Kit Description
This kit includes parts and instructions to upgrade a standard TDS Series
instrument with Option 05, Video Trigger.
The TDSXF05 Video Trigger kit gives you a variety of tools for investigating
events that occur when a video signal generates a horizontal or vertical sync
pulse. The tools allow you to investigate a range of NTSC, PAL, SECAM and
high definition TV signals. To make one of these kits work, you must have the
Video Trigger hardware (provided in the kit) installed in a TDS Series oscilloscope.

3. Connect the appropriate power ribbon cables (provided in this kit). The two
(2) ribbon cables interconnect to the analog power and digital power to the
Acquisition circuit board, Processor circuit board, and TV Trigger circuit
board.
4. Install the appropriate A14 D1-BUS board (provided in this kit).
NOTE. When plugging in the D1-BUS boards (see figure 3) make sure that they
remain plugged in on both ends after the kit is installed.
5. Install the Option Connector circuit board A27 (provided in this kit).
Carefully connect the bottom of the Option Connector circuit board to J39
on the Processor circuit board. Then connect the top of the Option Connector
to J1 on the TV Trigger circuit board.
6. Plug the sma connector of the 50 coaxial video cable (provided in this kit)
to J6 on the TV Trigger circuit board A29. Connect the petola end of the
cable to J1500 on the Acquisition circuit board. See Figure 4 for the
appropriate video cable routing.
7. Set the slide switch located on the TV Trigger circuit board to the following
position (see Figure 3):
a. Position A (BTL trigger IC) TDS 500B, TDS 684A, TDS 600B, and
TDS 700A and later instruments.
b. Position B (CTL trigger IC) TDS 500A and TDS 600A, except the
TDS 684A.

Installation Instructions
Attenuator Electrical Contacts Installation
Equipment required One screwdriver with a size T-15 Torx tip.
TDS 500A and TDS 600A instruments (except TDS 684A) require electrical
contacts to be installed on the Attenuator circuit board.
NOTE. Examine the attenuator section located towards the front panel on the
bottom side of the oscilloscope. If the attenuators are located on a separate
circuit board assembly, perform the following procedure (see Figure 5).
1. Remove and discard the second and fourth screw and washer assemblies
from the Attenuator Circuit board using a T-15 Torxdriver. The screws and
washer assemblies are located nearest to the Acquisition circuit board.
2. Using the 8-32 nuts (provided in this kit) as spacers, place the nuts on
mounting holes just vacated by the T-15 screws just removed. The 8-32 nuts
are used as spacers.
CAUTION. To ensure proper operation of the new video trigger upgrade the
electrical contact clip must be in contact with the the cabinet when reassembled.
Make sure the electrical contact clip is position correctly. The small tab near the
mounting clip hole should be facing up and towards the Acquisition circuit
board.
3. Place the electrical contacts, clips (provided in this kit) on top of the nuts.
Secure the clips to the Attenuator circuit board by using the 6-32 x
0.500 inch panhead T-15 screws (provided in this kit).

Execute Diagnostics
Executing Extended
Diagnostics Routine
To ensure the Video Trigger is working correctly, perform the Diagnostics
procedure.
Prerequisites: Power on the oscilloscope and allow a 20 minute warm-up before
doing this procedure.
1. Press SHIFT UTILITY
Execute (main) ➞ OK Confirm Run Test (side).
2. The internal diagnostics routine checks oscilloscope functions. When
finished, the oscilloscope displays an on-screen report of any failed modules,
features, or interfaces.
