Re: HP 8656B
I never did understand the point of the 0F13 notation and have never particular cared for it. Arbitrarily moving the units into the decimal position seems like a very random thing to do. But a

Re: HP 8656B
Late into this thread, may be misunderstanding the issue. Reads like you need a 20V 24,000uF axial cap to fit in a 104 x 28mm space on a pcb? Digi and Mouser both have a 15,000 uF axial 25V part with

Re: 8970B Noise figure unit
I have, but it was one I had already so don¡¯t remember the number. These kinds of fans are readily available, and the newer ones have a reduced noise level for the same CFM and backpressure. Peter

8970B Noise figure unit
Has anyone changed their fan on the 8970? Mine is very noisy and likely to fail soon. Original is a Dryco 411M-11, 30CFM, 115V. Kevin

Hello-- Back in the day, an introductory Electrical Engineering textbook (e.g., Hayt and Kemmerly) started off using units of basic values for examples. Hence, a circuit would contain, say, a one-Ohm
