Tektronix supplies a DB-37 mating connector kit with Option 41 to assemble the
signal interconnection cabling. The supplied kit, provides several sizes of cable
adapter collars. Select the one fits your cable, and put it on the cable before
assembling the wiring to the connector as shown in Figure 2–16. See Table 2–1
for the connector pin assignments. The connector pin locations are shown in
Figure 2–17. The Tektronix part number for the DB-37 connector is
200-3947-00.

After assembling the connector and checking out the wiring, install the EMI
reduction ferrite choke.
The EMI reduction parts consist of two ferrite forms and two cable tie wraps to
secure the ferrite forms on a multiconductor cable. The ferrite forms fit together
on a cable that has an outside diameter of 0.5 inch or less. The ferrite choke
consists of the following parts:
Ferrite forms, 2 ea., Tektronix part number 274-0832-00
Cable tie wraps, 2 ea., Tektronix part number 344-0120-00
When installed as described on the assembled audio cable, the ferrite forms act
as a choke to reduce the level of high-frequency noise emitted from the signal
interconnection cabling.
