PRODUCT DESCRIPTION
The DL-11 Delay Line contains two independent delay lines, with a trigger pickoff on the input of each delay line.
When used with a TEKTRONIX 11801 Digital Sampling Oscilloscope, the DL-11 Delay Line allows viewing of
the trigger event (pretrigger view). The cables necessary to connect the DL-11 Delay Line to the 11801 Oscillo-
scope External Trigger and sampling head inputs are supplied with the DL-11 Delay Line.

Safety Summary
Terminology
The safety information in this summary is for both operating and servicing person-
nel. Specific warnings and cautions will be found throughout the manual where
they apply, but may not appear in this summary.
CAUTION statements in manuals identify conditions or practices that could result
in damage to the equipment or other property.
WARNING statements in manuals identify conditions or practices that could result
in personal injury or loss of life.
CAUTION on equipment means a personal injury hazard not immediately accessi-
ble as one reads the marking, or a hazard to property; including the equipment
itself.
DANGER on equipment means a personal injury hazard immediately accessible
as one reads the marking.

General Information
Connecting |
Signals
Packaging for
Shipment
The DL-11 Delay Line is a passive instrument, and does not require any power
input.
The signal connectors on the front panel of the DL-11 Delay Line are SMA con-
nectors, mechanically compatible with Precision APC 3.5.
You must attach cables to the SMA-compatible connectors carefully to prevent
damage to the cables or the connector. Do not turn the cable, only turn the nut on
the cable, and use light finger pressure initially to connect the cable. Then use a
torque wrench to tighten the connection to within the 79-112 N-cm (7-10 in-Ib)
range.
Do not over-tighten SMA-compatible connectors.
Improper tightening may cause a change in impedance.
If the DL-11 Delay Line is to be shipped for long distances by commercial trans-
portation, we recommend that it be packaged in the original manner. The carton
and packaging material in which your delay line was shipped should be saved
and used for this purpose.
Also, if the DL-11 Delay Line is to be shipped to your local Tektronix Service Cen-
ter for service or repair, attach a tag to the delay line showing the following:
= §=Owner of the delay line (with address);
= Name of person to contact at your firm;
= Complete delay line type and serial number;
m Describe the service required, or the symptoms that the delay line is exhibit-
ing.
If the original packaging is unfit for use or not available, package the delay line
as follows:
[_] Step 1: Obtaina corrugated cardboard shipping carton with a 200-pound
test strength and having inside dimensions at least six inches greater than the
delay line dimensions (refer to Specifications in this instruction sheet). This
allows for cushioning.
[ ] Step 2: Wrap the delay line with polyethylene sheeting or equivalent mate-
rial to protect the finish.
[_] Step 3: Cushion the delay line on all sides by tightly packing dunnage or
urethane foam between the carton and the delay line, allowing three inches
on each side.
[] Step 4: Seal the carton with shipping tape or with an industrial stapler.

[-] Step 5: Mark the address of the Tektronix Service Center and your return
address on the carton in one or more prominent locations.

The exploded view drawing associated with the Replaceable Parts list may be
helpful in the removal or disassembly of individual Field Replaceable Units
(FRUs).
Remove the delay line as follows:
m Step 1: Position the delay line on its rear panel, and remove the four Torx
head screws that retain the front panel.
m Step 2: Lift the front panel straight up so that you have access to the nuts of
the trigger pickoff cables.
m Step 3: Use a 5/16-inch open-end wrench to disconnect the trigger cables
from the front panel connectors, and remove the front panel.

m Step 4: To disassemble the chassis from the delay line, set the delay line
on its feet, and remove the two Torx head screws from the rear panel.
m Step5: Slide the delay line chassis out of the case.

m Step 6: Use an 11/32-inch nutdriver to remove the two washer nuts, flat
washers, and retaining clamps holding the delay line coil to the chassis.
m Step 7: Use a 5/16-inch open-end wrench to loosen the delay line nuts at
the SMA connectors, then alternate loosening the nuts with your fingers and
pulling the delay line coil away from the connectors, so that you pull the de-
lay line off smoothly.
Figure 5 — Chassis Assembly
To replace the delay line, follow Steps 1-8 in the reverse order. When attaching
the delay line to the chassis, attach the front clamp first and pull it towards the
front of the chassis while tightening the nut. Then attach the rear clamp and pull it
towards the rear of the chassis while tightening the nut. Use an open-end torque
wrench to tighten the connector nuts to 110 N-cm (10 in-Ib).

Assembly
Remove the Trigger Pickoff and Compensator assembly as follows:
m Step 1: Remove the delay line attached to the Trigger Pickoff and Compen-
sator assembly (see the delay line removal procedure).
m Step 2: Use a5/16-inch open-end wrench to remove the trigger pickoff ca-
ble from the Trigger Pickoff and Compensator assembly.
m Step 3: Remove the two Torx screws and withdraw the Trigger Pickoff and
Compensator assembly from the chassis.
To replace the Trigger Pickoff and Compensator assembly, follow Steps 1
through 3 in reverse order. Use an open-end torque wrench to tighten the connec-
tor nuts to 110 N-cm (10 in-Ib).

Information
Using the
Replaceable Parts List
This section contains a list of the components that are replaceable for the DL-11 Delay Line. As de-
scribed below, use this list to identify and order replacement parts.
Replacement parts are available from or through your local Tektronix, Inc. Service Center or repre-
sentative.
Changes to Tektronix instruments are sometimes made to accommodate improved components as
they be come available and to give you the benefit of the latest circuit improvements. Therefore,
when ordering parts, it is important to include the following information in your order:
= ~=©Part Number
= = Intrument Type or Model Number
= = Instrument Serial Number
= ~—= Instrument Modification Number, if applicable
If a part you order has been replaced with a different or improved part, your local Tektronix Service
Center or representative will contact you concerning any change in the part number.
Change information, if any, is located at the rear of this manual.
The tabular information in the Replaceable Parts List is arranged for quick retrieval. Understanding
the structure and features of the list will help you find the all the information you need for ordering
replacement parts.
Item Names
In the Replaceable Parts List, an Item Name is separated from the description by a colon (:). Be-
cause of space limitations, an Item Name may sometimes appear as incomplete. For further Item
Name identification, U.S. Federal Cataloging Handbook H6-1 can be used where possible.
Indentation System
This parts list is indented to show the relationship between items. The following example is of the
indentation system used in the Description column:
