DC coupled High Bandwidth passive Probe

(1/2) > >>

Andree Henkel:
Hy, I am looking for a DC coupled high Bandwidth passive Probe.

Basically the 12GHz P20B from Auburn Technology is close to what I am looking for, but I would prefer DC coupling.

Any hints?

So far I found:
Rohde & Schwarz RT-ZZ80, but I guess it is very expensive (~5 or more of the P20B, I asked for quote)
900 "PicoConnect" Series of passsive Probes by PicoTech (~2 as expensive as P20B)

tggzzz:

My definition of "high" is 100kHz, so virtually all probes will be OK.

Alternatively, replace the adjective with a number :)

Search terms "resistive divider probe" "Z0 probe".

I have several HP10020A probes, and like them :)

Andree Henkel:
Ok, more Detail of desired Probe:

Bandwidth 5GHz or above
Division 10:1 -> 450Ohm tip resistor
or Division 20:1 -> 950Ohm tip resistor
preferable DC coupled

HP54006A 6GHz.
Tek P6150 9GHz

Andree Henkel:
Ah, ok both seem to be discontinued, that´s why I didn´t find them at tek / keysight product pages.

But they are both available at used test equipment vendors.
