niRFSA Configure IQ Rate

NI RF Vector Signal Analyzers

niRFSA Configure IQ Rate

Configures the rate at which the device samples IQ values. Bandwidth is equal to the coerced IQ rate times 0.8.

Note Note  You should not need to configure an IQ rate higher than 25 MHz, since the NI PXI-5600 downconverter bandwidth is 20 MHz. If you choose to configure a higher IQ rate, you may see aliasing effects at negative frequencies because the IF frequency of the downconverter is at 15 MHz.

cio.gif instrument handle identifies your instrument session. instrument handle is obtained from the niRFSA Initialize or the niRFSA Initialize With Options VIs and identifies a particular instrument session.
cdbl.gif IQ rate specifies the IQ rate for the acquisition. The value is expressed in S/s.
ccclst.gif error in (no error) describes error conditions that occur before this VI runs.
cbool.gif status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.
ci32.gif code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.
cstr.gif source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning. The default is an empty string.
iio.gif instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niRFSA Initialize or the niRFSA Initialize With Options VIs and identifies a particular instrument session.
icclst.gif error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI produces.
ibool.gif status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
ii32.gif code the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
istr.gif source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning.
