HORIZONTAL (X) AMPLIFIER
Polarity (-X INPUT) Positive signal applied de-
flects beam to the left; nega-
tive signal deflects beam to
Satisfactory operation is
substantiated by other tests.
Common-Mode Rejection
DC to 100 kHz At least 100:1 cmr ratio for
(1X attenuation.)
A 100-kHz, 10 V (p-p) sine
wave is applied to both the
+X and -X INPUTS. Length
Check Horizontal Common-
Mode Rejection.
100 kHz to 1 MHz At least 50:1 cmr ratio for
(1X attenuation.)
A 1-MHz, 10 V (p-p) sine
wave is applied to both the
+X and -X INPUTS. Length of
horizontal trace is checked.

Common-Mode Rejection
DC to 100 kHz
(1X attenuation.)
A 100-kHz, 10 V (p-p) sine
wave is applied to both the
+¥ and -Y INPUTS. Length of
vertical trace is checked.
Check Vertical Common-
Mode Rejection.
100 kHz to 1 MHz At least 50:1 cmr ratio for

Common-Mode Rejection.
100 kHz to 1 MHz
A +10 ys ramp is applied to
the +X INPUT. A 1-MHz, 10 V
(p-p) sine wave is applied to
both the +Z and -Z INPUTS. A
test oscilloscope is connect-
ed to TP599 and the ampli-
tude of the Z-Axis output
signal is checked.
