TDS3SDI 601 Digital Video Technical Reference 1
Getting Started
This section describes how to install and check the TDS3SDI 601
Digital Video application module.
Installing the Application Module Firmware
NOTE. You must do the firmware installation procedure the first time
you install a new application module. If you do not update the
oscilloscope firmware, the new application module may not function
at all, or may not function correctly. It is strongly recommended that
you install new firmware when the oscilloscope determines an update
is necessary.
To install the application module firmware, do these steps:
1. Save any oscilloscope settings and/or reference waveforms to
floppy disk before doing these steps.
2. Turn the oscilloscope power off.
3. If the application module came with one or more floppy disks,
insert floppy disk 1 into the floppy disk drive.
4. Power on the oscilloscope. The oscilloscope checks if a firmware
update is required. If an update is required, go to page 2. If an
update is not required, got to page 3.

Getting Started
2TDS3SDI 601 Digital Video Technical Reference
Firmware Update Required
If a firmware update is necessary, the oscilloscope displays the
following message:
“This procedure will replace the firmware in the instrument with
firmware from the floppy disk. This procedure will take
approximately 5 minutes.
Caution: Do not turn the instrument off or eject the floppy disk
until prompted.
Push ‘OK Load New Firmware’to proceed.
Push MENU OFF to abort this procedure.”
1. Push OK Load New Firmware to begin loading the firmware.
The oscilloscope shows a clock icon on the screen while loading
the firmware. If a second firmware floppy disk is required, the
oscilloscope will instruct you to eject the first disk and insert the
second disk.
If you do not want to upgrade the firmware, push MENU OFF.
When the firmware upgrade is complete, the oscilloscope will
restart automatically with the new firmware.
NOTE. If you power off the oscilloscope, eject the floppy disk before
prompted, or there is a power outage during the firmware upgrade
process, you must restart the firmware upgrade procedure starting at
step 2 on page 1.

Getting Started
TDS3SDI 601 Digital Video Technical Reference 3
2. The oscilloscope may also display the following message:
“WARNING! This instrument is not calibrated. You must run
Signal Path Compensation (SPC) in order to calibrate the
instrument.
SPC is adversely affected by input signals with AC components.
Disconnect or otherwise remove these signals prior to running
SPC. SPC will take approximately 10 minutes to run.
Push ‘OK Compensate Signal Paths’to begin the calibration
procedure. Or, you may run SPC in the UTILITY Cal menu.”
3. If the instrument has been operating for 20 minutes or longer in
the ambient temperature at which it will be used, disconnect all
signals and push OK Compensate Signal Paths to run SPC. You
can also ignore this step for now and run SPC at a later time.
4. Proceed to step 1 of Firmware Update Not Necessary (below) to
finish the installation.
Firmware Update Not Required
If a firmware update is not necessary, the oscilloscope displays
the following message:
“A floppy disk containing instrument firmware has been detected.
However, the firmware on the disk is not newer than the
instrument firmware. Therefore, no firmware upgrade is required.
Push MENU OFF to remove this message”
1. Push the MENU OFF button.
2. Eject the floppy disk.
3. You are done installing the firmware. Go to to Installing the
Application Module on page 4.

Installing the Application Module
The following figures show how to install the TDS3SDI application
module.
CAUTION. Turn off power before installing or removing a module. To
avoid damaging the oscilloscope or application module, observe the
ESD precautions described on page iv.

Checking Module Installation
Do these steps to check that the TDS3SDI 601 Digital Video
application module and firmware are correctly installed.
1. Power on the oscilloscope. Look at the oscilloscope startup
screen; it should list the 601 module. If the oscilloscope displays
a message stating that there is incompatible firmware, power off
the oscilloscope and do the steps in the Installing the Application
Module Firmware, starting at step 2 on page 1.
2. Push the QUICKMENU panel button.
3. Push the Menu bottom button to select Video.
4. Push the SUBMENU bottom button to check that it displays
SDTV/HDTV and ITU-R 601.
If the oscilloscope does not show these menu items, go to Trouble-
shooting Module Installation on page 8.
NOTE. You do not need to reinstall the firmware if you remove and
reinstall an application module. However, the features provided by
that application module are not available until you reinstall the
module.

Getting Started
8TDS3SDI 601 Digital Video Technical Reference
Troubleshooting Module Installation
If the oscilloscope does not recognize the application module at
power-up, do these steps:
1. Turn off the oscilloscope.
2. Following the ESD precautions listed on page iv, remove the
application module.
3. Examine the oscilloscope and application module contacts for
damage.
4. Reinstall the application module into the oscilloscope.
5. Reinstall the firmware (page 1).
6. Turn on the oscilloscope. If the oscilloscope still does not display
the application menu items as listed in Checking Module
Installation, power off the oscilloscope and contact the nearest
Tektronix service center.

601 Digital Video Feature Overview
This section provides an overview of the 601 Digital Video module
features.
ITU-R BT.601 Signal Conversion
The 601 Digital Video module converts serial digital video to analog
video composite and component (RGB or YPbPr) signals connected
to the oscilloscope inputs. The 601 digital video functions also
provide error detection and counting, as well as signal equalization
for remotely-connected video equipment signals (typically up to 250
meters of Belden 8281 or equivalent cable).
VideoQuickMenu
Use the video QuickMenu to display bottom and side menus that
contain commonly-used video functions useful for displaying and
measuring video signals.
Video Autoset
Use the autoset function to automatically adjust the vertical,
horizontal, and video trigger settings to display a video waveform
triggered on all lines or fields. You can then manually adjust controls
to optimize the display.
Vectorscope
Use the Vectorscope function with 100% and 75% color bars to
analyze 601 digital, standard video, or analog HDTV color
difference video signals using a familiar display format.
