Hello Arnaud, I think there's a few things you may do to locate the source of the problem. 1 - Try operating the 3403C in DC, linear mode. This will bypass all the RMS to DC converter and the LOG

I am specifically looking to use the 54003A input modules standalone so am looking for the pinout. There are 6 pins plus a 50 ohm coaxial output.? As there is a LM308 in there next to the hybrid I

Now, I have read the entire post - I will check to see if there a diagram of the pinout Peter

I think that I have it on fiche Probe multiplexer Op Svc October 1985 rev 1 Paper part number 54300-90901 Fiche part number 54300-90801 Serial PFX 2510A 2 fiches, includes block diagrams and

I kept looking up on the LDs chips, on the Tek groups and here with a thread ( /g/HP-Agilent-Keysight-equipment/topic/24814035#msg76131 ) on the 8558. It uses the same duo for the AD

In the process of fixing 9 pcs E5071C, I have noted that at least three of them have low output power on both channels (-26 dBm on two, -31 dBm on the third).? I confirmed that the faulty component

Hi, I am closing down my father’s long-standing workshop, which specialized in tube and radio technology using components available in the 1970s and 1980s. There are hundreds of germanium diodes,

Er, yes. Thanks for that suggestion. I'm afraid such micro-surgery is a bit beyond me at my age! I think maybe these tests would be better suited to a scalar network analyzer - or just a spectrum

Hi. Just me, or is there a bit of an inconsistency on page one of that PDF? Between the text descriptions and the illustration below, regarding how to measure Low, Medium and High impedance

Digging a little deeper into the Service Manual, the output attenuator assy (& Reverse Power Protection- RPP) are quite different between the 1GHz -A and the -B, -C & -D higher frequency models. For

I suspect what you have there are RF/IF transformer(s)?with tuned primary and untuned secondary. If there is a tap on the primary, the center pin of the three pin side, it is used to feed supply

Thanks, but that is the operating and programming manual which, as I stated, does not have the information I seek. Peter

Sorry about that didn't read Peters entire post. ________________________________ Sent: Thursday, February 20, 2025 5:40 PM To: [email protected]

Nothing on Keysight, no luck with a web search.? I have the operating and programming manual but it doesn't help. What I'm really after is the pinout for the plug in modules as I would like to use

USB floppy drives do not implement a full floppy controller. I’ve never seen one that can handle other than 512 byte sectors, and or sector counts other than those used on MS-DOS 720K and 1.44MB

Hello, This is my first post here, thanks for allowing me in. I've had the chance to pick up an HP3403C True RMS voltmeter, serial 1452A03359, with options 0011 (Autoranging) and 006 (dB display). I

It runs fine under Fedora linux using WINE. -- T. Gerbic Central California

I pretty much just follow this guide: https://hugin.sourceforge.io/tutorials/scans/en.shtml Which can be confusing at times (wording is not totally clear at some points). Especially after you create
