Would anyone have a Tektronix 011-0069-02 attenuator for sale at a reasonable price? I see them online for over $60 with shipping, but that is a bit too spendy for my pocket.

Hi Dale,
I have no idea from your post what it is since I don't have any way to find
out more about this part number.
I'm sure I'm not alone.
I think you would improve your odds of getting a reply from someone who does
have one if you provided a description of what it is, what it is used in,
what it looks like, and any other details you have for it.
Also, since you mention that $60 is too much, what are you willing to pay
for one?

50 Ohm 2 watt attenuator, with a male BNC on one end, and female on the other.? Can be plugged into a scope input. The one's I've seen are about 2" long and roughly the diameter of a Sarpie marker pen.
Use Google images if for a visual.
Regards,Vern

Dale, we use Mini Circuits HAT series attenuators DC-2GHz, $10 ea, highly recommended
Better than the old TEK parts.

I have some of what is available online but seldom use them as I own about 75% of the Tek catalogs from 1970 to 1993 in print. For those unfamiliar with the Tek line of external attenuators and terminations, most of which were in production in the '70s, '80s, and '90s, see the selection guide to some of them at: I was asking about the 011-0069-02 because my other Tek attenuators are the -02 versions, but the -01 or -03 version would do as well for my purposes. The 011-0069-02 is a 50 Ohm, 2 Watt, 6dB fixed attenuator with male and female BNC connectors for in-line use. It has a VSWR of <1.1 from DC to 1 GHz and <1.2 from DC to 2 GHz. It is a stand-alone accessory and not used in anything. Also, since you mention that $60 is too much, what are you willing to pay
for one? I think $30.00 would be reasonable plus CONUS USPS first class postage. It is about 2-1/2" long, 3/4" wide, and weighs about 4 oz. -- Dale H. Cook, GR/HP/Tek Collector, Roanoke/Lynchburg, VA

Better than the old TEK parts. I sometimes use my Mini Circuits CAT series attenuators in 6, 10, and 20 dB, but I prefer the Tek attenuators, and most of my fixed in-line attenuators are Tek or GR using BNC or GR 874 connectors. For my purposes the Tek is ideal, as well as matching other Tek BNC attenuators and terminations that I own. -- Dale H. Cook, GR/HP/Tek Collector, Roanoke/Lynchburg, VA

Jean-Paul -
I would also note that the HAT-6 is only a 1 Watt attenuator, and I need a 2 Watt attenuator.

Dale I have built H pad and T pad attenuators in a small adapter box, (Pomona or Tek).
I founded that with careful resistor choice and lead dress, They are OK IF you don't need 1-2 GHz.
What's your application that needs the 2 W power?

What's your application that needs the 2 W power? Connecting a modulation monitor to certain broadcast transmitters that have higher than normal output voltages at their modulation monitor ports. I need to attenuate that output to within the rated input range of the modulation monitor. I have to build far too much for work as it is (I always have a backlog) and I can't spare time to build an attenuator. For this application I prefer to buy a Tek attenuator that a) suits my needs, and b) is from the same series as my other Tek fixed attenuators. I have a check due from a client in a few days, so if I don't find a 011-0069-0x by late week I will probably bite the bullet and buy one available online. It will be at a higher price than I would care to pay but it will be exactly what I need. -- Dale H. Cook, GR/HP/Tek Collector, Roanoke/Lynchburg, VA

The TMC GPT-750 transmitter has an output monitor connection fed by a capacitive voltage divider. It is just two capacitors, a few pF from main rf output to the monitor connector and maybe .005 uF to ground. Nominal transmitter output is 750 to 1000 watts up to 32 mc.

Tektronix wasn't anything special as an attenuator manufacturer.
The most unique thing they did was make attenuators that were
spec'd with ratings related to how they multiplied the voltage
capability of a scope's input.
So,
They would call a 6dB attenuator a X2 multiplier.
A pretty full range of examples:
----------------------------------
6 dB -> X2
7dB -> X2.5
14dB -> X5
20db -> X10
Unless you actually need the X2.5 or X5 attenuators, I would
recommend that you go to MiniCircuits and buy their appropriate
series. They are attractively priced, they like individual sales,
and they work very well.
Most importantly, they won't come to you in a previously abused form.

I agree with Dennis. Original post sounded more like a request for a favour rather than hard business proposal.
In such case even a picture would be very useful.
It makes a difference between "oh, I think I have one of them somewhere" and "I have no idea, let's read the next post - click"
Cheers

What could be more specific than a particular Tektronix part number? I asked if anyone had one for sale. The only truly relevant response is from Richard Solomon offering six items for a reasonable price, which I am considering.
