niHSDIO stPMU Measure Voltage VI

Measures the voltage on the channels specified in the channel list parameter. You can call this VI at any time, including while in a digital state or a PMU state.
If you have not yet committed your session, calling this VI implicitly commits your session. If you have already committed your session by calling a VI such as the niHSDIO Commit VI, the niHSDIO Initiate VI, the niHSDIO Read Waveform VI, the niHSDIO Write Named Waveform VI, or the other Software-Timed PMU VIs, this VI will not commit your session again.

Note Only NI 6555/6556 devices support this VI. |

instrument handle identifies your instrument session. instrument handle is obtained from the niHSDIO Init Acquisition Session VI, the niHSDIO Init Generation Session VI, or the niHSDIO Init Ext Cal VI. |

channel list specifies the channels being configured. Specify multiple channels by using a channel list or a channel range. A channel list is a comma (,) separated sequence of channel names (for example, 0,2 specifies channels 0 and 2). A channel range is a lower bound channel followed by a hyphen (-) or colon (:) followed by an upper bound channel (for example, 0-2 specifies channels 0, 1, and 2). Use PFI1 or PFI2 to specify a valid PFI channel. Use DDC_CLKOUT or STROBE to specify a valid clocking terminal. If you configure multiple channels with this parameter, all those channels have the same settings. Selecting no channels for this parameter returns an error. |

aperture time (4E-6) configures the amount of time, in seconds, to measure each channel. The aperture time determines the number of hardware averages per measurement. The larger the aperture time, the greater the number of hardware averages. The default value for this control is 4E-6 (0.000004) seconds. |

voltage measurements returns an array of double-precision numbers representing the averaged measured voltages, per channel, in volts (V), over time. The order of the returned voltages directly corresponds with the order in which the channels are configured in the channel list parameter. |

error out contains error information. This output provides standard error out functionality.
