Environmental Considerations
viii SDA601 Serial Digital Analyzer User Manual

SDA601 Serial Digital Analyzer User Manual 1
Getting Started
Please read the following statements before using your new SDA601
Serial Digital Analyzer. See the rest of this section for tips on supply-
ing power, making preliminary settings, and connecting the instru-
ment.
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 SDA601 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 adapter 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 SDA601
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.

Getting Started
2SDA601 Serial Digital Analyzer User Manual
The battery type, disposable or rechargeable, must be selected using
through the Utility menu (see page 10). Failure to select the proper
battery type can result in damage to the batteries and product.
Replace the batteries only with standard AA batteries (1.2--1.5 V, nom-
inal), or the Tektronix rechargeable battery pack listed on page 45.
For more information, please contact your nearest Tektronix represen-
tative 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 SDA601 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 po-
larity. The external DC power connector is on the left side of the
instrument.
Figure 1: Opening the Battery Compartment
To install AA batteries or the battery pack, open the battery compart-
ment of the SDA601 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

Getting Started
SDA601 Serial Digital Analyzer User Manual 3
the optional battery pack, take the time to identify both contacts and
install the pack properly.
When selecting a power source for your SDA601, please remember:
HAttempting to use an improper AC adapter can cause permanent
damage to the instrument. USE AN APPROPRIATE DC POWER
SOURCE ONLY: Voltage must be between 9 and 15 VDC; the
center contact of the connector must be NEGATIVE polarity; and
open-circuit voltage must not exceed 18 VDC. For best results, use
the adapter supplied with the instrument.
HThere is no need to remove the optional NiCad battery pack for
recharging. The SDA601 will “trickle charge” the battery pack
whenever the standard AC adapter is attached and the instrument
is switched off. It can take up to 16 hours to fully charge the battery
pack. 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.
HAA batteries are not included with the instrument; buy them local-
ly. Rechargeable AA batteries may be used, but they are NOT re-
charged automatically. To recharge AA batteries, remove them
from the instrument and use an appropriate charger. For safety,
read and follow the battery charger instructions. Do NOT attempt
to recharge standard alkaline batteries.
HAfter three minutes with no key press, the LCD back light will be
dimmed to save battery charge. (This may be disabled through the
Utility/Diagnostics/Power Manage menu; see page 33.)
HTo guard against battery discharge if you forget to turn the
SDA601 off, enable Auto Power Off through the Utility/Diagnos-
tics/Power Manage menu (see page 10).
HThe SDA601 can sense low battery voltage. It will warn you when
the charge is sufficient for approximately ten more minutes of op-
eration. The instrument will shut itself down when the battery volt-
age becomes too low for reliable operation. See the Battery hints in
Appendix C, beginning on page 47.
The ON key toggles instrument power On and Off.

Getting Started
4SDA601 Serial Digital Analyzer User Manual
NOTE. If the instrument is operating with low batteries, it may turn
itself off and on. The batteries should be replaced or recharged
depending on battery types.
Connecting the SDA601
Figure 2: Connecting the SDA601
Connect the instrument as shown in Figure 2. The OPTION connector
is reserved for later versions of the instrument. Note that the SDA601
has many capabilities and features, and you may wish to gain familiar-
ity with it by first connecting it directly to a serial digital, component
video signal generator such as the Tektronix TSG601, an analog video
monitor, and—if convenient—a compact printer, such as the SeikoD-
PU 411 printer (Tektronix part number 119-4594-00), available from
Tektronix distributors and through TekDirect.
SERIAL INPUT
Connect the instrument to your system through the SERIAL INPUT
with 75 Ωcoaxial cable. Note that the SDA601 has internal, active
termination. The signal path that ends with the SDA will be properly
terminated only when the instrument is switched on.

SDA601 Serial Digital Analyzer User Manual 5
AUX Output
HLets you view the picture for convenient source identification.
HCan contain the On-screen Display (OSD; see page 8), which
shows the most recent Watch or Analyze results one page at a
time—instead of one item at a time as on the SDA601 display.
HWith Pulse Cross enabled (see page 24), lets you “see” the contents
of the vertical and horizontal interval portions of the serial video
signal.
HCan include Cursor cross hairs for convenient positioning of the
Cursors (see page 22).
HWhen Highlighting (see page 23) is turned on, can help you locate
and identify errors in the picture, or the digital encoding of the
signal.
The AUX output signal may be thought of as “pseudo video.” It is
derived from the serial input signal, converted to analog by an unfil-
tered 5-bit DAC. The signal can be the Y, R--Y, or B--Y component.
Please see page 35 for more information about the AUX output.
RS-232 Interface
Connect an ASCII, serial printer to the RS-232 connector to create
“hard copy” analysis reports, or to log errors detected during a Watch
session. See page 35 for the connector pinouts, and other necessary
communications settings. With a printer connected, you can
choose—through the Alarm menu—to have the SDA601 log every
error as it occurs, or to print a Watch report every ten seconds. This
will permit unattended monitoring of your system. See page 20 for
more information.
To test your printer connection and settings, perform a signal analysis
by pressing Analyze. Then, press Shift-Analyze. The printer should re-
spond by printing an analysis report that resembles the one shown in
Figure 3.

Figure 4 when the instrument is in Watch mode. You can control sev-
eral OSD characteristics (size, color, screen position) through the Util-
ity/OSD Setups submenu; see page 32.
Figure 4: The Default Watching OSD
The symbols on the bottom line of the OSD have the following mean-
ings:
HThe rotating line in the lower left indicates that Auto Power Off is
enabled.
HThe musical note symbol indicates that Alarms are toggled On
with the Alarm key or through the Alarm menu. This symbol can
appear even when the beeper and print errors items in the Alarm
menu are set to Off.
HThe “W” appears when the instrument is in Watch mode.
HThe reversed “E” means that an error is detected.
