Page 4: Overview
Overview The L-1 Standards Model 3300 Transimpedance Amplifier (TIA) is a precision elec- tronic instrument designed to measure photocurrents to very low uncertainties, for the most demanding optical metrology applications. The amplifier senses the cur- rent flowing into/out of its input, which is held at constant potential (virtual ground), and supplies a proportional analog potential at its output.

Page 13: Set Up
Set Up The Model 3300 Transimpedance Amplifier must be used with a correct communica- tion/power supply unit, either Model 3310 TIA Power Supply or Model 3311 TIA Quad Power Supply. The Model 3310 TIA Power Supply can only be used with one TIA unit.

Page 22: Command Guide
The TIA must only be sent a single command/line at any given time. An acknowledg- ment/response will be returned by the TIA when each command is completed. Sub- sequent commands sent to the TIA before it returns acknowledgment will be ignored. Model 3300 Transimpedance Amplifier (TIA) User Manual Rev3...

Page 24 Two commands are implemented that pertain only to the Quad Power Supply. These commands (“get_TIA_pres” and “set_ethernet”) are not forwarded to any Model 3300 TIAs connected to the power supply. GETSERNUM (or GetSerNum) Description: The GETSERNUM command, for “get serial number”, prompts the TIA to return its unit serial number.
