Specifies the expected thermal operating range of the instrument from the self-calibration temperature returned from the RFMXINSTR_ATTR_DEVICE_TEMPERATURE attribute. This value is expressed in degree Celsius.

Remarks


For example, if this attribute is set to 5.0, and the device is self-calibrated at 35 degrees Celsius, then you can expect to run the device from 30 degrees Celsius to 40 degrees Celsius with corrected accuracy and no overflows. Setting this attribute with a smaller value can result in improved dynamic range, but you must ensure thermal stability while the instrument is running. Operating the instrument outside of the specified range may cause degraded performance and ADC or DSP overflows.

You do not need to use a selector string if you want to configure this attribute for all signal instances. Specify the signal name in the selector string if you want to configure or read that signal instance. Refer to the Selector String topic for information about the string syntax.
