That's great then. I've got about a 1.2Ghz digital signal I need to analyze and can clock it down for state analysis. Just wanted to make sure I wasn't looking at a max of 500-600MHz even in timing

Hi Emst Yes I have a spare removable fuse carrier and am in the UK. ?I also have a 437B and have checked that the 432A fuse does fit it. Please send me your address to G6HIG at Yahoo dot com. 73

Ernst, If you will send me your address I’ll send you a fuse cap. Are you good in qrz.com? 73, Dave W6TE Sent: Thursday, April 18, 2019 9:29 AM To: [email protected] Subject:

As far as I know, the card does digital. Glitch catching may be at a lower frequency because of the need for additional clocks and data patterns. The data goes into a comparator, and is then stored.

Including aliasing effects? Peter

Does anyone have the? two disk configuration files for HP E2433-60010 Training Kit for HP Logic Analyzers, preferably for the 16500.

Assuming "perfect" probing? I'm trying to be clear on the capabilities of the card as a starting point. Sent from my Samsung Galaxy smartphone.

How the instrument is set up is important. A surprising number of engineers I’ve run into in companies don’t understand how to set up a logic analyzer. Peter

That's what I'm trying to determine, if the 1-4Ghz is talking analog sampling or digital sampling. What is the maximum digital signal speed (i.e. 1's and 0's) I can expect the card to be able to

Yeah, if someone wanted to sample in timing mode a signal that was switching at a 4GHz rate that wouldn't work, if that was what the original question was. It wasn't clear what the digital vs. analog

Yes exactly. Peter

That's the difference between timing and state analysis on this card. Timing is internal asynchronous clock and state is external synchronous clock. Sent from my Samsung Galaxy smartphone.

Ernst, Send me your address and I’ll send you one. Dave

It is important if the sampling is asynchronous to a clocked signal. If synchronous, the only question is whether the analyzer can handle the clock rate, and you can go right up to it. Peter

A 16517A / 16518A isn't an scope, there is no waveform reconstruction from the signal acquisition. The output is only a 0 or 1 at each sample point.

That is what I was hoping, probing concerns not withstanding. I am curious if anyone here has successfully acquired at those speeds. Sent from my Samsung Galaxy smartphone.

Nyquist allows for capturing the highest frequency component, but not the fidelity of the waveform shape. Think of the waveform with 4 or 10 sampling dots along it and you can get an idea of what you

16700A and 16900A owner here. You'll probably get a better answer from others here, but I'll take a swing: Nyquist says 2x the signal frequency absolute minimum. My 200mhz Keysight scope samples at
