Re: "Analogue" indication on Oled display
I would add, for those that don't know, the Arduino ecosystem is oriented towards being relatively easy and educational and such. But when performance is important, it's better to use the MCU chips

Tektronix scope bandwidth?
Way back about 1970 I was told that Tektronix rated their scope bandwidths at +/- 1 dB. Question? Is that true and if so, do they still do that? Paul, W8AEF

On Amazon, I think I've seen a transparent LCD capable of graphics, somewhere in the 20 to 30 USD range.? Putting a meter behind that might work. Harvey

Re: "Analogue" indication on Oled display
I've done some display work, and I generally find that the Arduino (at least the MEGA series) is too slow and has too little memory to be useful for involved graphics.? However, there's a U8xxxx

Re: "Analogue" indication on Oled display
@ David Holland, Thanks for the info. I took a look at your links and video - the performance from your Arduino is better than I expected. I've got some 480 x 320 display with // data input to play

Re: DC-5.5 GHz signal generator evaluation boad
Yes, there are a development board but its really expensive compared with the excellent used signal generators available. The board don¡¯t includes output leveling and attenuator. The output match is

Re: DC-5.5 GHz signal generator evaluation boad
Hi all I looked at the AD9166 datasheet ... and somebody else needs to build that for me. And whoever builds it needs to make it as easy to use as a 1970s sig gen like the 8640. Otherwise I'll keep

Re: DC-5.5 GHz signal generator evaluation boad
Hello, some time ago I started to compile an Excel-Spreadsheet with the Phase Noise parameters of various signal generators. You can find it here:

Re: DC-5.5 GHz signal generator evaluation boad
The 8640B datasheet gives "typical measured" SSB phase noise at 512MHz as -130dB/Hz at 10kHz offset. Option 002 contains an internal doubler, so the phase noise at 1024MHz would be ~6dB more, i.e.

Re: "Analogue" indication on Oled display
I had thought about moving the pointer so that its position on the display represents the absolute level and its position on the scale represents the precise level. Zooming in and out is certainly

Is the R &S actually a moving coil meter with an LCD scale - that's very nice but expensive to replicate ! MK

Re: "Analogue" indication on Oled display
Rhode & Schwarz used that technique on their URV 35 level meter, it works quite well. Regarding comments about accuracy. If the display is used for adjusting a null, sensitivity and stability are more

Re: "Analogue" indication on Oled display
Very nice Michael, As a variation that is used for "nulling" a signal, how about moving the pointer instead of the scale (like a mechanical meter), but dynamically adjust the *markings* on the scale

Suffering frequent double vision, I didn't realize at first the double print on the ribbon was not my eyes. I prefer an analog meter to see changing numbers, but that of course doesn't have either

I've done a similar, but simpler, version of this concept. I use 2 red/green bargraphs which can be mounted end-to-end with the green ends touching (or nearly so). In order to achieve decent
