11A16
Template:Plugin Sidebar 2 The Tektronix 11A16 is a dual-channel 120 MHz current amplifier for 11300-series, 11400-series, DSA-series, and some CSA-series mainframes, depending on the version of the firmware.
Each channel has a 12-pin input connector that fits the A6302 probe (10.5 A continuous) or A6303 probe (52.5 A continuous).
The current probe input is an Amphenol 165-12 connector. It contains pins for hall element and transformer connections, lock detection, probe degaussing, and probe type encoding. The 11A16 detects the current probe type and scales the display appropriately.
The 11A16 uses one M377 amplifier chip per channel, U220 and U260.
