Don't spend any extra time retransmitting the 9841i ODR. The missing records were right near the beginning, before the switch to one-way mode. If we are interested, we can issue a new query and delay the start time by an appropriate amount. I did that for the 9842i data. Even after the attenuator was changed during the second measurement, it looked to me like another 1 dB attenuation would have been worthwhile for the remainder of the SPC 10 pass. It might still be worthwhile to increase the attenuation there by 1 dB for the coming pass on 2001/142. Be well... Joe On 21-May-01 Aseel Anabtawi wrote: > Got the wrong email, again!
