Figure 4-15. Manual Sweep Accuracy
P. Using the equation: Flatness Error (dB) = 20 Log
(Displayed Amplitude/7.50V),
calculate the Flatness
Error in dB for each amplitude entered in the Perfor-
mance Test Record. Compare the result of each calcula-
tion to the specification given in the table.
4-15. MANUAL SWEEP ACCURACY
This test checks the accuracy
of the 3314A Manual
Linear Sweep.
Specification:
Manual Linear Sweep Accuracy:
Stop Range = 20MHz
+3% of Stop Frequency
Stop Range = 2MHz
+ 1% of Stop Frequency
Stop Range < 200kHz + (0.2% of Stop Frequency
+ 0.1% of Range)
Equipment Required:
Universal Counter
50 Ohm Feedthrough Termination
Procedures:
A. Preset the 3314A.
B. Set the 3314A as follows:

D. Connect the 3314A to the Counter as shown in
Figure 4-15.
E. Press the *MAN
SWEEP"
key оп the 3314A.
F. Press "START FREQ".
G. Record the frequency reading on the Universal
Counter. Reading should be IMHz
x 300kHz.
H. Set "STOP FREQ" on the 3314A to IMHz and
"START FREQ" to 100kHz.
I. Record
the frequency reading on the Universal
Counter. The reading should be 100kHz
+ 10kHz
J. Set "STOP ЕКЕО" on the 3314A to 100kHz and
"START FREQ" to 10kHz.
K. Record the frequency reading on the Universal
Counter. The reading should be 10kHz
+ 400Hz.
4-18. STEP ATTENUATOR ACCURACY
This test compares the accuracy of the 3314A Step At-
tenuator against an attenuator of known precision.
