3.8 Band Scan Mode
The SARK-110-ULM can be used as a rudimentary Spectrum Analyzer in Band Scan Mode. It
can be used to scan for nearby signals that may interfere with the measurements or to measure
the power of the spectrum of signals in a lab environment.
Operation is like the Scalar Mode. The sweep speed is slower than in other modes and is largely
proportional to the width of the Span setting. Narrower spans yield faster sweeps.
The SARK-110-ULM was not designed as a Spectrum Analyzer so there are a number of
limitations when used for this function, such as:
• The power level is not calibrated so the measured power levels are not necessarily
accurate.
• The input mixer has no image suppression, so on narrow spans; the image will appear
at equal amplitude.
