General Information—606B
The Horizontal (X) and Vertical (Y) Amplifiers process the
input signals (either single-ended or differential) and
provide push-pull outputs to drive the crt deflection
plates. The input signals are applied through the
appropriate +• (noninverting) and -(inverting) INPUT
connectors.
The Z-Axis Amplifier controls the display intensity by
providing avoltage to drive the crt control grid. The input
signals (either single-ended or differential) are applied
through the appropriate +(noninverting) and -(inverting)
INPUT connectors.
The High-Voltage and Low-Voltage Power Supplies
provide all the voltages necessary for operation of this
instrument.
INSTALLATION
INITIAL INSPECTION
This instrument was inspected both mechanically and
electrically before shipment. It should be free of mars or
scratches and should meet or exceed all electrical
specifications. To confirm this, inspect the instrument for
physical damage incurred in transit and test the electrical
performance by following the Checkout Procedure in
Section 2, Operating Instructions. Verify performance
requirements by referring aqualified service person to
the servicing sections of the Service Manual. If there is
damage or deficiency, contact your local Tektronix Field
Office or representative.
OPERATING POWER INFORMATION
This instrument can be operated from either a 1'20-VdJt br
220-volt nominal line-voltage source, 48 to 440 hertz. In
addition, three regulating ranges are provided for each
nominal line-voltage source.
>CAUTION (
To prevent damage to the instrument, always
check the line- voltage information recorded
on the rear pane! before applying power to
the instrument.
Power Cord Information
WARNING
This instrument is intended to be operated
from asingle-phase earth-referenced power
source having one current-carrying conductor
(the Neutral Conductor) near earth potential.
Operation from power sources where both
current-carrying conductors are live with
respect to earth (such as phase-to-phase on a
three -wire system) is not recommended,
since only the line conductor has over-current
(fuse) protection within the instrument.
This instrument has athree-wire power cord
with apolarized two-pole, three-terminal plug
for connection to the power source and
safety-earth. The safety-earth terminal of the
plug is directly connected to the instrument
frame. For electric-shock protection, insert
this plug only in amating outlet with asafety-
earth contact.
Do not defeat the grounding connection. Any
interruption of the grounding connection can
create an electric-shock hazard. Before
making external connections to this
instrument, always ground the instrument
first by connecting the power cord to a
properly mated power outlet.

Line-Voltage and Regulating-Range Selection
Damage to the instrument may result from
incorrect placement of the line-voltage
selector plug. (See Ambient Temperature
Considerations, page 2-1.)
To select the correct nominal line voltage and regulating
range, proceed as follows:
1. Disconnect the instrument from the power source.
2. Insert the proper line-voltage selector plug (the brown
plug for 120-volt operation or the red plug 'for 220-volt
operation) on the line-voltage selector .pitfs (located. bn
the Low-Voltage Power &ZAxis board) labeled -for the
desired nominal line-voltage range. Refer to Figure K-1
for location and additional information^
3. Remove the line fuse from the fuse holder and check
for the correct rating Replace it with one having the
correct rating, if necessary. Refer to Figure 1-1 for fuse
information and location.

INSTALLATION IN PATIENT-CARE
FACILITIES
,o., Do not use the amplifier INPUTS for direct-
-patient connection. Signal currents at these
connectors, as well as leakage currents, may
exceed values considered nonhazardous for
direct-patient connection.
Although this Monitor is not to be connected
directly to apatient, interconnecting this
Monitor to other equipment can result in the
application of excessive current to apatient. It
is extremely important that the
interconnection is made in accordance with
NFPA 76B-5, Tentative Standard for the Safe
Use of Electricity in Patient Care Areas of
Health Care Facilities,section 3038, "Signal
Transmission Between Appliances”.
Among the situations involving the above-mentioned
patient hazard is one in which two or more pieces of
'Interconnected equipment are grounded at locations
'Vetnote from one another. The standard mentioned in the
’'preceding warning describes both this hazard and the
/appropriate corrective measures.
•?! •=?
,
INPUT ATTENUATION
The Horizontal (X) and Vertical (V) Amplifiers include
selectable 1X/5X step attenuators in both the +(non-
inverting) and the -(inverting) input circuits. These
attenuators extend the deflection factor range of the
appropriate amplifier to at least 12.5 volts for 8cm signal
.deflect (on. .Refer, .to' the Internal Control and Selector
.Locations foldout page in Section 8, Diagrams and Circuit
Board Illustrations for the position settings and locations
of the attenuator switches. To maintain proper
differential operation of the amplifier, always change
both the +and -attenuators to the same settings. These
step attenuators are set in the IX position when shipped
from the factory.
