Anyone got a source for the 12 pin connector for the HP Agilent 33320 series programmable step attenuators ?
Or a 3D-Printer model ?
I think I need to make a model as cables seem to be unobtainable.
Got cheap ones of ebay which work great after a bit of cleaning.
Now I want to make a small box with battery and BCD switch and some electronicsc to select attennuation.
Update: Made a crude plug from precision contact strips and a 3D printed housing. Works ok after some work with a 1.5mm drill on it.
(Free metal contact from plastic of the contact strips and sand down the thicker end in Dreml)
OpenScad:
$fn=50;
module tr(x=0, y=0, z=0, X=0, Y=0, Z=0)
{
translate([x,y,z]) rotate([X,Y,Z]) children();
}
module pin(){
cylinder(d=1, h=7.5);
cylinder(d=1.6, h=7.25);
}
difference() {
cylinder(d=9.5, h=7.5);
tr(-4.0, -4.0) cylinder(d=3, h=10);
tr(-4.0, 4.0) cylinder(d=3, h=10);
tr(5.3, z=5, Z=45) cube([3,3,10], true);
d=2;
tr(Z=45) tr(x=-d/2, y=d/2)
union(){
tr(x=0, y=0) pin();
tr(x=0, y=-d) pin();
tr(x=d, y=-d) pin();
tr(x=d, y=0) pin();
tr(x=d, y=d) pin();
tr(x=0, y=d) pin();
tr(x=-d, y=0) pin();
tr(x=-d, y=-d) pin();
tr(x=0, y=-d*2) pin();
tr(x=d, y=-d*2) pin();
tr(x=d*2, y=-d) pin();
tr(x=d*2, y=0) pin();
}
}
