RDL NTS-1000 phase noise testers (2026 Update)

Please email me a copy of any and all block diagrams and manuals for the series and downconverters to snipped-for-privacy@gmail.com Im a test equipment dealer and repairman. I could be of service for many types of calibration software,rare manuals etc! Thanks Paul

Hi i love the design. Minus the button covers haha. Theyre all falling off! But i have a wierd issue i think you can help troubleshoot! Above 400 mhz and at exactly 102 mhz my machine measures normal but below 350 mhz and anywhere below or above 102 mhz , my 10 hz offset to 100 hz are like -10to -30 db!!! Using an ultra low phase noise sig gen. About 40 db too high! But with my external low sig gen plugged into it at 102 mhz (the cal switched freq,its fine! And the switched cal input is fine too. Sound like a bad switch??? Thanks! Paul

Did you ever replace that batt?

I uploaded in here:

yes, it is easy, check my previous post.

No Sir, thank you for checking!

Thank you Paul.

Hi guys we have developed a schematic block diagram of the whole nts system without any manuals help and purely reverse engineering. If you want it wed love to trade your original nts manuals and or 14000a manuals . Please share to snipped-for-privacy@gmail.com Do you have any info for the pn9000 or pn9500???? Paul

Hi Paul, I am about to dig into reviving non-functional NTS-1000B and could really use any help you can provide.
