Crosstalk
Crosstalk between two adjacent output channels is measured with one output connected to a battery-powered
Stanford Research Systems SR560 low-noise differential preamplifier set to gain 1000 and to a
National Instruments
4071
PXI digital multimeter operated in digitizer mode for recording the spectrum, while the adjacent output is set to
1 V and 10 V output amplitude. The following settings were used for the measurement:
SC5
DMM
Measured output:
AO1
Mode of operation: Digitizer, AC Volts
Driven output:
AO2
Range:
10 V and 100 mV
Output amplitude:
1V and 10 V Samplig rate:
5 kS/s
