Interim correlator
02jun,2001
28aug12: polA sbc4 had
larger Tsys than other sbc.
15aug11: sbc1 polB spike in
center of band for bw <=12.5Mhz
07jul11: luis reburns chip
22jun11: sbc3,4 Tsys increase.
halfband filter 3,4 +5 volts supply failed.
07dec10: spectra
with low power levels (.1 to .5) do not show increased Tsys.
07oct09:
differential receiver chips for hardware blanking
29sep02: Spectral noise versus
integration time using noise source in downstairs if/lo.
28sep02: Spike in central channel of
correlator bandpasses (100 min integration).
25sep02: The correlator bandpasses using
a noise source.
24sep02: Comparing the computed and
measured bandpass shapes of the digitial filters/correlator.
