ATTENUATOR
Figure 4-17. Vernier Attenuator Flatness
H. Record the Marker Amplitude displayed on the
CRT in the appropriate section of Table 4-10 located in
the Performance Test Record.
I. From the reading taken in step H, subtract the In-
sertion Loss Error of the Attenuator. Add that quantity
to the Attenuator's setting and enter the result under "Ас-
tual Attenuation' m Table 4-10. (See Performance Test
Record for example.)
NOTE
The
"Actual Attenuation" calculated for
settings of 10dB & 20dB at 10kHz is the
reference attenuation to which "Actual At-
tenuation"' at 50kHz,
IMHz,
апа 20MHz
will be compared. (See Table 4-10.)
J. Set the Attenuator to IOdB.
K. Set the amplitude of the 3314A to 10.0Vp-p and
the frequency to 50КН2.
L. Repeat steps E through I.
M. Set the Attenuator
to 10dB.
N. Set the amplitude of the 3314A to 10.0Vp-p and
the frequency to 1MHz.
O. Repeat steps E through I.
P. Set the Attenuator to 10dB.
Q. Set the amplitude of the 3314A to 10.0Vp-p and
the frequency to 19.99MHz.
R. Repeat steps E through I.
S. Set the Attenuator to 20dB.
T. Set the amplitude of the 3314A to 10.0Vp-p and
the frequency to 10kHz.
U. Repeat step E.
V. Set the amplitude of the 3314A to 1.00Vp-p.
W. Set the Attenuator to OdB.
X. Repeat steps H & I.
Y. Set the Attenuator to 20dB.
Z. Set the amplitude of the 3314A to 10.0Vp-p and
the frequency to 50kHz.
A.A, Repeat steps E, V-X.
B.B. Set the Attenuator to 20dB.
C.C. Set the amplitude of the 3314A to 10.0Vp-p and
the frequency to IMHz.
D.D.
Repeat steps E, V-X.
E.E. Set the Attenuator to 20dB.
F.F. Set the amplitude of the 3314A to 10.0Vp-p and
the frequency to 19.99M Hz.
G.G. Repeat steps E, V-X.
