable, but has the slowest response. The High settings provide faster response times for the specified load capacitances.

  • +I Clamp  Sets the positive current limit. When the output source level exceeds this, the trace is clipped.

  • -I Clamp  Sets the negative current limit. When the output source level exceeds this, the trace is clipped.

Current Source Mode  Selects current priority mode.

  • Range  Selects 1-mA or 3-A output range .

  • V Clamp  Specifies the voltage limit. When the output source level exceeds this, the trace is clipped.

Protection Status  Show the current output status: Source On or Off

Reset Protection  Resets a protection trip, after you clear the cause of the trip

Refresh Status  Update the latest protection status.

Enable oscillation protection  Enables or disables protection against oscillation of the output. This setting is used for all channels.

Overvoltage protection level  Specifies the value at which overvoltage protection trips

Lock output relay closed for all channels  When this box is checked, the relay in SMU is always closed even output is enabled or disabled.  This function avoids its mechanical relay from abrasion. This setting is used for all channels.

Enable Source Sequence:

  • Enable: At the beginning of the channel, it will turn on SMU outputs in order from lowest number to highest number, waiting the "Source Settling Time" between each SMU. At the end of the channel, it will turn off SMU outputs in order from highest number to lowest number, waiting the Source Settling time between each SMU.

  • Disable: the SMUs will be turned on and off in the same order as described above, but there will be no settling time between the SMUs.  However, the "source settling time" will be used to calculate the time to wait at the beginning of sweep after all SMUs are turned On and at the end of sweep after all SMUs are turned Off.

  • This is set per-channel and the same for all SMUs.

Settling time:

  • When the source voltage or source current is enabled/disabled/changed at the beginning or end of the sweep,

    • The VNA will check to see when it has settled, tThen it will wait the additional time indicated by the "Source Settling Time" before continuing with the measurement.  

    • Note that if the source is turned off at the end of the sweep, then the VNA will wait for this settling time before continuing with the next sweep.

  • "Settling Time" only affects timing at the beginning and end of the sweep. If the SMU output is changed during a sweep (per point), the "Settling Time" does not affect the settling timing for each point.

  • This is set per-channel and the same for all SMUs.

 

Channel  Specifies the target channel to setup.

SMU  Specifies the target SMU to setup

Set Output Level  Open DC Source Dialog box to specify the output level

 

 

Input dialog box help

Current Sense Range  Selects one of three current sense ranges

Measurement Points  Sets the number of points to be measured, from 0 to 100,000

Measurement Delay Points  Sets the number of offset points relative to the trigger

 

Channel  Specifies the target channel to setup.

SMU  Specifies the target SMU to setup

Configure PXI SMU M9614A/ M9615A

M9615A is controlled with SCPI. The communication protocol is HiSLIP and SCPI driver is defined by an external .xml file.

Procedure to enable M9614A/ M9615A

 

1. For the first time using M9614A/ M9615A, user has to install the driver.  

Visit www.keysight.com/find/m9614a or www.keysight.com/find/m9615a to get the latest version of the M9614A/M9615A software. Unzip the downloaded software and firmware, if the downloaded file is zipped. (.zip file)

Then Copy the M960x software installer (.exe file) into the controller. Launch it and follow the instruction prompts to install the software.

 

2. Launch the SCPI server with VNA launcher.

  

If M9614A/ M9615A module is in the chassis, VNA launcher can find it automatically.

When the M9615A is selected, the SCPI server is launched. If multiple M9615A are selected, each module will have its own SCPI server likes below.

  

For the first time using, user has to add it as LAN instrument in Keysight Connection Expert.

 

3. Add M9615A as external device. Go to Setup -> External Hardware -> External Device

  

Name  Specify your desired device name

Device Type  Choose SMU from the dropdown list.

Driver  Choose M960X_DMM from the dropdown list. The M960X_DMM.xml file driver is included in the VNA firmware install package.

Active-Show in UI  Check to make the device available for use in the relevant dialogs.

IO Configuration  Click "..." button to open the Select VISA Resource dialog as below.

     

Resource Finder  Select LAN from the dropdown list and click Find.

Select the VISA that has been set up in Keysight Connection Expert.

 

4. Make DC Measurements.

In new trace dialog, voltage and current parameters can be found from the “Aux” tab.

The trace is DC readings.

 

5. Customize the external device.

User can customize the control in Device Properties dialog. User can edit the most frequently used elements that are defined in GUI. After save the it, it will update the .xml driver file automatically.
