Increasing the parasitic capacitance or inductance in the input paths may
introduce a “ring” or slow the rise time of fast signals. Input leads which form a
large loop area will pick up any radiated electromagnetic field which passes
through the loop and may induce noise into the probe input.
Using one of the available accessories makes the SAP2500 probe with its
small profile and low mass head ideally suited for applications in dense
circuitry.
The amplifier inside the probe has a limited linear working range. In order to
ensure that the input linearity error is less than 3%, the amplitude of the input
signal needs to be limited to ±8 V. The probe has a DC offset adjustment
function, which can adjust the DC offset to eliminate the DC component in the
test signal and maximize the performance of the probe. The DC offset
adjustment range is ±12 V.
