    Hi, sorry for the delay in answering.
    I have only factory manuals for both instruments.
    I can scan and send you a copy of the NTS-1000B operating manual.
    I have no detailed factory information useful to support these units.
    I have inspected and drawn up detailed block diagrams for each.
    At least, as much as possible, since the NTS-1000 gets rather difficult.
    I can send you copies as PDFs if you wish.
    I have thrown a pretty large net looking for info on these machines and have mostly come up empty.
    It is a shame to let these useful units die off simply to due neglect.

    I'm also interested in those PDFs. Please send if not too difficult.

    Hi I just bought a NTS-1000B. Can you send me a copy of the operation manual as well ? (PDF) I ask myself if there was a programing manual for this, since it has a GPIB conector, or is this part of the user manual

    thank you
    Bernd

    Did you get this manual? I am extremely interested in a pdf of it.
    thank you very much

    I have the DCR-14000A user manual in paper format, but
    nothing on NTS-1000B.

    I would like to get a copy of DCR-14000A

    I was the designer of the NTS-1000 in 1994,and just came across this post. Glad to see that people are still using these. I don't have the original drawings but could possibly answer any questions.

    Hi.
    We just bought a NTS-1000B and a DCR-2500A, but it difficult to find user manuals. Could you please send me a copy of the operation manual(PDF) for DCR-14000A as well? My e-mail address: wanghan9603@foxmail.com.
    sincere thanks to you
    Paul

    Hi there,

    I have just acquired an RDL NTS-1000A and it will be shipped here soon. I would really appreciate if someone can email me a copy of any documentation (user's manual, any other notes etc) - would like to figure out how to operate and use it (even a copy of other similar models, like NTS-1000B would be greatly appreciated!)

    Thanks a lot,

    Hi,

    I am a new owner of an NTS-1000B, but don't have any documentation etc. Could you please send me the PDF's of the operating manual, and other block diagrams of how it works etc. Basically, just looking for as much info as possible to understand, operate and maintain this instrument.

    Thanks a lot,

    Hi Darryl - I just acquired an NTS-1000B and trying to understand it better. Can you explain how the noise floor of NTS-1000B + DCR-14000A drops to -147db at 10kHz, whereas the noise floor of NTS-1000B is -130db at 10kHz?

    Also, what limits the noise floor of NTS-1000B to -130db? Trying to figure
    out if there is some quick way to increase the sensitivity (e.g. by changing LNA or ADC etc? Don't actually have the block diagram, so don't quite know
    how it works. Some high level explanation would be appreciated (I do understand the basics of delay-line based phase noise measurement system, per Agilent docs etc.)

    I have some signal generators that go down to < 140db at 10kHz, and would like to measure them.

    I have successfully used a frequency doubler (followed by a mixer/filter) to increase the sensitivity by 6db - will experiment with higher multipliers, down-converters etc. However, this approach limits the input frequency (to what the multiplier expects.) . e.g. I have a frequency west 30x brick, but it requires an input of 100Mhz.)


    Looking forward to your take on this. Thanks!

    PS: Do you have a copy of your paper that you wrote on this system? I saw a reference to it via google, but can't get to a PDF etc.
