I can't speak to the 3048 but for screen captures I used to use the snipping tool, but have recently started using Irfanview.  You can run it in the background and with a single command (I use Ctrl+F11) can copy the full screen or window and save it instantly in a format and location of your cho

I don't believe there's a way to save images from within HTBasic, although there certainly should be. I use the "Snipping Tool" accessory in Windows 7 for that sort of thing. It probably exists in all versions of WIndows including 10, but who knows what they call it these days. If you crea

I am running an HP 3048 under HTBasic and I have a nice looking phase noise graph on the screen. I want to export the graph to the world outside of RMB. Using the "Hard Copy" or "Plot" function keys does nothing, probably because I don't have an HP-IB printer or plotter connected. (I actually h

Hi Bob, It's not all that odd, we know why, but getting sufficient control over manufacturing cost more than means to overcome it by other aspects of design. The wall-shift, the exact composition of gases and the pull of the cavity is known features of any gas-cell. The drawbacks however all

Hi One of the odd things about typical Rb standards is that the cells come out of manufacturing with a “spread” of frequencies. The more of the spread you can use, the fewer cells you throw away. Today DDS based loops let manufacturers use a *lot* more cells than they could use “back in the ol

Hi, It used to be a simple division, but these days there is several different options on how to build an atomic reference and what atom to use in what setup. There is a myriad of issues under the hood, so there is many different outcomes. There is also some interesting set of products, and u

Time-nuts, I have a 100 kHz Quartz Technik crystal oscillator with matching socket. It comes from a Hartmann&Braun / Grundig frequency counter (surely it was the timebase). 1950s/60s I expect. If anybody has a use for this it's yours for the shipment cost. (Currently located in the UK). Best reg
