Tektronix 475A - Rear Panel; Left Side Panel; Right Side Panel

MIX: The first part of the horizontai sweep is displayed
at a rate set by the A TIME/DIV switch and the latter part of
the sweep at a rate set by the B TIME/DIV switch. Relative
amounts of the display allocated to each of the two sweep
rates are determined by the setting of the DELAY-TIME
POSITION control.
A INTEN: The sweep rate is determined by the A
TIME/DIV switch. An intensified portion appears on the
display during the B Sweep time, which is about 10 times
the B TIME/DIV switch setting. This switch position
provides a check of the duration and position of the B
Sweep (delayed sweep) with respect to the A Sweep
(delaying sweep).
B DLYD: The sweep rate is determined by the B
TIME/DIV switch with the delay time determined by the
setting of the DELAY TIME (A TIME/DIV) switch and the
DELAV-TIME POSITION control.
REAR PANEL
45. A +GATE—Provides a positive-going rectangular —
pulse coincident with the A Sweep time, which can be
used to trigger the signal source (with TRIG MODE switch
set to AUTO).
46. B +GATE--Provides a positive-going rectangular
pulse coincident with the B Sweep time, which can be
used to trigger the signal source after a selected delay
time, providing that A Sweep is triggered internally.
47. CH 2 VERT SIGNAL OUT—Provides a sample of
the signal applied to the CH 2 input connector.
48. EXT Z-AXIS— Permits intensity modulation of the
crt display. Does not affect display waveshape. Signals
with fast rise and fall provide the most abrupt intensity
change. Signals must be time-related to the display for a
stable display. Useful for adding time markers in un-
calibrated modes of operation.
49. Line Fuse Hoider—Contains the line fuse and the
regulating range selector. See Table 1 for change informa-
tion.
50. Regulating Range Selector—Shown in Medium
regulating range. See Table 1 for change information.
51. PROBE POWER—Power source for active probe
systems.
52. Line Cord—Makes the connection between the
oscilloscope and the power source. The cord may be
conveniently stored by wrapping it around the feet on the
rear panel.
53. MOD SLOTS—A number in either slot indicates
the instrument contains an option or other modifications.
LEFT SIDE PANEL
Access for externaily available adjustments (see Fig. 7).
RIGHT SIDE PANEL
LINE VOLTAGE SELECTOR SWITCH (located on the
right side)-—Selects either 115 V or 230 V nominal line
voltage.
