Reply here if interested and I'll pass your message on.We have a couple of HP 141T series spectrum analysers to be sold for Farnham club funds. Both have the 8555 18GHz harmonic mixer plug in (18GHz with the internal mixer, 43GHz with an external mixer if you can find one). There is also one extra 8555 plug in which can be sold seperately if someone has a 1200MHz plug in and wants to upgrade. I've tested them all up to 2.7GHz which is where my signal generator runs out!
We're looking for offers around £200 each.
