TSG95 Pathfinder™ User Manual
Getting Started
Please read the following statements before using your new TSG95
Pathfinder, then see the rest of the section for tips on supplying power, making preliminary settings, and connecting the instrument.
WARNING. Install or replace batteries only with the instrument
switched OFF and the AC adapter disconnected. Electrical shock or
equipment damage can result.
CAUTION. Do not attempt to operate the TSG95 with an improper
AC adapter. Damage to the instrument can result.
For best results, use the AC adapter and power cord supplied with
the instrument. If the supplied power cord is incorrect for the local
AC power supply, contact your nearest Tektronix representative.
The adapter voltage must be 9 to 15 VDC with an open-circuit voltage less than 18 VDC; the adapter connector must have the negative
(--) polarity contact in the center.
CAUTION. The AC adapter connector has +12 V on the outer casing.
Damage may result if it is allowed to come in contact with live
circuitry or other equipment. To prevent this, unplug the adapter
from the AC source before you unplug the adapter from the TSG95.
NOTE. Internal batteries are recommended when using an external
power adapter. A loose adapter connector can cause the loss of some
user settings and unexpected results the next time the instrument is
powered on.
The battery type, disposable or rechargeable, must be selected using
through the Utility menu (see page 6). Failure to select the proper
battery type can result in damage to the batteries and product.
TSG95 Pathfinder™ User Manual

Getting Started
Replace the batteries only wit h standa rd AA batteries (1.2--1.5 V,
nominal), or the Tektronix rechargeable battery pack listed on
page 73.
For more information, please contac t your nearest Tektronix representative or field office. In the United States and Canada, you can
also call the Tektronix information number, 1-800-TEK-WIDE
(1-800-835-9433), between 8:00 am and 5:00 pm Pacific time.
Supplying Power
The TSG95 is DC powered. You may power it with the standard AC
adapter, the optional 9.6 V NiCad battery pack, eight standard AA
batteries, or a “BP” type battery pack with the correct voltage and
polarity. The external DC power connector is on the left side of the
instrument.
To install AA batteries or the battery pack, open the battery compartment of the TSG95 by pressing down on the cover and sliding it in
the direction of the inscribed arrow, as shown above. When the cover
tabs line up with the slots in the case, lift the cover away from the
instrument. Install batteries in alternating directions as indicated by
the graphic molded into the “floor” of the battery compartment. If
using the optional battery pack, take the time to identify both contacts and install the pack properly.

H There is no need to remove the optional NiCad battery pack for
recharging. The TSG95 will “trickle charge” the battery pack
whenever the standard AC adapter is used. Recharging the
battery pack fully can take up to 16 hours. Note that charging
will occur only if the adapter supplies at least 12V; make sure
that the adapter you use is appropriate for the local AC supply.
H AA batteries are not included with the instrument; obtain them
locally. Rechargeable AA batteries may be used, but they will
NOT be recharged automaticall y by the AC adapter. To recharge
AA batteries, remove them from the instrument and use an
appropriate battery charger. For safety, read and follow the
battery charger instructions. Do NOT attempt to recharge
standard alkaline batteries.
H After a minute with no key-press, the TSG95 will automatically
switch to lock out mode (as if you had pressed the Lock Out
key); the display back light will shut off to conserve battery
charge. When you want to resume keypad input, press
exit lock out mode.
H To guard against battery discharge if you forget to turn the
TSG95 off after use, enable Auto Power Down through the
Utility menu (see page 6).

H The TSG95 can sense low battery voltage. It will warn you when
the charge is sufficient for approximately ten more minutes of
operation. The instrument will shut itself down when the battery
voltage becomes too low for reliable operation. For proper function of these features, the Battery Type must be set correctly in
the Utility menu.. Please see “Setting the Battery Type,” which
follows.
The ON key toggles instrument power On and Off.
Connecting the TSG95
Connect the Pathfinder to your equipment as you would any television test signal generator. Use 75Ω coaxial cable (for video) and be
sure that the signal path is properly terminated.

Definitions
There are two phrases used in this manual that deserve a little explanation. We at Tektronix sincerely hope that these explanations do
not confuse you further.
Signal Set— The group of signals that can be selected through the
TSG95 keypad at a given time. In the preprogrammed signal sets, all
of the signals are the same video standard. You may create a “User”
signal set, however, that contains both PAL and NTSC signals assigned to the letter keys of your choice, for easy selection.
Tone Level— One of four predefined audio output amplitudes that
may be selected through the Tone menu. The levels (1 through 4) are
“named” --10, 0, +4, and +8 dBu and calibrated to those amplitudes
when the TSG95 is manufactured. Qualified personnel, with the appropriate equipment, can rename and readjust the levels between --10
and +10 dBu. See page 26 for more discussion; see the Service
manual for instructions.

four sequence “time intervals.” The IDs will appear in the order
that their numbers appear—from left to right—on the display.
5. Use the
Y / B keys to select the number of the ID to appear
during each interval. Choose the hyphen (it’s below #1) to
eliminate the interval. If you want a blank interval (that is, a time
gap between ID messages), you must create an all-blank ID to put
in that interval.
6. When the correct ID numbers occupy all four time interval positions, press a rectangular key to exit the ID menu. The cycle sequence information will be written to the instrument’s memory.
Note that the TSG95 “remembers” the ID#, not the actual
message. Therefore, if you save a new message as ID# 1, the new
message will appear the next time an ID cycle comes to a time
interval in which ID# 1 is displayed.
7. To set the duration of each cycle time interval, re-enter the ID
menu (by pressing
Shift, then ID On/Off), then press the B key to
reach the CYCLE TIME menu item. Use the horizontal arrow
keys to select the duration between one and nine seconds.

Note also that while the current ID is saved, the particular messages
used in a saved cycle are not stored. Thus, if the cycle stored with a
preset “remembers” to display ID# 4 (for example), the latest message in ID# 4 will appear whenever that preset is recalled. Remember, editing an ID message can have an affect on what you get when
you recall a preset.

battery pack (Tektronix p/n 119-4488-00) in full charge/discharge
cycles. In other words, fully discharge the battery pack before recharging, and then charge the battery pack until fully charged,
approximately 16 hours. A new battery pack will take a few charge/
discharge cycles to reach full capacity.
WARNING. Install or replace batteries only with the instrument
switched OFF and the AC adapter disconnected. Failure to do so
could result in injury or death.
Replace the batteries only wit h standard AA batteries (1.2--1.5 V,
nominal), or with the optional rechargeable battery pack.
Setting the Auto Power Down (page 20) and Battery Type (page 21)
functions in the diagnostic menu also have an impact on battery life.
The battery types are disposable (Alkaline) or rechargeable (NiCad).
Setting the battery type changes the voltage thresholds for both the
BATTERY LOW display message and low-battery shutdown.
The BATTERY LOW Message
The warning “BATTERY LOW” will appear on the second line of
the TSG95 display when the battery voltage drops below a predetermined level. The level depends on the Battery Type set in the Diagnostic menu (see page 21). The TSG will operate for approximately
ten minutes after the message first appears. For best results, replace
or recharge the batteries when you first see this warning.
Low Battery Shutdown
To prevent erratic operation at very low power levels, the TSG95
will shut itself down if the battery voltage drops below a second,
lower threshold that also depends on the Battery Type setting.
Low-battery shutdown can happen with little or no warning if, for
instance, the instrument has been left on by mistake with Auto Power

Down disabled. In such cases, the TSG95 is likely to shut itself
down almost immediately the next time you switch it on. If this happens:
h Install fresh batteries or operate the instrument with the AC
adapter, and
h Confirm that the Utility menu Battery Type setting is ap-
propriate.
The shutdown threshold is higher for rechargeable batteries than for
disposable. Therefore, you will receive a false BATTERY LOW
message and may experience premature shutdown if using Alkaline
batteries when the Battery Type is set to “ rechargeable.” On the other hand, NiCad batteries may be damaged—they can lose their “rechargeability”—if they are discharged to the TSG95 threshold for
disposable batteries. Be sure to select the correct Battery Type.
Preventive M aintenance
Under average conditions, the TSG95 should receive preventive
maintenance every 2000 hours. This is approximately one year of
operation. Preventive maintenance includes cleaning, visual inspection, a performance check and, if necessary, calibration. See the Service manual for performance verification and adjustment procedures.

CAUTION. The TSG95 case is made of molded plastic. Do not allow
water to get inside any enclosed assembly or component. Do not
clean any plastic materials with organic cleaning solvents—benzene,
toluene, xylene, acetone, or similar c ompounds—because they may
damage the plastic.
