The Tektronix 475 is a portable dual-trace oscilloscope with dual time-bases similar to the 465, but with 200 MHz bandwidth and a maximum vertical sensitivity of 2 mV/Div. It is all solid-state except for the CRT. It was introduced in November 1972.

A revised version, the 475A, has 250 MHz bandwidth and a maximum vertical sensitivity of 5 mV/Div. The 1106 is a battery pack for the 475.

The optional DM44 multimeter attaches to the top of the instrument.
