Updates: 11-6-07 Some GDPs had noisy data with small signals at high temperatures. Also difficulties running 16 channels. 10-26-07 Some GDP's take twice as long to take data at frequencies 0.5 Hz and below. This is noticed when data is not taken every cycle but rather every other cycle. Please contact Bill for the solution. 10-11-07 TDIP v837 – fix asynchronous Zonge transmitter mode INI v838 – allow TD board cals to pass at 32Hz with 50Hz notch filters IN. CACCNVRT v200 – does not need index.cac file.
