With Anritsu MS2721B spectrum analyzer the supported frequency range is from 9 kHz to
7.1GHz. The sample count is fixed to 551, and RBW is adjusted automatically. RBW is
between 1 Hz - 3 MHz. It is automatically adjusted to the closest value of 1 Hz, 3 Hz, 10 Hz,
30Hz, 100 Hz ... 300 kHz, 1 MHz, 3 MHz.
15. When signal volume is lower than -50dBm, selecting the Use preamplifier functionality in
the Measurement Properties dialog can increase the scanner’s measuring sensitivity,
hence slightly decreasing background noise. However, it is recommended that it is not
selected when signal volume is higher than -50dBm.
