To anyone with HP 8902A know-how, I just acquired a HP 8902A Measuring Receiver (SN 2834A) that was clearly dropped by FedEx during transport, most likely by the customs inspectors. The lower back

Does anybody have a knowledge of what the inside of the 8340B SYTM looks like or what components are around the PIN diode? Pictures would be helpful if anybody has taken theirs apart for fun. The

Hi from the manual of the probe , you can see that the adpater 11880A to N , is made to provide a 50 ohm termination. Regards Maurizio IZ1MDJ

After 5 years of non-use, the HP 8713B does not start and after switching on only the display and the LED on the CPU board flicker. In stand-by mode, the green and red LEDs light up, which is normal.

I'm actually surprised you could still get that mouldy oldie going in a 64-bit PC VM. There's probably the case to made for keeping an older 32-bit Lenovo/IBM Thin Client or laptop around for these

Hello HP fans, I was tinkering with my HP 85024A and some unexpected measurements made me to question my setup. Short to the point : I use a HP11880A N Adapter to link my probe to a N socket, and the

In the distant past,I used to do a lot of business with Bay Area Circuits. Ihave looked at their pricing in the last couple of years, and it seemed ok for larger than oshpark stuff and quantitys. BobH

The auction does show the manual and it is correctly listed Looks like it is a software option for the 35660A that extends the unit with instrument basic Turns out there is another option, 35681A -

Well, HP made a 3586A/B/C Selective Level Meter. Does the manual on the auction show a photo of the manual with "35680A" printed on the cover? DaveD KC0WJN [email protected]> wrote:

Answering my own question - looks like it is the HP Instrument Basic option for the 35660A

I came across an HP manual marked 35680A on a well known auction site.? A brief search does not seem to return any hits. Anyone in the group know what it is?? Seems like it might be some sort of low

In case this is of use for others at some point Whilst I was able to install and use HP Basic 6.33 on machines with recent 64-bit operating systems, I was not able to save programs in a windows

Hi Georges, I have a HP8595E with a problem of power supply. The power supply doesn't start when the line switch is on, all the power-supply LEDs remain off. I check the shematic diagram and i find a

Hi Anders, That's a good point. I have noted Aisler. Thanks. Renaud

I used to use PCBWay, but switched to Aisler since I am in Europe. They take KiCAD files directly and prices are reasonable. For me it is an ethical issue as well. Greater chance that EU suppliers pay

I would blame the switch. Over the years, I have found front/rear selector switch problems on most of my higher resolution DMMs that have that feature, and I have deleted it where possible. If you

Hi all, I hadn't used my HP33401 on 4 wire mode in years and I suddenly needed it to measure some current shunts when I noticed an issue. On 4 wire mode, with the leads shorted, on 6 digit mode, it

My boards are about 150x150mm and about 100x200mm or so, and so OSH Park is out of the question (price would be prohibitive, and worse, no volume discount...). For small projects, though - small sized

I never send PCB orders offshore. For "work work", my customer requirements nearly always involve domestic production. For prototypes, personal projects, or other low-volume stuff I usually use OSH

I've checked the non-chinese suppliers. 4 layer PC boards, 100 mm square, (right at the price point inflexion), black, HASL.? $7.00 for the board, $4.50 or so for the color.? Shippping (DHL) roughly
