[HighVoltage]

Sold my MSOX3104A, then bought an MSOX6004A. Net difference: $3.5k. Picked up in person. Driving 20+ hrs on I95 is not fun. And for the first time I know there are non-free interstates.

Great, its seems you got a great deal then on the MSOx6004A

A Solatron 7060 multimeter, bargin at £60   

Very nice unit 

[GreyWoolfe]

Hello!

Finally I get my 53131a...
I wait for a Gerry OCXO and a Poland Prescaler... 

It works very well... Only.. the display is dim... 
I must test the DC-DC converter for 5.2V in filament and 43V for HI VOLTAGE.. Next week I will try it...
If not I cannot have the VFD... What a shame!! 

Regards
Manuel

Looks perfectly fine to me, I don't like really bright lights on anything, personally.

[msraya]

Thanks GreyWolfe.. I think so too...

But as it is my first 53131a I dont know if is normal dim o too dim.. It can be used however. .

Agilent E5810A LAN GPIB gateway from Taobao (about 120USD incluing EMS) 

[Hydrawerk]

hmm... I was a fan of it since it came out:



And I love it. It also have the GPIB option... Pratically brand new...

Sorry to tell you, but the rotary encoder is quite erratic on these 33210A  generators.  After some years of usage, it goes off.

A DP832 from Batronix 

Good for you.  I really like mine.  Although the numeric dial looks cool, it is pants to use though

My 33220 works well after updated to latest firmware and replaced the old rotary encoder with new one which I bought on ebay.

my first oscilloscope  Tek 2225

probes are still on order...  I don't have a known good function generator right now so I don't have a way to test its calibration, open to suggestions.  But for now I'll just start learning how to use it!

only cosmetic defect I see is hair line crack on the beam find button.  looks to have been previously glued.

The first obvious thing I see is Trace rotation needs adjusting. Simple enough, get yourself the Service manual and have a read.
As for Calibration, the first sanity check is using the Probe Cal terminal to check if the square wave it generates is ~1 KHz. They are rarely exactly 1 KHz but plenty close enough for a quick check. Best advice would be leave the scope alone unless you have good reason to doubt its accuracy. Think less of scopes as an ultimate measuring tool but more so of a way of displaying waveforms.

But for now I'll just start learning how to use it!

There is probably a trace rotation adjustment screw under the Focus knob.

Nice scope!
I guess you know you don't have to wait till your probes arrive? For low frequency, audio, etc, you can just use any old wires, with whatever kind of BNC adapter you can find. Any bit of coax with a BNC on one end, any impedance, spliced at the other end to alligator clips. Even plain wires. In the audio to few hundred KHz range, short cable impedance effects can be ignored.
With unshielded wires you'll get a few (tens to hundreds) millivolts of mains hum pickup, but it's all part of the learning experience. Have fun!

Oh, and btw. That scope, like most, has a calibration output. It's the little clip point in the bottom-center of the controls area. You can just wire it directly to the channel BNC inputs for amplitude and sweep calibration, since it is a low fundamental frequency square wave. It's also used for probe edge compensation adjustment, once you get them.

I didn't know this, thank you for the tip. I'm going to start watching the "Scopes for Dopes" video in the beginners section here soon.

Good to know, but They had replaced  it. It's fine and don't mess up with numbers at least for now...

Did you mean UT210E?

Yes I did

Not today, but a few days before I got a HP6112A. Good condition, only the meter is broken (frame of the meter) and the main filter cap is dried out.

So, I've been to the radio amatuer fest in Holice, Czech Republic. I bought these things.

A Peltier cooler, a photomultipler and support modules (HV PSU and amplifier), terminators, miscellany CPUs into my collection, terminators, a water bevel, miscellany small things and a soviet elapsed time counter with beautiful mechanics inside... does anyone have a datasheet to the last one?

[bitseeker]

...a soviet elapsed time counter with beautiful mechanics inside... does anyone have a datasheet to the last one?

That's cool. Never seen one before.

[daqq]

That's cool. Never seen one before.

To the best of my knowledge such counters were used to measure how long a system has been active (say a machine with a limited life time). There is no way to reset them I think. Another mechanism for this was this mercury based gadget:

Though they are reversible.

I'm jealous now, mine had bullshit packaging!
