Test of Model CBM-46061A Amplifier for Sub-Aqueous Echo Ranging
The subject equipment was set up in a screened booth with the necessary testing equipment. It was given a general mechanical inspection, and subjected to electrical tests to determine its performance with regard to the following: (a) Input impedance. (b) Power consumption. (c) Sensitivity. (d) Selectivity. (e) Image Response. (f) Intermediate frequency rejection. (g) Overload selectivity. (h) Resonant overload. (i) Frequency and gain stability. (j) Limiter control. (k) Audio overload. (l) Audio fidelity (m) Output impedance. (n) Maximum noise level. (o) Calibration accuracy. (p) Blocking.
