The '''4054''' is a version of the 4052 built around the 19" screen from the [[4014]] terminal rather than the 11" screen from the [[4012]], increasing display resolution to 4,096 by 3,072. The 4054 also had an option to display a limited amount of refreshed graphics that used a [[wikipedia:Signetics 8X300|Signetics 8X300]], an early RISC-like microprocessor.

In early 1980s, Tektronix introduced the 4052A and 4054A facelift models, changing from ROMs with patch ROMs to EPROMs for the firmware, and replacing the discrete GPIB software implementation with a [[TI9914]] GPIB controller for higher GPIB performance.
