[Bought] WTB: 33120-80001 Opt. 001 Phase-Lock Assem for Agilent 33120A Func Gen

[jeraymond]

Update: I was able to source the item.

Looking for 33120-80001 Opt. 001 Phase-Lock Assembly for an Agilent 33120A Function/Arbitrary Waveform Generator. These seem scarce. Nada on eBay or anywhere else I could find.

If you have a dead 33120A that you could pull Opt. 001 out of or one lying around otherwise, I'm willing to buy.

same instrument here. could potentially make 001 PCB. but at the moment cant find original VCTCXO datasheet

[jeraymond]

I think this might be the datasheet: http://www.conwin.com/datasheets/tx/tx006.pdf

The service guide describes it as CLK-OSC-XTAL PRC 40.000-MHZ 0.0001% with Mfr. Part Number HTV1611 from Connor-Winfield Corp.

What do you think?

What about this one ?

https://www.sglabs.it/en/product.php?s=hp-agilent-33120a-opt-001&id=1504

Probably not that cheap, but a trustworthy company.

I saw that one too, contacted them but they are sold out.

most distributors sell SMD 3.3V parts. maybe need to contact manufacturer if they can sell some parts

I had some luck finding a datasheet for the oscillator used on the board. The oscillator in the photo of the assembly from the sglabs site has markings C-MAC B1729. C-MAC sold off their frequency control division to Rakon back on 2007. I contacted Rakcon and they sent me a datasheet for the oscillator. This doesn't look like the same oscillator from the service manual, but perhaps HP sourced this part from multiple vendors.

Could be useful if someone opts to make their own version of the board. I'd be happy to collaborate with someone wishing to take on such an endeavor.

could upgrade to oven oscillator

parts list

T1-1-KK81-TR could be cheaper replacements
413990-3 need to make/get connector

What are your thoughts on an equivalent oscillator? I saw you had 40.00 € in the sheet but no link to a device.

average price on mouser, digikey... ~1ppm
