Model 1317A
Performance Check
SECTION V
PERFORMANCE CHECKSAND ADJUSTMENTS
5-1.
INTRODUCTION.
5-2. This section contains step-by-step procedures
for checking Model 1317 A specifications as shown in
Section I of this manual. A table (performance check
record) is provided at the end of the performance
checks for recording the measurements taken during
the first running of the procedure. The procedures for
making all internal adjustments are covered follow-
ing the performance check procedures. A photograph
showing the locations for all adjustment controls is
located at the end of this section.
a-3. The procedures assume that the instrument
will perform as specified. Should there be a failure
to
obtain the desired result during either the checkout
procedures or the adjustment procedures, the cause
should be found and corrected before proceeding
further. Refer to the adjustments in this section and
to the instructions on troubleshooting in Section VIII
of this manual.
5-4. Test equipment required for procedures in this
section is listed in table 5-1. Test equipment equiva-
lent to that recommended may be substituted, pro-
vided it has the required characteristics listed in the
table. For best results, use recently calibrated test
equipment.
5-5.
PERFORMANCE CHECKS.
WARNING
I
Do not attempt to operate this instru-
ment until the safety summary, located
just before Section I, has been read and
understood.
5-6. The following paragraphs describe procedures
t6 determine if the instrument meets the specifica-
tions listed in the specification table located in Sec-
tion 1. These procedures can be used as part of an
incoming inspection, as a periodic operational test,
or
to
check calibration after repairs or adjustments
have been made. Anyone of the following checks
can be made separately, if desired.
5-7. The first time the performance checks are
made, enter the results on the performance check
record. Be sure
to
enter the instrument serial number
on the record for identification. Remove the record
and file it for future reference.
5-8.
DEFLECTION AMPLIFIER RISETIME.
5-9. Required
Result. Risetime,
measured
be-
tween the 10% and 90% points on the displayed wave-
form, shall be equal to or less than 70 nanoseconds
for both the x and y amplifier.
5-10. Procedure.
a. Perform preoperational procedure (Section
III).
b. Set 50{2110K switches (on boards Al and A3)
to 500.
c. Connect equipment as shown in figure 5-1.
d. Set frequency of square wave generator to
100 kHz.
e. Adjust monitor oscilloscope and amplitude
of square wave generator output for full scale ver-
tical deflection on monitor oscilloscope.
f. Observe risetime between 10% and 90%
points (dotted lines on monitor oscilloscope).
g. Disconnect square wave generator from
X
INPUT and connect to
Y
INPUT.
h. Disconnect probes from horizontal deflection
plates and connect to vertical deflection plates.
i. Repeat steps e and f.
5-11. DEFLECTION AMPLIFIER BANDWIDTH.
5-12. Required Result. When comparing equal
amplitude 50-kHz and 5-MHz input signals, band-
width of both the x and y amplifiers shall be down no
more than 3 dB at 5 MHz.
5-13. Procedure.
a. Perform preoperational procedure (Section
III).
b. Set 500/10K switches (on boards Al and A3)
to 500.
c. Connect equipment as shown in figure 5-2.
d. Set frequency of constant amplitude signal
generator
to
50 kHz.
