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. 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]
T310	P/N 120-0442-00	P/N 120-0615-00	3	2	3A/3B
High voltage, B+	285 VRMS, 35 mA 300 VDC, 225 VDC & 100 VDC	285 VRMS, 35 mA 300 VDC, 225 VDC & 100 VDC	3	2	3A/3B
6.3 VAC (Chopper)	Used in -00	Used in -01, noted as 1.84A	3	2	3A/3B
100 VRMS (-100 VDC)	Used in -00, 40 mA	Used in -01, 31 mA	3	2	3A/3B

20 VRMS (X100 Filaments)	Used in -00	Not used in –01 T310	3	2	3A/3B
Floating power supply	Used in both; drives Square Wave MV	Used in both; drives Square Wave MV	4	3	[s/b 4]
