Electrical Differences between 015-0611-00 (Tektronix) and 015-0611-01 (Tegam)


 

Hi to All,

What are the electrical differences between both Pulse Heads? Or are the differences only Mechanical? The Tegam Pulse Head I saw recently on eBay has a SMA-Output Connector instead of a BNC-Connector. And this SMA-Connector was definitely original. Anybody with some insight information?

Hi to All,

See pictures of eBay# 271093952229 of detailed pictures of this 015-0611-01 Tegam Pulse Head. Or:

Hi Egge Siert,

I think the only difference is the connector. I do have a Tektronix 015-0611-01 but it has a Tegam serial number and has an SMA connector. I also have Tektronix 015-0611-01 with a Tek s/n and it has a BNC connector. Maybe when Tegam took these over they went with an SMA connector.

With an SMA to BNC adapter hey both work exactly the same.

If my forgettery is to be trusted, the 015-0611-01 pulse head was used on the CG5010 and CG5011 (both Tektronix and Tegam), while the 015-0611-00 was used on the CG511AP. Apart from the output connectors, I believe they are identical.

Hi Dave,

You mixed indeed something. The predecessor of the 015-0611-00/01 Pulse Head is the 015-0311-00/01. This earlier model was used in combination with the CG551AP and CG5001. It only differs from the later 015-0611-00/01 in the used Relais. The 015-0611-00/01 Pulse Head enclosure is also a little higher to accommodate the new relais. Another difference is the slightly better Trr (150ps versus 200ps in case of the old design). The Lemo connector is the same and they share the same electrical circuitry (except the relais). They can indeed be mixed between all 4 CG's.

Greetings,

Egge,

Thanks for correcting my faulty recollection - I would guess that the difference in rise time is almost 100% attributable to the use of the SMA output connector.

Regards,
David Partridge

Hi Dave,

The 150ps versus 200ps difference is in my view only the result of the better RF-environment of the new relais(design) in the 015-0611-00 Pulse Head. I have both BNC Pulse Heads (311-01 and 611-00) and also their Manuals. Victor Silva has a 015-0611-01 Pulse Head. And this Tegam made one has the SMA-Connector as Output-Connector. I don't have a 015-0611-01 Manual (I can order one for you). According to Tegam's CG5011 Documentation the Trr is slightly worse (<160ps).
