When I get some labels on them, I will send some
photographs. I will also send a photograph of the 4285A, as
the photo of the 4284A could confuse someone into thinking
you need the opens and shorts for cable compensation
of the 4284A, which you do not.? The two instruments look
identical though.
The 4284A, all the lower frequency
models and the higher frequency 4295A need opens and shorts
for fixture compensation. But they are quite simple. Only the
4285A needs the additional ones I made, which is for cable
compensation. On of the lower frequency models, you just set
the cable length. I expect that's good enough for use to 1
MHz, but on the 30 MHz 4285A, which two stages of compensation
are needed.
