6/2017 Low Power Spectrum Analyzer
Data Sheet
Features The MSLSA is a single chip 1/6th octave 6
band spectrum analyzer whose center frequencies
are controlled by a single master clock. The
center frequencies are set at 1.12246, 1.2599,
1.4142, 1.5874, 1.78179 and 2 (normalized).
The sample to corner is 100:1 for the 2 Hz
normalized output and 178.16:1 at the 1.122 Hz
normalized output. The MSLSA’s 1.12246 Hz
output is 55.1 kHz (Clock at 5 MHz).
Multiple MSLSA can be connected for spectrum
analysis by taking the master clock of the high
frequency filter and dividing by 2. Selectable Power Modes
