NI 5431 Composite Video Generator
HL Configure Sequencer
This high-level VI configures the NI 5431 sequencer, which is the play-list that will create the correct video signal generation. The example Basic Create Composite Signal from BMP Image shows how to correctly use this VI.
 |
instrument handle in is the VISession handle that you get from the NI-FGEN Initiate or Initiate With Options VIs. The handle identifies a particular instrument session. |
 |
sequence length is used for single frame generation. Connect this input to the corresponding output of a VI such as HL Calculate and Download Video Data. |
 |
waveform handles array is used for single frame generation. Connect this input to the corresponding output of a VI such as HL Calculate and Download Video Data. |
 |
error in is a cluster that describes the error status before this VI executes. If error in indicates that an error occurred before this VI was called, this VI may choose not to execute its function, but just pass the error through to its error out cluster. If no error has occurred, then this VI executes normally and sets its own corresponding error message. Using error in and error out clusters is a convenient way to check errors and to specify execution order by wiring the error output from one subVI to the error input of the next. |
 |
Output level (mV/IRE) specifies the output level of the generated video signal. (Default = 7.000 mV/IRE). |
|
Offset specifies the offset of the generated video signal. (Default = 0.112 V results in 0 V output at the blanking level of the video signal). |
 |
instrument handle out is the VISession handle that you get from the NI-FGEN Initiate or Initiate With Options VIs. The handle identifies a particular instrument session. |
 |
error out is a cluster that describes the error status after this VI executes. If an error occurred before this VI was called, error out is the same as error in. Otherwise, error out shows the error, if any, that occurred in this VI. Use the error handler VIs to look up the error code and to display the corresponding error message. Using error in and error out clusters is a convenient way to check errors and to specify execution order by wiring the error output from one subVI to the error input of the next. |
