Notes:
1. 2.2V Range, 100 kHz-1.2 MHz only: uncertainty specifications cover
loads to 10 mA or 1000 pF. For higher loads, load regulation is
added.
2. The 5725A will drive up to 1000 pF of load capacitance. Uncertainty
specifications include loads to 300 pF and 150 pF as shown under
"Load Limits." For capacitance’s up to the maximum of 1000 pF, add
"Load Regulation."
