A Los Angeles Superior Court commissioner also ordered Steven George Hoover, 67, not to work with or have contact with children, said Deputy District Attorney Corene Locke-Noble.
Hoover's computer hard drive will be confiscated, and he is not to use the Internet during the probationary period, the District Attorney's Office reported.
Hoover also must register for life as a sex offender.
The same day he was charged, Hoover pleaded no contest Dec. 24 to two felony counts of possessing child pornography.
If Hoover complies with the terms of his probation for the next year, the charges can be reduced to misdemeanors by the court, according to the prosecutor.
Hoover was charged in connection with an investigation by the Los Angeles Police Department's Regional Internet Crimes Against Children Task Force and U.S. Immigration and Customs Enforcement's Los Angeles Child Exploitation Unit.
The State Bar of California, which licenses attorneys, will be notified of the attorney's conviction and sentence, the prosecutor said.
