6.2 AC Measurement Configurations

Figure 6-5 shows the circuit configuration used for capacitance measurements. For the RES11A, a 1‑MΩ RKNOWN resistance and 10‑pF CKNOWN capacitance are used. The circuit creates an impedance divider; the resulting gain-vs-frequency relationship is used to calculate the parasitic capacitance in parallel with the resistor under test (in this case, RIN1). Calibration with an empty socket is performed to account for board parasitics. The ac source is swept from 100 Hz to 50 MHz.

Figure 6-6 shows the circuit configuration that is used for bandwidth measurements. The ac source is swept from 100 kHz to 500 MHz.

Figure 6-7 shows the circuit configuration used for crosstalk measurements. The ac source is swept from 100 Hz to 100 MHz.
