ni5640R session identifies the instrument session. ni5640R session is obtained from the ni5640R Init Acquisition Session or the ni5640R Init Generation Session VI.

channels to enable specifies the channel(s) to enable.

The valid syntax for this parameter is a comma-delimited list of channel numbers. To specify all channels, use an empty string ("").

carrier frequency specifies the carrier frequency of the generated IF signal.

IQ rate specifies the I/Q rate for the generation. The value is expressed in samples per second (S/s). The digital filter passband is 0.4 * I/Q rate. For example, if the I/Q rate is 12.5 MHz, you can see signals from -5 to +5 MHz.

This value is coerced to the next highest supported value. You can query the coerced value using the ni5640R Get Actual IQ Rate VI.

Note: Any frequency content should be at most 0.4 * the actual I/Q rate. Any signal higher than 0.4 * the actual IQ rate could cause aliasing and/or numerical overflows.

power level specifies the desired peak power level for the analog output.

cbool.gif

number of samples is finite specifies whether to configure the device to generate a finite number of samples or to generate samples continuously.

ci32.gif

number of samples specifies the number of samples to acquire if number of samples is finite is set to TRUE.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

ni5640R session out passes a reference to the instrument session to the next VI. ni5640R session was obtained from the ni5640R Init Acquisition Session or the ni5640R Init Generation Session VI.
