067-0502-00
The Tektronix 067-0502-00 is an instrument designed for calibrating oscilloscope calibrators. It is very similar to the 067-0502-01. The 067-0502-00 replaced the 067-0077-00.

Comparison with 067-0502-01

TekWiki asks the question: What is the difference? I have both units and have done an extensive review.
Looking at the front panels [TNX 4 pix] of the –00 & the –01, it seems that the –01 dropped the × 100 Amplifier section. The front panel is re-laid out, but what remains seems to be identical to the corresponding sections from the –00. In other words, the –00 provides a superset of the functionality of the -01.
Note that the –00 transformer [T310] has 6 windings and the –01 transformer [also T310] has 5 windings. Some currents are different, as indicated.
I have made my own notes for the project of working on the two. Using the schematics for organization, I arrived at the following table. I am using a re-organization of the sheets, the block diagram of the –00 and this table:
