Figure 4-3. Internal Trigger Accuracy
4-5, TRIANGLE LINEARITY
This procedure determines the linearity of the 3314A
Triangle wave at frequencies between 1Hz and 1kHz.
Specification:
+0.2%
Equipment Required:
High Speed Digital Voltmeter
50 Ohm Feedthrough Termination
Triax to BNC Connector
Procedures:
A. Preset the 3314A.
B. Set the 3314A as follows:

D. Connect the 3314A to the Voltmeter as shown in
Figure 4-4.
E. Note the Digital Voltmeter reading. Record this
value on the Performance Test Record under "Positive
Slope Measurement'.
This is the 10% point on the
positive slope of the Triangle (see Figure 4-5).
Е. Increment the delay on the Digital Voltmeter to
the values listed below. At each increment note and
record the corresponding voltage under ''Positive Slope
Measurement" in the Performance Test Record. (Each
increment
represents a 10%
segment
of the positive
slope.)

G. Measurements
for the
negative
slope
of the
Triangle wave are made by incrementing the delay on
the voltmeter to the values listed below. Note and record
the
corresponding
