Introduction
This performance check procedure is provided as a func­
tional check of the 067-0521-00 and may be used for incom­
ing inspection, quality assurance, etc. Failure to meet the
characteristics outlined will require internal checks a n d /o r
adjustment.
Recommended Equipment
The following equipment is recommended for a complete
performance check. Specifications given are the minimum
necessary to perform this procedure. All equipment is
assumed to be calibrated and operating within the original
specifications. If equipment is substituted, it must meet or
exceed the specifications of the recommended equipment.
For the most accurate and convenient performance check,
special calibration fixtures are used in this procedure. These
calibration fixtures are available from Tektronix, Inc. Order
by part number through your local Tektronix Field Office or
representative.
1. Real-time test oscilloscope. Must be capable of switch­
ing alternately between two time bases. Tektronix Type 547
recommended.
2. Sampling test oscilloscope. Must be capable of pre­
senting two inputs differentially. Minimum deflection factor
50 mv/division; bandpass to 0.825 gigacycle. Tektronix Type
561 A, with 3S76 dual trace plug-in and 3T77 sampling sweep
plug-in recommended.
3. Sine-wave generator frequency, 50 Me; output ampli­
tude 4 volts peak to peak; amplitude accuracy ± 3 % . Tek­
tronix Type 191 recommended.
4. Precision DC voltmeter. Accuracy within ± 0 .0 5 % ; meter
resolution 5 0 /xV; range 0 to 500 volts. For example, Fluke
Model 801 B.
5. DC voltmeter. Minimum sensitivity, 20,000 ohms/volt;
accuracy, check to within 1 % at 225 volts. For example,
Simpson Model 262.
6. Ohmmeter. Range, 400 ohms to infinite; accuracy,
± 3 % ; range voltage, 1 volt or more. For example, Simpson
Model 262.
7. Standard amplitude calibrator. Amplitude accuracy
0.025%; signal amplitude 0.5 volt to 100 volts; output signal
frequency, 1 kc. Tektronix calibration fixture 067-0502-00
recommended.
8. Flexible plug-in extension. Length 30 inches. Tektronix
Part No. 012-0038-00.
9. Cable. Impedance, 50 ohms; Type RG58A/U; length
42 inches, connectors BNC. Tektronix Part No. 012-0057-00.
10. Coupling capacitor, (two). Impedance 50 ohm; con­
nectors GR. For example, GR Type 874X, Tektronix Part
No. 017-0028-00.
11. Cable (two) Impedance, 50 ohms; delay time, 2 ns;
connectors GR. Tektronix Part No. 017-0505-00.
12. Modified rigid plug-in extension, see Fig. 6-1. Required
parts.
a. Rigid plug-in extension (two). Tektronix Part No.
013-0055-00.
b. Cable (two). Impedance, 50 ohms; delay time, 1 ns;
connector (one end only), GR. Tektronix Part No. 017-
0503-00.
c. Grommet (two). Size, 5/ 16 inch; material, rubber.
Tektronix Part No. 348-0003-00.
PERFORMANCE CHECK PROCEDURE
General
In the following procedure, test equipment connections
or control settings should not be changed except as noted.
Equipment used is listed under Recommended Equipment. If
substitute equipment is used, control settings or setup must
be altered to meet the requirements of the substitute
equipment.
NOTE
Since this is a perform ance check o f the 0 6 7 -0 5 2 1 -
00, the test oscilloscope w ith w hich it is used is
assumed to have been adjusted to perform w ith in
its specifications.
Preliminary Procedure
1. Connect the test oscilloscope to a line voltage within
the regulating range of its power supplies.
2. Set the 067-0521-00 and test oscilloscope controls as
follows:
3. Check— That the ohmmeter reading for each pin lies
between the values listed in Table 5-1 for that pin.
