4.1.5 Dynamic output signal balance (Figure 9)<br />
During transitions of the generator output between alternating binary states (one-zeroone-zero,<br />
etc.), the resulting imbalance of the offset voltage (V OS ) measured between<br />
the matched 49.9 Ω ±1% test load resistors (RL) to circuit common (C) as shown in<br />
Figure 9, should not vary more than 150 mV pp (peak-to-peak). Measurement<br />
equipment used for compliance testing shall provide a bandwidth of 5 GHz minimum.<br />
Scope probe shall present atleast 100 kΩ differential resistance with no more than 1 pF<br />
differential capacitance loading.<br />
