AMPLITUDE
ACCURACY
This test determines the amplitude accuracy
of
the
3314A's Sine, Square,
and
Triangle wave signals.
±
1010
of
setting ± 35mV
± 1%
of
setting ± 60mV
This test always results in positive phases.
Subtract 360
0
from the measured results to
obtain negative phase shifts.

Specifications:
NOTE
H.
The accuracy
of
the phase setting displayed on the
3314A can be determined by the following equation:
where t is the period
of
the 50Hz Synthesizer/Function
Generator signal (constant
throughout
the test),
and
t
l
is the change in time between the trailing edges
of
the
phase locked signals (varies with phase setting).
I.
Repeat step H for phase settings on the 3314A
of
- 90°,
0°,
+90°,
and
+ 199.9° noting that each phase
setting will have a corresponding value
of
t
l
to be
entered into the above equation.
The data taken above can be entered into the
Performance Test Record
for
permanent
reference and comparison.
