|Numeric Value|Data
type|Access|Coercion|High Level Functions|
|1150167|ViReal64|R/W|None|None|
Specifies an uncalibrated digital-to-analog converter (DAC) value that scales the input signal before the signal modulates the carrier. A value of 0 completely attenuates the signal, and a value of 100 passes the full-scale signal to the modulator.
When using the PXIe-5654 with PXIe-5696, NI-RFSG may coerce AM sensitivity. Coercing the AM sensitivity prevents overpower conditions at the PXIe-5696 input. Read this attribute to determine the coerced value.
Default Value: 100
Valid Values: 0 to 100
