I wasn't comparing the units in detail.? For the vast majority of measurements, the cheaper one is more than adequate.? I am sure your extra money does buy some functionality but for me, I have

Re: 141T reference replacement..a cure??
A number of my antiques use neon bulbs as voltage references; it seems to be common in HP (and other?) instruments of that era. I too have read about (and experienced) SA plug-in fuses blowing because

Donald,Have you opened the connectors and inspected the connections on the 60220 cable?? From my experience this cable should also work with you 8566B. -rastro

Re: 141T reference replacement..a cure??
Ok, good question. This thread is nominally about the voltage reference in the 141T, older models, that was a gas regulator tube, that looked like an oversized NE2. It has been a very long time since

Re: Anybody got a good LCR meter that they want to sell?
Take a look here. I have had good luck with a couple of their testers. I bought this one but I bought it assembled but could not find that here. It is accurate and cheap etc.

Re: HP 8566B / 8568B bus interconnect cable
Verify your internal cable connections and contacts on both the cable end connectors and your instrument connectors. Over the years things take only so much abuse. I have had several units with both

Re: Anybody got a good LCR meter that they want to sell?
That is a good unit for not too demanding applications.? However, it's available on ebay for a lot less money.? In some cases, less than $10 shipped. I have a similar one and use it a lot. Bob

They aren't NE2's. NE2's run at about 67V, these run at about 89V. -Chuck Harris Scott McGrath scott@... [hp_agilent_equipment] wrote:

Re: Replace Neon NE-2 with Zener in 141T PSU?
There are two phenomena going on here. The reason that there is a radioisotope inserted into "neon" references, is the neon strikes at a different voltage when exposed to light, vs dark. This is an
