Good Morning Mr. Smith,
Sadly, once again I am given little data.You scientists and your bloody data.
Here we go then.
Kindly assume that these experiments are all carried out by a monkey under duress.
All will be with your software version 1.12 and are with the standard procedure for crystal measurement, up to and including zooming the waveform.
Start up defaults 10M centre, 2M span, 1M start-300M stop.
The first slide please, Mrs. Coldheart.
Old hardware with eddy 0.8.0 firmware.
No problems whatsoever, Exactly as I expect it to perform.
Old hardware with radiolistener's 0.4.4 firmware.
First zoom attempt missed the mark by 500k and did not recover.
Yes the crystal was plugged in and no I wasn't distracted by something shiny.
Second zoom attempt grabbed it nicely.
Now on to the fun stuff.
New H4 hardware with Dislord's 1.0.53 firmware, with 51-101-201-301-401 data point choices.
101 data points set.
First attempt was much the same as the first with radiolistener's. I forgot to take a screenshot (because I was distracted by something shiny) and the second attempt behaved as would be expected.
401 data points set.
The waveform 'throwing a wobbly'. It's not consistent, but disforms half a dozen times throughout the zoom process.
This is where we end up after it kicks to the right at the 500Hz step.
Cursor centre set. Cur B-Cur A shows -29.
Also, it would have been helpful to know if it 1.08 zooms correctly when using the new 401 data point Nano. Indeed it does.
Also, you may want to make sure that it's not some sort of resolution problem with your new firmware/hardware. You know the original firmware firmware was 101 data points. You know the software zooms into a span of 500Hz. So you can calculate the step size. You can also calculate the step size for your new configuration. You could then test the step size to see if its acceptable. I'm sorry, but anything containing the word 'calculate' frightens the life out of me. Simple arithmetic is within my ability, but I'm still in the dark. Could you rephrase your last paragraph for a child.
Are you running the new configuration with the 401 points but then setting the software to 101No. I set the vna to whatever points I'm using, then change the software to match before linking.
1.08 would detect whatever the vna was set to and change automatically.
Or are you running the original hardware with the firmware I tested with and that behaves correctly?I refer you to my previous answers.
