But it's not just filtering above the Nyquist. There are other ways a sampling digital scope can give you a wrong picture of reality. If all of these scopes ran their digitizers constantly at full

Well, that's why I have to have so many different scopes ;-)

Hi Peter, Sometimes, on an instrument that has been in storage for a long while, corrosion on the input BNC/N connector can cause for a round of strange readings... non-linear junctions, and all

If by "trust" you mean see things faster than the Nyquist limit, I fully agree. However, any competently designed DSO won't allow signals faster than the Nyquist limit into the sampling

Try looking for abnormalities on a LORAN-A pulse, for example... a few 10s of uS of 2 MHz every few 10s of mS, or a disk drive data stream abnormality. -John =================

So I'm finally getting to unpack all my gear and set up a lab again. As part of setting up my bench I am doing basic functionality checks on the instruments I intend to use. One is a

I am no fan of Sears because tgey really screwed me over on a socket set, but they do sell a pair of screwdriver sets that use hex bits. There are two bit sets and a common handle, totalling 64 bits,

You can play with sampling specs, but 40MS/sec gives a Nyquist limit of 20 MHz. IMO, you simply cannot trust what you see on the screen of a sampling scope. -John ===========

All- Hypothetically, would it be plausible to build a VNA with custom synthesizer/detectors and the 85047A test set? There seems to be plenty of room inside the box to add the other components.

It's my favorite "go take it somewhere there's no wheels" scope. I have one which someone modified, has a new case, not painted, but the same TEK hammertone metal texture (impressed on the metal), it

Capabilities aside, I prefer VFD displays over LCD any day of the week. Sent: Monday, December 31, 2012 5:37 AM To: hp_agilent_equipment@... Subject: [hp_agilent_equipment] Re: Best DVM

I have a couple of sets of 1/4" hex bits which include Pozidriv bits, but I've been unimpressed with them for the most part. They're fine for infrequent use, but I've found that the alloy is usually

I have about 25 (assorted value) of these repair attenuator glass replacements in a box someplace if I can ever find them. That I plan on getting rid of on the TEtrader group. Pete

So does anyone have any idea what the differences are between the 2703A prefix and the 3114A prefix. I know the "A" is US made from what I understand. I'm not finding anything in the docs, or just not

I don't know. It seems odd that they would have a minimum of $50 for the cheapest way to order (web based, no 'live humans') but no minimum for the more expensive way to order ('live humans'). I

If the bridge design is basically the same as others, there is coax on one side, and the other side is only wound for symmetry purposes, so it doesn't matter if there is the same coax or solid wire of

Jim, You can order it from Agilent (formerly known as Hewlett Packard). 5180-2720 is the 40 dB pad and costs $57.29 Adrian

Well a quick google showed that the 34401A is a 6.5 digit, and the 3478A is a 5.5 digit, so the reference on the 34401A will be quieter, and should age slower, also being the older instrument its
