31-band Analog Style RTA
module filter performance

Mac the Scope Analog Style RTAMac the Scope Analog Style RTAMeasurement of the frequency response of two adjacent 1/3 octave, time-domain elliptical bandpass filters, used in Mac the Scope's RTA module. Adjacent frequency signal rejection is 80 dB or better just 1/3 octave away from band center. Results shown are typical of all filters. RTA filter energy bandwidths (for bands 1 to 30: 20 Hz to 16 kHz) are matched within 0.08 % (20 kHz, band #31 low pass shoulder limited to 22050 Hz). Filter plateaus are flat within 0.03 dB.

1/3 Octave RTA Accuracy
(Mac the Scope 2.6).
Mac the Scope Analog Style RTA RTA Deviation from Flat Response
  • Bands # 1 to 30 (20 Hz, 25 Hz, ... to 10 kHz, 16 kHz) accurate within 0.1 dB (noise as test signal)
  • Band # 31 (20 kHz) within 0.4 dB
  • Similar results can be expected when using pure tones
