Instrument Basics: Spectrum Analyzer -- Workbench Wednesdays 15

Spectrum analyzers display signals in the frequency domain. To use one, you only need to know about four controls: reference level, center frequency, and resolution bandwidth. In this episode, see how to use a spectrum analyzer and determine the transmitting frequency of a device.

    Same here. And one of those road tests had to be a low point in the whole road test program. This video does seem like recent content, just not that road test link.

    Oops. I missed the card's text. There is either an IEEE standard or it is in the IEEE style guide that says there should be a space between the quantity and unit. I usually follow that.

     

    I only point that out beacuse I was well into my professional career before a non-technical writer pointed out I needed to add a space. They humbled me a bit by showing me in the guide (or the standard, I really can't remember which now) that says to use space. Since then, I have (almost) always put a space between the quantity and unit.

  • I was so excited to see the spectrum analyzer give away link, but my heart sunk when I saw it was 1 year ago. (I started writing this before I had watched the entire video and heard that it was reviews of the instrument featured in the video). Even if I don't have a spectrum analyzer I do really enjoy seeing how to use test gear, because it saves so much time during the labs when you're supposed to measure things and explain the readings.

     

    Nice one as always James!

     

    P.S. I had a double take seeing 50OHM in the card talking about the input impedance not being 75 ohm. Made me think of a professor that was upset with people not having a space between the value and the units.
