Detailed Description

The SysPowerTable class is an Alma table.

Role: This table is intended to store power measurements based on a synchronous power detector as used at the EVLA. While the table is intended to be general enough for use with other arrays, it is deeply entwined with the EVLA data acquisition scheme. The units of $P_{diff}$ and $P_{sum}$ are such that the system temperature, $T_{sys}$ , is :
$T_{sys}=\frac{P_{sum}}{P_{diff}} . \frac{T_{cal}}{2}$
where $T_{cal}$ is the temperature of the noise tube.

timeInterval	ArrayTimeInterval		time interval over which the content of the row was measured.
Value (Mandatory)
numReceptor	int		The number of receptors.
Value (Optional)
switchedPowerDifference	vector<float >	numReceptor	the switched power difference $P_{diff}$ defined by $P_{diff} = G*(P_{on}-P_{off})$ .
switchedPowerSum	vector<float >	numReceptor	the switched power sum $P_{sum}$ defined by $P_{sum}=G(P_{on} + P_{off})$ .
requantizerGain	vector<float >	numReceptor	refers to the gain inserted after the synchronous power detector. For WIDAR, it is the requantizer gain ().

Constructor & Destructor Documentation

virtual asdm::SysPowerTable::~SysPowerTable ( ) [virtual]

asdm::SysPowerTable::SysPowerTable ( ASDM & container ) [private]

Create a SysPowerTable.

This constructor is private because only the container can create tables. All tables must know the container to which they belong.

Parameters:

container

The container to which this table belongs.
