Ondrej, I have seen an intermittent problem with the Ch1 & Ch2 BNC input connectors. I think it is where the center pin connects to the PCB.It wasn't my scope but a scope at work, I don't know if they

What does your business need? Two benefits of the 485 are not having calibration constants stored in a fragile ROM, and having a proper 50ohm input (not 50ohm//15pF).

Hi Attilio, It's important to understand the limitations of a noise source used as a substitute for a tracking gen. Depending on what you plan to measure, a noise source may be just fine, or it may be

Hi Nenad, i am going to buy the NF-1000 noise generator, what do you think? Greetings to all Attilio

This is very sad news. Do you know which one of the brothers it was? Sad to hear, they have been very helpful in the past with reasonable prices and good shipping practices. I hope the business will

Hi folks, I scored 485 with few missing knobs and very blurry trace. It was for about $30 so I didn't expect much from it. I have 2445B as a main scope I rely on for my everyday work as a vintage

That is a great write up indeed! if one follows this with the instructions in the manual, it should be a piece of cake.

Some years ago, I had a very fine conversation with a picture tube designer at General Electric here in Syracuse. One phenomena that could explain the double peak you see is the electrical interface

The eBay ad is a mess but the device is decent, well worth it but won't do wonders for $20. It's a white noise source, just a plain Zener diode hooked to a wideband amplifier. Reference (average)

Thanks Toby and Barry, I'm becoming partial to Nichicon, not because I think their documentation is better, but I am becoming more familiar with it. And their capacitor series. I've found their Series

AHA! Yes PG502 is a fine unit, the back term 50 Ohm is handy. I have several, neither has ever has any problem. For scope cal, the really fast rise pulses are from PG506 and Leo Bodnar's 40 pS pulser

The 1A7A manual is on the Tekwiki site. Bob Krassa AC?JL

I have the PG502 250MHz Pulse Generator in front of me now (I also have a PG506 to look over but that is another project for another time). I guess I'll see how the unit performs with the minimum of

Regarding snap caps, the leads are bent into a crook so as to allow inserting processes to push the leads into the PCB holes and grip the cap in place until soldered. Otherwise, they're like their

Thank Brian Rick

For sure DK and Mouser carbon composition resistance are from China and poor quality We use only Allen Bradley made in USA and have a huge old stock inventory 1/4---1/2-1-2W Essential for

Jared, is this the PG502 pulse gen or PG506 calibration gen? if a CAL gen with high speed edges, I suggest to NOT change any resistance or cap in the fast pulse output section In our work, since

I have been recovering a set of Tektronix 4041 tapes that I received from Stan Griffiths in 2000 in a box with Tektronix 4051 tapes. The 4041 tapes included EZ-TEST Volume 1 and Volume 2, but the

Hi Ian, I will be very careful not to damage the first mixer of my 7L13, I thought in any case to insert a DC blocker with a blocking capacitor of 1000 pF and two diodes in anti parallel. I have some
