I thought I knew the S-D lineup pretty well, and yet I don't recall an instance where they used a BNC on microwaves. What model do you have? -Chuck Harris <paul666@...> wrote:

The word "limit" should not be interpreted as a fixed, discrete boundary that separates "useful" from "useless". The world is analog, so it's best to consider what is really meant in a given

Is it the 6054? Are you sure there is no SMA - BNC adapter on it? Perhaps someone modified it...

No, it's the standard 50 ohm BNC output socket. I just checked and it's actually up to 24GHz according to the front panel just above that socket. It's a Systron-Donner counter if that helps at all.

The frequency counter can't measure amplitude. Using BNC above 4 GHz causes losses due to reflection, but the frequency counter will still work even if your signal is 10dB lower. If you use BNC

Hi all, According to this site: https://www.historytools.org/products/bnc-connector-types-sizes-when-to-use-each 50 ohm BNC connectors are only good up to 4GHz and 75 ohm ones to 2GHz maximum. And yet

Gianna this is incredible!? I'm currently working on a 182T with a 8557A plug-in.? Can I be greedy and ask for a Spectrum Analyzer section for this beautiful document?

Buonasera Gianni, ho iniziato a leggere il suo lavoro, a pagina 4 mi sa che deve correggere l'unità di misura delle dimensioni , sono cm , non mm By the way, ho lavorato in HP Italia dal 1976 al 1985

Some notes from my repairs; Some of the metal film resistors used in the voltage divider/feedback circuits in the PSU and the horizontal amplifier can drift high in value, or go open. The 4-071

Thank you for doing the work on this. I was working for -hp- when the 180 came out. It was almost a world beater but not quite. I suppose I am more oriented toward "old stuff" because I am old. --

I continue with my perhaps-senseless activity of documenting old stuff. This is the draft about the 180/181 oscilloscopes: http://www.k100.biz/ebooks/180_draft.pdf Any contribution/correction welcome.

Feel free to swipe the 3048A code out of timelab.cpp if you like (which can be found in the installation directory written by the setup program at https://www.miles.io/timelab/beta.htm ). Search for

Hi Andreas. I think it might be possible to use the dual diodes and they might perform better than the single diodes with lower package capacitance? It's worth a try at least. I also have some dual

Sadly, nothing significant to report from me. I tried putting a genuine 5082-2800 diode on the curve tracer and on the VNA and it is definitely a bit better (in terms of capacitance and dynamic

Hello, I tested the 2 lamps of back lighting. I have infinity on the 2. *I think we are rather dealing with "neon" style lamps and not classical filament, which explains an infinite resistance*. (? if

Hello Paul, The manual says to use the 346B/C for the calibration which are 15dB ENR sources. It also says you can use the 346A but you need to add +10dB of gain. So a minimum of +11dB sounds normal I
