Channel to Channel Phase Match
Using different filter selections (Bessel IIR/Butterworth IIR/etc.) or different filter bandwidths results in phase mismatches between channels.
Bessel IIR, Filter frequency 20 kHz @ 200 kS/s; 10 kHz Sine wave
Channels on card 0.5 deg (0.14 μs)
GN816 Channels within mainframe 0.5 deg (0.14 μs)
Butterworth IIR, Filter frequency 20 kHz @ 200 kS/s; 10 kHz Sine wave
Channels on card 0.5 deg (0.14 μs)
GN816 Channels within mainframe 0.5 deg (0.14 μs)
Elliptic IIR, Filter frequency 20 kHz @ 200 kS/s; 10 kHz Sine wave
Channels on card 0.5 deg (0.14 μs)
GN816 Channels within mainframe 0.5 deg (0.14 μs)
GN816 channels across mainframes Defined by synchronization method used (None, IRIG, GPS, Master/Slave, PTP)
Channel to Channel Crosstalk
Channel to channel crosstalk is measured with a 50 Ω termination resistor on the input and uses sine wave signals on the channel above and
below the channel being tested. To test Channel 2, Channel 2 is terminated with 50 Ω, while Channels 1 and 3 are connected to the sine wave
generator.
