3.10.2.4 Channel-to-channel crosstalk
The crosstalk specifications consider only the worst case where one analog input channel is shorted
and a sinusoidal signal of 600 V is applied between the shorted channel and the black banana-sockets
of all other analog inputs.
Range Signal frequency Typical crosstalk
10 mV 70 Hz -146 dB
500 Hz -129 dB
100 mV 70 Hz -147 dB
500 Hz -131 dB
1 V 70 Hz -143 dB
500 Hz -127 dB
10 V 70 Hz -125 dB
500 Hz -109 dB
100 V 70 Hz -107 dB
500 Hz -91 dB
600 V 70 Hz -86 dB
500 Hz -69 dB
3.10.2.5 Crosstalk from current outputs
The measurement results may be influenced by magnetic coupling from the current outputs inside the
device. For frequencies up to 70 Hz, this influence is negligible. With increasing frequency, however, a
change of the measurement values can be observed. The specifications stated below were
determined with the current outputs shorted and set to 10 A with symmetrical conditions.
Range Current output frequency Typ. coupled RMS voltage
10 mV 1 kHz 30 µV
100 mV 1 kHz 30 µV
1 V 1 kHz 48 µV
10 V 1 kHz 120 µV
100 V 1 kHz 2.4 mV
600 V 1 kHz 10 mV
