Channel to Channel Phase Match
Using different filter selections (Wideband/Bessel IIR/Butterworth IIR/etc.) or different filter bandwidths will lead to phase mismatches between
channels.
Bessel IIR, Filter frequency 20 kHz @ 200 kS/s; 10 kHz sine wave
GN611 Channels within mainframe
Butterworth IIR, Filter frequency 50 kHz @ 200 kS/s; 10 kHz sine wave
GN611 Channels within mainframe
Elliptic IIR, Filter frequency 50 kHz @ 200 kS/s; 10 kHz sine wave
GN611 Channels within mainframe
GN611 channels across mainframes
Channel to Channel Crosstalk
Channel to channel crosstalk is measured with a 50 Ω termination resistor on the input and using sine wave signals on the channel above and
below the channel under test. To test channel 2, channel 2 is terminated with 50 Ω and channel 1 and 3 are connected to the sine wave generator.
