A2488: dps with 800 Mhz rcvr



    A2488 is using double position switching on sources using the 800 Mhz receiver. The mock spectrometer is used to record the data. The setup is:

Compare polA with polB (10aug09)

    The observers reported that the rms for polB is about 70% larger than the rms for polB. This is measured across the dps spectra result.
    The dps processing is:
The processing leaves the dps spectra in units of the bandpass calibrator source strength.

Plots were made of the average spectral density  and rms value for 35  dps spectra (.ps) (.pdf):
