Re: How to Test an NE75 Neon Lamp

 

It should also light or flash when the 1421A is triggered, with the switch in normal.

The 1821A uses a similar circuit for the reset neon, but has it built into the reset switch, I had a similar problem with that, the neon was failing to light, I proved this by adding another neon in parallel, which worked fine. Fortunately I had a parts donor to repair the 1821A, as the switch is unobtainable.


To test neons I've used a current limited DC insulation tester (commonly known as a Megger in the UK), a voltmeter can be added in parallel to find the maintaining voltage, I use the 250V range on the Megger, if it doesn't light at that it's dead.
I could maybe use the Tek THS710 in parallel if I wanted to see the striking voltage too (might try this).

One of the Tek curve tracers could also be used, but I haven't got one.

As could a suitable? bench power supply, a series resistor is needed for this method.

Re: 11048C feed through termination data?

Dear All,

Volume 9 of the Radiation Laboratory Series, published in 1948, describes the development of improved versions of the N connector, particularly the introduction of PTFE beads in the design- no reference to any personal names.

Does anyone have the reference to the first report of the N connector and the BNC connector?

Regards,

Alwyn

Re: 11048C feed through termination data?

 

Jeff,

Do you have any reference to a contempary (1930's 1940's) document that mentions Neill or Concelman wth regard to the "N" and "C" connectors?
The 1945 NAVSHIPS document does not mention the C type as it was a later development. As an aside the Wikipedia entry for the C connector is very poor with no sensible references. It completely misses the main main feature of the C connector, it's ablity to handle high power pulses at altitude (low air pressure) The article also compares it to N and BNC which apart from size and being bayonet locking it shares nothing.
I have never claimed that N stands for "NAVY" nor hive I denied it. I don't know. All I suggested is that 1945 reference to the "original" N connector may have been to a navy type.

Of course I (or anyone) cannot find a pre-war reference to an N or C connector because they did not exist pre-war. I'm pretty certain the C is post war. It was used extensively for high power airborne L band pulse systems like Transponder / IFF and DME. Also popular for high voltage instrumentation. N types break down at high power and altitude because the only insulation is air. The C has PTFE with conical contact between insulators.

And if the N was named after Neill why isn't it Neill rather than N? there are other examples of full names for connectors e.g. Jones.

Typically at that time designations were fairly random for security reasons. Note the NAVSHIPS document is classified as restricted.

Robert.

Good luck with your choice/purchase,
I wholeheartedly agree. I have one NI USB and a real Agilent one, but I never use them. The NI software stack is the ultimate bloatware. GPIB to USB is very simple and totally OS-agnostic. Looks like a serial port. I Implemented the prologix command set in my adapter and it works reasonalbli well. I use the KE5FX software that I have adapted sligthly for use with my HP3852A and I also use Excel a lot, wrote some routines for my HP8905 audio analyser.

Re: How to Test an NE75 Neon Lamp

 

Hi Barry,
NE75 information is in the link below:

Breakdown is 60-90V, maintaining is 55V, design current is 0.4mA
Voltages in the circuit condition are when the light is off as it is below holding voltage (resistive divider R135/R136 further divides the voltage to ~ 45V).

If you are using a bench supply to test the bulb you need to supply above 90V (worst case) and limit the current in holding state (when voltage across the bulb is 55V) to 0.4mA with a resistor. Do not apply voltage directly without a current limiting resistor.?

Re: 11048C feed through termination data?

A couple of questions related to this matter. Is there any WW2/1940s era documentation that names Neil and Concelman as the inspiration for naming ?these connectors? I’ve looked for this information from that? timeframe on several occasions, ?but never found it, just more recent statements with no references to prior documentation. ?It’s ?pretty clear they both were involved in their design but ?explicit references? have escaped me so far.

And when did these connectors appear in the ’public domain’? Presume this was post WW2? It’s hardly surprising but there’s no reference to either type in the 1941 Amphenol catalog.

Here is some data from the web on Naming of the connectors. I guess because they were Americans, it is better for others to say, "No, its is N for Navy". However I have been a historical electro-technology guy for years, involved with museums, the MTT, a professional microwave engineer and a college professor and I cannot stress enough the SIGNIFICANT contribution Bell Labs made. Even in something as common as the coax connector. Mil Handbook 216 from the "40's would also be a good reference I would add that the first widespread usage of the N connector was NOT in Navy gear during WWII but in airborne Elint and Jammer equipment, Army Air Force. Jammer stuff! (Of which I have a fairly complete collection, also being a life member of the AoC).

Neill & Concelman should get their due.

The Navy name is laughable as the US Navy, like it British fore-bearer (spl? dont use this much), was VERY "hide-bound" rejecting radar until it was proven out, as an example. In the Naval ASB radar, which I have, they used a (I believe British derived) monstrosity for the coax connector, as it was only 200 MHz or so, so even things like UHF connectors worked! However, detecting and jamming radars such as the Wurzburg and it Giant brother at 550 MHz,needed better gear. You see the APQ-2 and APR-4 fitted with N's from the get go. I have not consulted the Rad Lab series yet (have the whole print set), but Radar detection took precedence in N connectors. Also the Harvard Lab- OSRD part 15 Countermeasure book may be a good source as was all jammer stuff.

Popular Coaxial Connector Types

N, C, BNC, TNC, and other coax series have been standardized. The popular SMA started as the BRM (for Bendix Research Miniature) in 1958, followed by SSMA, SMB, SMC, and others. The Type N connector, with a threaded coupling nut with?5/8” UNEF 24 turns per inch thread, met the need for a durable, weatherproof, higher power, and higher frequency connector. Type N was named for work by standards committee member Paul Neill of Bell Laboratories (New York City).?Originally for DC to 1 GHz, today versions are available for up to 11 and 18 GHz.?

From left, male, cable plug, and flange mounted female (jack) N connectors, showing pin and socket center contacts. (Photos:?Pasternack Enterprises.)

Neill and Carl Concelman of Amphenol jointly developed the quick-connect (bayonet coupling) BNC connector to meet the demand for smaller connectors to work with the new smaller coaxial cables. The “N” and “C” came from their initials, and “B” was either for “baby,” because of its smaller size, or for “bayonet.”??

Re: 11048C feed through termination data?

 

This is a good example of how facts can be distorted on the internet. What does the existence of this document prove? It is not SOLELY Navy. In WWII, the Army-Navy R-f Cable Coordinating Committee (its given name) was in charge of specifying and assuring compatibility of coax connectors and cables, as well as their performance. The document from the Navy radio site is not a Navy document per se, but a JOINT Army-Navy document and the result of this committee. It morphed into MIL HDBK 216 and was in effect until 1972, when RG- cables (Radio, Guide)? were superseded by MIL-17 definitions.
AT NO PLACE in ANY document, so far, has there been reference to the Neill connector as a Navy Connector.
Instead, I posit that EVERYONE at the time, knew Neill had invented it and so it was shortened to N. Same with the C connector from Concelman. What is the ALTERNATIVE definition for "C"? Cable, Cherries, Cheese, Coax. No, I think since the N predates the 1945 document by many years, that document is not the definition of it, merely a tabulation of properties and specifications for an existing product. The Bell System Journal would yield the dates and I may research this to quash the foolish "Navy" definition.
Show me in print an official document of the US government that defines the "N" connector as being "Navy" connector or give up. Your definition is anecdotal at best, and based on "what Joe told Sam" whereas we have Neill as the named inventor. I assure you, you cannot find ANY prewar document that specifies the US Navy as specifying a 1 GHz connector like the original N as "Navy", long before the "Navy" had any use for it.
BTW Nick has a great site, I see him often at hamfests.

It's a contempary (1945) description of coaxial cables and connectors. No mention of Neill or Concelman but it does refer to N and BNC series as well as BN, LN and HN. Interestingly it compares the N series to "the orginal N connector". I now wonder if this original N was the "Naval" connector.
Even more interestingly it clearly describes the BN as "Baby N" (It is a small connector with threaded coupling now completely obsolete) and the BNC as an improved BN connector with improved construction giving constant impedance hence Baby N Constant-impedance.
So while the accreditation of the N and BNC designations to Neill and Concelman may have occoured later (and Bayonet N Compact) Clearly this was not the case at the time they were introduced.
Things have obviously changed over the years.
