    Chapter 4 — Measurement Fundamentals Introduction Measurement fundamentals include the use of additional Spectrum Analyzer functions beyond frequency, span, amplitude and marker functions. In particular, this section focuses on resolution bandwidth, video bandwidth, sweep, and attenuator functions. Resolution Bandwidth Resolution Bandwidth is determined by the intermediate frequency (IF) filter bandwidth. The Spectrum Analyzer traces the shape of the IF filter as it tunes past a signal.

  • Page 88: Sweep Limitations

    MS2717B Preamplifier Operation The preamplifier in the MS2717B has a gain of approximately 25 dB and generally will lower the noise floor by that amount. When the preamplifier is on, input attenuation can be either 0 dB or 10 dB.

    Chapter 4 —Measurement Fundamentals 4-6 Preamplifier Operation Preamplifier Measurement Example In the section below, Figure 4-1 shows a signal with the preamplifier off. Figure 4-2 shows the same signal with the preamplifier on. Notice that when the preamplifier is turned on, the noise floor drops significantly, allowing spectral regrowth components that were lost in the noise without the preamplifier to become easily visible.
