IviPwrMeter Interchangeability
The IviPwrMeter class driver performs interchangeability checking when the IVIPWRMETER_ATTR_INTERCHANGE_CHECK attribute is set to VI_TRUE and you call one of the following functions:
In addition to the general interchangeability checking rules, the IviRFSigGen class defines additional rules and exceptions for the following capability groups.
| IviPwrMeter ManualRange |
Supports power meters that can manually specify the upper and lower limits of the measurement range. The IviPwrMeterManualRange extension capability also includes functions for configuring the measurement range. |
| IviPwrMeter InternalTrigger |
Supports power meters that can trigger internally on the measurement signal. It specifies attributes to configure the internal trigger event source, trigger level, and the trigger slope. Also includes functions for configuring these attributes. |
| IviPwrMeter SoftwareTrigger |
Supports power meters that can initiate a measurement based on a software trigger signal. You can send a software trigger to cause the power meter to trigger a measurement. |
| IviPwrMeter AveragingCount |
Supports power meters that can filter a signal by averaging it a specified number of times in manual averaging mode. The IviPwrMeterAveragingCount group defines an attribute and function to specify the averaging count. |
The IviPwrMeter class does not define additional interchangeability rules or exceptions for the following extension capability groups:
| IviPwrMeterChannelAcquisition | IviPwrMeterTriggerSource | IviPwrMeterDutyCycleCorrection |
| IviPwrMeterZeroCorrection | IviPwrMeterCalibration | IviPwrMeterReferenceOscillator |
