The Tektronix 067-0502-00 is an instrument designed for calibrating oscilloscope calibrators. It is very similar to the 067-0502-01. What are the differences?
Sherman Foy contributed the following information:
TekWiki asks the question: what is the difference? I have both units and have done an extensive review.
Looking @ the front panels [TNX 4 pix] of the –00 & the –01, it seems that the –01 dropped the X100 Amplifier section. The front panel is re-laid out, but what remains seems to be identical to the corresponding sections from the –00. IOW, the –00 is a superset and the –01 is a subset of the -00.
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 @ the following table. I am using a re-organization of the sheets, the block diagram of the –00 and this table:
|Section||-00||-01||Sheet in -00||Sheet in -01||Sheet in proposed consolidated drawing set|
|Square Wave calibrator||Used in both||Used in both||1||1||[s/b 1]|
|X100 Amplifier||Used in -00||Used in -01||2||--||[s/b 2]|
|Power Supply||-00 has more sections||Than –01||3||2||[s/b 3A for -00 & 3B for -01]|
