US 8,525,093 B2 · Automatic set-up for instrument functions

Abstract

Machine-implemented methods and apparatuses to automatically set-up a signal processing system are described. The signal processing system is set to a first bandwidth. A sampling frequency of the signal processing system is set to a first sampling frequency. Next, first samples of first signals are received at the first bandwidth and the first sampling frequency. First parameters of the first signals based on the first samples are determined. Next, a second sampling frequency is determined based on the first parameters to sample second samples. The first parameters of the first signals may be a mean transit time, a minimum transit time, a mean frequency of the signals, and a standard deviation of the frequency of the signals. Next, a mixer frequency is determined based on the first parameters. A low pass filter is set based on the mixer frequency.

Dependent claims

A machine-implemented method to adjust a gain of a signal processing system, comprising:

setting a gain to a first value;
receiving signals;
measuring intensities of the signals;
and
adjusting the gain to a second value based on the intensities, so that a smallest intensity of the signals is higher or equal to a detection level of the system and a largest intensity of the signals is less or equal to a saturation level of the system.
