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.

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 1: Initialize the 11801 Oscilloscope.
Step 2: Set the pulse generator period to 1 ys, the duration to squarewave,
and the amplitude of the squarewave to approximately 1 V.
Step 3: Select the sampling head channel.
Step 4: Set the time base to 1 ns/div.
Step 5: Touch Main Pos, and when the of Numeric Entry & Knob Res pop-
up menu appears, touch Set to Min.
Step 6: Touch the trigger icon.
Step 7: Touch Trigger Level, and then Fine in the Numeric Entry & Knob
Res pop-up menu.
