The choice of the frequency range also affects the accuracy of the impedance measurement. This relation is shown schematically for one measurement.
Relation between the precision setting and the measurement time or the measurement accuracy
Overview of the different range and precision settings --'? rg????'? his "? to?'? ??n schematically for one measurement.
All specifications refer to measurements done with a Sciospec ISX-5 in combination with the Sciospec MEArack. The signal amplitude is set to 100mV and the frequency range to ?<10MHz“. Measurements done, using the BNC connectors show very similar results.
