niRFSA Configure Resolution Bandwidth VI

Configures the resolution bandwidth of a spectrum acquisition. The resolution bandwidth controls the width of the frequency bins in the power spectrum computed by NI-RFSA. A larger value for resolution bandwidth creates wider frequency bins, which results in fewer bins, or spectral lines.
By default, the resolution bandwidth value corresponds to the 3 decibels (dB) bandwidth of the window type NI-RFSA uses to compute the spectrum. To directly specify the frequency bin width, set the Resolution Bandwidth Type property to Bin Width.
Supported Devices: PXIe-5644/5645/5646, PXI-5661, PXIe-5663/5663E/5665/5667/5668, PXIe-5820/5830/5831/5832/5840/5841/5842/5860

Inputs/Outputs
instrument handle
—
instrument handle identifies your instrument session. instrument handle is obtained from the niRFSA Initialize VI or the niRFSA Initialize With Options VI.
resolution bandwidth (Hz)
—
resolution bandwidth specifies the resolution bandwidth of a spectrum acquisition, in hertz (Hz). Configure the type of resolution bandwidth with the Resolution Bandwidth Type property.
error in
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
instrument handle out
—
instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niRFSA Initialize VI or the niRFSA Initialize With Options VI and identifies a particular instrument session.
error out
—
error out contains error information. This output provides standard error out functionality. |
