Getting Started
Electrical Installation
Before proceeding with product installation, please read the Safety
Summary at the front of this manual.
NOTE. Save the shipping carton and packing materials in case it
becomes necessary to ship the television demodulator to a Tektronix
Service Center for service or repair. Packaging instructions are on
page C–1.
AC Power Source
The television demodulator operates from an AC source with a line
voltage in the range 95 to 240 VAC and with a line frequency of 50 or
60 Hz.
The television demodulator is designed to operate from a single-phase
power source having one of its current-carrying conductors at or near
earth ground (the neutral conductor). Only the line conductor is fused
for over-current protection.
Systems that have both current-carrying conductors live with respect
to ground (such as phase-to-phase on multiphase systems) are not
recommended as power sources. A protective ground connection by
way of the grounding conductor in the power cord is essential for safe
operation.
Changing the Mains Voltage
The unit is designed to operate over the specified range (95 to
240 VAC) without the need for adjustment.
Power On Procedure
To power on the television demodulator, connect it to the AC power
source. There is no power switch. See Figure 1–1. The power on
sequence completes in about 10 seconds.
