Control the receiver simulation box.

Mandatory Arguments:

(none)

Optional Arguments:

Receivers noise

The set of receivers to pass noise to.

SwitchState signal

Receivers quad

The set of receivers whose phases are to be shifted by 90 degrees.

Example:

The following example connects noise sources to the inputs of all receivers and turns on the fake sky signal. It leaves the quadrature phase switch settings unchanged.

  rxsim noise=all, signal=on

Example 2:

The following example turns off the noise sources of all receivers, but doesn't change the quadrature phase switch states or the state of the fake sky signal.

  rxsim noise=none

Example 3:

The final example turns on the quadrature phase switch of receivers 0 and 2 and turns off the quadrature phase switches of the rest of the antennas.

  rxsim quad=rx1+rx2

Context:

To correlator test box contains 13 noise sources which simulate the noise generated by each of the CBI receivers. It also contains a common signal generator that can be injected into either all or none of the correlator reciever inputs. Finally a 90 degree phase shifter can selectively be inserted into the signal paths of each correlator input. This box is controlled by the rxsim command via a digital I/O board.
