I've got a Tektronix 321 scope [serial number 001917] that I need to run from an external | |||
DC supply. The problem is, I have only the line cord, and not the | |||
DC cord. The power input plugs on the scope are obviously | |||
custom, long predating the standard IEC plug everyone uses | |||
today. | |||
So I improvised. The pin spacing for the 3-pin DC input plug is | |||
very close to the spacing of Molex 6, 9 and 12-pin plugs, and the | |||
pin diameter is not too much larger than Molex uses. So, I | |||
picked up a 6-pin Molex housing and 3 female molex pins, and | |||
then cut the housing down to 4 pins (using my pocket knife). | |||
I used an old IEC cord for the DC input wires, with the plugs cut | |||
off both ends. I attached the wires on one end to the molex pins | |||
and pushed them into the housing, then jammed to housing down | |||
onto the Tektronix connector (this flared the female Molex pins | |||
to fit the Tektronix pins. The other end of the DC power cord got | |||
banana plugs to fit the output posts of my DC power supply. | |||
The net result works fine, plugs and unplugs nicely, and unlike | |||
other power supply solutions I've seen, involves no changes to | |||
the scope. | |||
