General Safety Considerations
WARNING
WARNING
CAUTION
WARNING
WARNING
Before this instrument is switched on, make sure it has been properly
grounded through the protective conductor of the ac power cable to a
socket outlet provided with protective earth contact.
Any interruption of the protective (grounding) conductor, inside or
outside the instrument, or disconnection of the protective earth terminal
can result in personal injury.
There are many points in the instrument which can, if contacted, cause
personal injury. Be extremely careful. Any adjustments or service
procedures that require operation of the instrument with protective
covers removed should be performed only by trained service personnel.
Before this instrument is switched on, make sure its primary power circuitry
has been adapted to the voltage of the ac power source.
Failure to set the ac power input to the correct voltage could cause damage to
the instrument when the ac power cable is plugged in.
No operator serviceable parts inside. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.
If this instrument is used in a manner not specified by Hewlett-Packard
,
Co., the protection provided by the instrument may be impaired.

What You’ll
Find in This
Chapter
This chapter describes the process of getting the cable TV analyzer ready
to use when you have just received it. See “Preparing Your Analyzer For
Use” for the process steps. The process includes initial inspection, setting
up the unit for the selected ac power source, and performing automatic
self-calibration routines. Information about static-safe handling procedures is
also included in this chapter.

8591C
cable TV
analyzer is a portable instrument ideal for field use. It comes in a durable
carrying case that makes it easy to transport and protects it from moisture
and dirt. The cable TV analyzer is fully operational within the case so you
never need to remove it.
The HP
8591C
cable TV analyzer comes equipped with the HP
85721A
cable TV measurements and system monitor personality installed. The
cable TV measurements and system monitor personality is a downloadable
program (DLP) consisting of measurement routines useful for cable television
applications.

Preparing Your Cable TV Analyzer for Use
Detailed information for all of the steps in this process is included in this
chapter immediately following the process description.
1. Unpack the cable TV analyzer from the shipping container and inspect it
for damage during shipping.
2. Verify that all of the accessories and documentation has been shipped.
3. Check that the line voltage selector on the rear panel is set to the proper
voltage for your area.
4. Check that the correct fuse is in place.
WARNING
Failure to ground the cable TV analyzer properly can result in personal
injury. Use an ac power outlet that has a protective earth contact. DO
NOT defeat the earth grounding protection by using an extension cable,
power cable, or autotransformer without a protective ground conductor.
5. Connect the power cable to the cable TV analyzer and press the front
panel
m
switch to turn it on.
6. Execute the self-calibration routines after allowing the cable TV analyzer
to warm up for 30 minutes. Chapter 2 includes guidelines on how often
the routines should be performed.
7. Connect CAL OUT to INPUT 75

Initial Inspection
Inspect the shipping container for damage. If the shipping container
or cushioning material is damaged, keep it until you have verified that
the contents are complete and you have tested the cable TV analyzer
mechanically and electrically.
lhble
l-l contains the accessories shipped with the cable TV analyzer. If
the contents are incomplete or if the cable TV analyzer does not pass the
verification tests in the calibration guide, notify the nearest Hewlett-Packard
office. If the shipping container is damaged or the cushioning material shows
signs of stress, also notify the carrier. Keep the shipping materials for the
carrier’s inspection. The HP office will arrange for repair or replacement
without waiting for a claim settlement.
If the shipping materials are in good condition, retain them for possible future
use. You may wish to ship the cable TV analyzer to another location or to
return it to Hewlett-Packard for service. See “How to Return Your Analyzer
for Servicing, D in Chapter 8 for more information about shipping materials.
NOTE
Complete instructions for installing your cable TV analyzer in an equipment rack are provided in a

Power Requirements
The cable TV analyzer is a portable instrument and requires no physical
installation other than connection to a power source.
CAUTION
Do not connect ac power until you have verified that the line voltage is
correct, the proper fuse is installed, and the line voltage selector switch is
properly positioned, as described in the following paragraphs. Damage to the
equipment could result.
Table 1-2. Power Requirements

l-2.
Setting the line Voltage Selector Switch
CAUTION
Before connecting the cable TV analyzer to the power source, you must set
the rear-panel voltage selector switch correctly to adapt the cable TV analyzer
to the power source. An improper selector switch setting can damage the
cable TV analyzer when it is turned on.
Set the instrument’s rear-panel voltage selector switch to the line voltage
range (115 V or 230 V) corresponding to the available ac voltage. See
Figure l-2. Insert a small screwdriver or similar tool in the slot and slide the
switch up or down so that the proper voltage label is visible.

Checking the Fuse
Figure 1-3. Checking the Line Fuse
Preparing For Use
Power Requirements
The recommended fuse is size 5 by 20 mm, rated
F5A,
250 V (IEC approved).
This fuse may be used with input line voltages of 115 V or 230 V. Its HP part
number is 2110-0709.
With an input line voltage of 115 V an alternate fuse can be used. In areas
where the recommended fuse is not available, a size 5 by 20 mm, rated fast
blow, 5 A, 125 V
number is
2110-0756.
(UL/CSA
approved) fuse may be substituted. Its HP part
The line fuse is housed in a small container beside the rear-panel power
connector (see Figure l-3). The container provides space for storing a spare
fuse, as shown in the figure.
