User Querying
Querying the value of the Device Temperature (°C) property or the NIRFSG_ATTR_DEVICE_TEMPERATURE attribute returns the internal temperature of the NI 5610.
 |
Note The temperature sensor queried by the Device Temperature (°C) property or the NIRFSG_ATTR_DEVICE_TEMPERATURE attribute is within the NI 5610 RF enclosure and contains an internal clock that is activated when the sensor is enabled. This clock can cause low-level close-in phase noise spurs, usually below -70 dBc that vary from unit to unit. For this reason, NI highly recommends that the temperature sensor not be continuously queried to maintain a cleaner spectrum. |
