For more information, write
Dept. A-1,
The newly designed Model 1010 digital computer uses true signal averaging rather than straight summation or weighted average methods. Sweep speeds range from FABRI-TEKInstruments, Inc. 20 microseconds per address to 200 seconds for a complete 256 address sweep. It's easier to operate ; even the oscilloscope and X-Y recorder outputs are calibrated by pushbutton.
