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

Key Specifications

Output Signal DC+, DC-, Squarewave
Amplitude Range 0.2 mV to 100 V in 1−2−5 sequence, 5 mA in current loop
Amplitude Accuracy Within 0.25% into 1 MΩ load
Squarewave Repetition Rate 1 kHz within 20%
Maximum Input Voltage 100 V
100x Amplifier Gain Accuracy ±1%
100x Amplifier Risetime < 35  μs
100x Amplifier Output Range ≥ ±20 V, ±5 mA
100x Amplifier Output Resistance approx. 250 Ω

Comparison with 067-0502-01

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 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:

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]

Power Supply -00 has more sections Than –01 3 2 [s/b 3A for -00 & 3B for -01]
