Calibration Procedure - Tektronix TYPE L Instruction Manual

Introduction
A complete procedure
operational standards and calibration of the
Type L Plug-In Unit is provided in this section
o f the manual. The steps in the procedure
are arranged in correct sequence to avoid
unnecessary repetition.
The step-by-step instructions also furnish
an orderly approach for isolation of malfunctions
which may develop.
cedure should be used in conjunction with
any maintenance and troubleshooting system.
If an abnormal indication
some point in the procedure, it is not usually
necessary to locate its cause before continuing
to the next step. Additional symptoms revealed
by perform ing further steps w ill frequently
sim plify the task of locating trouble.
F or this procedure, the L Unit should be
used in conjunction with a properly calibrated
Tektronix Type 540- o r 550-Series O scillo­
scope. Control settings are listed by the names
usually applied to them on the scopes with
which the Type L Unit may be used. Alternate
names are in parentheses.
Test equipment used in a particular step
should be left connected at the end of that
step unless instructions

to be in the positions they were in at the
conclusion of the preceding step.

Equipment Required
The following equipment or its equivalent
is required to perform a complete calibration
o f the Type L Plug-In Unit.
1. Test Oscilloscope, Tektronix 540- or 550-
Series.
2. Square-wave generator, Tektronix Type 105.
Required specifications are: 13-nsec risetim e
o r less; output frequencies of approximately
1 kc and 10 kc; output amplitude variable
from 10 to 100 volts across 600-ohm internal
load.
3. Square-wave generator, Tektronix Type 107.
Required specifications are: 3 nsec risetim e
o r less; output frequency of approximately 1 MC;
output amplitude variable to at least 0.35 volt.
4. Sine-wave generator, Tektronix Type 190( )
Constant-Amplitude Signal Generator. Required
specifications are: frequency range of 50 kc
to 13 MC; output amplitude of 0.14 volt or
m ore; output must be
o r automatically) fo r constant amplitude within
the above frequency range. Type 190( ) denotes
any model of the Generator.
5. Calibrated volt-ohmmeter (VOM), with sen­
sitivity of at least 20,0000/volt.
