Single Conditioning


Sampling Modes:

  • Asynchronous
  • Synchronous


Frequency Range:

1 Hz to 20 kHz


Resolution:

  • A/D Conversion: 24 bits
  • Dynamic Range: <80dBfs (0.01% fs), -90dBfs (typical)
  • FFT Lines / Waveform block size
    • 100 / 256
    • 200 / 512
    • 400 / 1024
    • 800 / 2048


Amplitude Range:

Dependent on sensitivity


Integration:

Two levels provided, first in hardware, second in firmware


Averaging:

Any number of averages may be specified. If sampling mode is:

  • Asynchronous: Averaging will be done on the spectra.
  • Synchronous: Averaging will be performed on the time waveforms.


Low Pass Filters:

Independently configured per channel

  • Spectra FMAX: 10 Hz - 20 kHz
  • gSE Spectra FMAX: 10Hz – 5 kHz
  • Optional Overall measurement LP filter: 200 Hz - 20 kHz, Roll Off: -24 dB per octave


High Pass Filters:

Independently configured per channel

  • Integration OFF: 1, 5, 10, 40, 1000 Hz, Roll Off: -30 dB per octave for the 1 Hz HPF, otherwise -24 dB per octave
  • Integration ON: 5, 10, 40, 1000 Hz, Roll Off:
    • Single Integration: -30 dB per octave for the 5 Hz HPF, otherwise -24 dB per octave
    • Double Integration: -42 dB per octave for the 5 Hz HPF, otherwise -24 dB per octave
  • gSE High Pass Filter: 200, 500, 1000, 2000, 5000 Hz, Roll Off: -12dB/octave
