Re: [BLAST_TOF] Analog adders

a) should read "sending 1, 2 or 3 equal pulses of 300mV each produced
about 300, 450, 550mV output".

        Probably clear to everyone, but just in case...

        Not only is it difficult to gain match, but with the non-linearity, it
is possible an analog output from the adder could look the same for (a
large noise pulse in 1 tube) or for (a smaller electron signal in each
tube).
