Figure 44: Output to input transfer function amplitude (left) and phase (right) from 10 mHz to 100 kHz, including all
delays due to digital signal processing.
Linearity
Linearity is measured with a
National Instruments 4071
PXI digital multimeter operated in digitizer mode at 5 kS/s
connected to AO1. The sinewave has a frequency of 100 Hz and amplitudes ranging from 10 V (0 dBFS) to 10 µV (-
120 dBFS). The following settings were used for the measurement:
SC5
DMM
Measured output:
AO1
Mode of operation: Digitizer, AC volts
Output signal:
Sine wave
Range:
10 V and 100 mV
Frequency:
100 Hz
Sampling rate:
5 kS/s
Resolution:
18 bit
