IviPwrMeter Extension Capability Groups
The IviPwrMeter class driver identifies functions and attributes that belong to an extension group with the following abbreviations. Instrument specific drivers are not required to implement any of the extension capability groups. If you use functions and attributes that belong to extension capability groups, every instrument specific driver that you use must implement those extensions.
| Group Name | Description |
|---|---|
| IviPwrMeterChannelAcquisition | Supports power meters that can perform simultaneous measurements on two or more channels and fetch the measurement from each specified channel. Includes attributes for enabling a channel for measurement and functions for acquiring measurements on a specified channel |
| IviPwrMeterManualRange |
Supports power meters that can manually specify the upper and lower limits of the measurement range. Includes functions for configuring the measurement range. |
| IviPwrMeterTriggerSource | Supports power meters that can specify a trigger source and a trigger event on which to trigger a measurement. Includes functions for configuring the trigger source. |
| IviPwrMeterInternalTrigger | 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. Includes functions for configuring these attributes. |
| IviPwrMeterSoftwareTrigger | 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. |
| IviPwrMeterAveragingCount | Supports power meters that can filter a signal by averaging it a specified number of times in manual averaging mode. Defines an attribute and function to specify the averaging count. |
| IviPwrMeterZeroCorrection | Supports power meters that can perform a zero correction on an input channel. Defines functions to perform the zero correction. |
| IviPwrMeterDutyCycleCorrection | Supports power meters that perform a duty cycle correction. Includes functions for enabling and configuring the duty cycle correction. |
| IviPwrMeterCalibration | Supports power meters that can perform calibration for a given power sensor. Defines functions to perform the calibration. |
| IviPwrMeterReferenceOscillator | Supports power meters that can enable an internal reference oscillator. Defines attributes that configure the reference oscillator and the functions that set these attributes. |
