Syntax

There are three basic measurement modes - pulse power, modulated power, and statistical power. Each mode is targeted towards a specific type of measurement.The Pulse Mode is used with peak power sensors. The instrument functions as an enhanced peak power analyzer and provides the functionality of a random repetitive sampling oscilloscope for viewing and analyzing the RF power envelope of signals.The Modulated Mode is designed for continuous, true average power measurements of complex modulated signals. The Statistical Mode is used for advanced analysis of non-periodic modulated signals. This mode does not require a trigger event to make measurements and is useful for signals that are noise-like such as CDMA, OFDM, or QAM. In Statistical Mode, the RF signal is sampled continuously at high speed, without discarding or losing any data.

Declaration: Btn55xxx.h

Implementation: Btn55xxx.dll

Parameters

Vi

The ViSession handle that you obtain from the IviDriver_init or IviDriver_InitWithOptions function. The handle identifies a particular instrument session.

RepCapIdentifier

Must be VI_NULL or an empty string. This attribute is not defined on a repeated capability.

AttributeID

Must be BTN55XXX_ATTR_MEASUREMENT_MODE.

AttributeValue (GetAttribute)

Returns the current value of the attribute. The user must specify the address of a variable that has the same data type as the attribute.

AttributeValue (SetAttribute)

The value to which to set the attribute.

Remarks

Statistical mode is only valid for models 4541 and 4542. Statistical measurements can be enabled independentantly in the 55 Series USB power meters by enabling stastical capture at any time.
