OPERATINGINSTRUCTIONS
The 067-0599-00 Calibration Fixture was designed specifically for checking
or re-calibrating the performance of the Type 576 Curve Tracer. It pro-
vides accurate calibration voltages and currents for the Horizontal and
Vertical deflection circuits and accurate loads for the Collector Supply
and Step Generator circuits. The 067-0599-00 does this through the exter-
nal input and output lines at the 576 Test Fixture interface.
The VERTICAL, DISPLAYOFFSETMULTIPLIER, HORIZONTALand STEP GENERATOR
switches on the 067-0599-00 match the 576's switches with like names for
easy, direct-reading, comparison-style adjusting and checking, using the
576's own display for measurement. External monitoring of the 576's Step
Generator output is available through the 1 V/STEP (into 10,000 m) EXTER-
NALMONITORoutput jack.
Remove the Standard Test Fixture from the Type 576 and install the 067-0599-00
Calibration Fixture plug-in module. The 067-0599-00 is totally dependent
on the Type 576 for AC line voltage and regulated low voltage power supplies.
Turn the Type 576 on and allow at least 10 minutes warm-up before making
any checks or adjustments.
Because of the multiplicity and complexity of controls on the 576 and
067-0599-00 Calibration Fixture, checking apd/or adjusting the 576 should
be done sequentially according to the Performance Check/Calibration Pro-
cedure beginning on page 5-2 of the Type 576 Instruction Manual (Tektronix
Part Number 070-0905-00).
Performance Check Only
Beginning on page 5-4 of the 576 Manual, set all instrument controls accord-
ing to the listing. Plug the 3-pin connector from the 067-0599-00 into the
CAMERAPOWERjack of the 576 to provide a 75 0 load for the 576's +15 V
power supply. Begin performance checks with Step 5, page 5-8, doing only
those parts of each step labeled CHECKFOR - .
