I'm new here and I'm looking for someone to help me with my Tektronix 2465
DNS (aslo known as 2465 CTS )
I made few videos here:
about my sick scope.
Can anyone tell me where is a special group for my scope?
Thank you all for helping me and each others!
Have a great day!
Tony

I may be a little late to the game but I posted this question to a Tek

This comment/request might be a little out of scope, to calibrate a Tek
SG503 Tek says a special cable is required, Tek part 012-0482-00. This is
an extremely expensive 3 foot 50 ohm BNC cable, $200+ on ebay. There's a
discussion going on at TekScopes@... about the need for this cable
and thought this was right up your alley for a video. How do you make a
precision application cable in the home workshop? What is this cable doing
that another 3 foot 50 ohm terminated cable can't do? I'm a m addicted to
collecting Tek 500 series plugins for my home lab and have a SG503 and
would love to make one. Thanks and love your videos.

I looked up the engineering specs for that cable - doesn't look like
anything super special. 012-0482-00 refers to a 36" +/-0.5" long RG-58C/U
cable with BNC connectors and strain reliefs. The BNC connectors are to be
per MIL-C-39012 spec, which basically applies to most high-quality
(reputable manufacturer) connectors, rated to 4GHz, max insertion loss of
0.2dB at 3GHz, VSWR of 1.3:1 max with TFE insulation. Nothing super
special, just a 3' 50ohm coax made with quality materials.
