Default 50 Ohm BNC Through Termination

Needed to terminate a current probe output with a 'scope the does not provide a 50 Ohm switched input option. I can achieve this with a BNC T-piece and 50 Ohm BNC load but it gets a bit crowded around the 'scope input when selecting AC/Earth/DC etc. The Tektronix 2 Watt termination p/n 011-0049-01 or similar would be ideal.

These occasionally turn up on eBay - I have bought some. The ones made by Pomona and Emco look identical to the Tektronix ones.
Originally, I bought two 50 Ohm BNC terminations from RS at a decent price, but now I can't find them. Discontinued?

Good Luck, Colin.

I have just seen this:

https://www.ebay.co.uk/itm/50-Ohm-RF...0AAOSwrx5e~lnT

Searching the RS website for "456-150" still turned up nothing, though. It is just about identical to what I bought from RS and he has 5 at 5 each, which seems reasonable to me.
Colin.

Seems very reasonable - the RS equivalent is 2-3X that price now.

Thank you both. As it happens I have just been offered a Greenpar load by a forum member which should do the job nicely. I guess the thread can now be closed. Mike.
