Does anybody know what the circuit symbol for spectrum analyzer is? My internet searches for it haven't turned up anything so far. Most of the searches ended up showing the internal circuit diagram for spectrum analyzer.

Thanks.

    \$\begingroup\$ A spectrum analyzer is not a component that you would use in a schematic diagram, so there's no "standard symbol" for it. In a block diagram, you would just have a rectangle with the words "spectrum analyzer" in it. What are you actually trying to do? \$\endgroup\$ – Dave Tweed Apr 26 '16 at 15:18

    \$\begingroup\$ It's a rectangle with a writing "Spectrum analyzer" on it. \$\endgroup\$ – Eugene Sh. Apr 26 '16 at 15:47
  • \$\begingroup\$ @Dave Tweed: Regarding your question about what I am trying to do. We are in the process of adding a 2D view to ElectricVLab in addition to the 3D view currently present. When the user switches to 2D view from 3D view, all the 3D models get replaced by their circuit symbols. While writing "Spectrum Analyzer" inside a rectangle appeared as an option to me, that makes it language specific. So, I have been wondering whether there is a pictorial symbol that does not use English words. \$\endgroup\$ – Victory Apr 26 '16 at 16:02

A spectrum analyzer is a sufficiently esoteric and rare (and expensive!) piece of equipment that there's no generally recognized symbol for it.

Make something up! You could use something similar to the oscilloscope symbol, but with a waveform showing a single peak, similar to what one might see if analyzing a slightly noisy sine wave.
