Latest revision as of 04:48, 19 June 2024
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.
The military variant is called OS-261 C(v)1/0, which has a DC/DC converter (12/24 V input) on board.
The 475M is a standard 475 with enhanced environmental specs.
A revised version, the 475A (introduced in 1977), 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.
From Tekscope Vol. 4 No. 5, 1972:
Electrical design team [...] for the 475 under the leadership of Jim Hinze was: Jim Godwin, Les Larson, Steve Tosh, and Jim Woo.
