Specifications
Table A-1 lists the specifications of the dc source. Specifications are warranted over the ambient
temperature range of 0 to 55 °C. Unless otherwise noted, specifications apply when measured at the rear
terminals after a 30-minute warm-up period.

For Agilent 66332A: applies in SCPI mode, with current detector set to DC. With current detector set to ACDC, accuracy is 0.2% + four times
the fixed error value. In COMPatibility mode, accuracy is 0.2% + six times the fixed error value.

For Agilent 6631B, 6632B, and 66332A (from 1 MHz to 20 MHz ) = 0.3mV/15mV;
For Agilent 6633B and 6634B (from 1 MHz to 20 MHz ) = 0.5mV/15mV

Applies at rear terminals with unit set to remote sensing and with sense terminals externally jumpered to their respective output terminals.
For units with Option 760, Normal mode transient response is as follows: < 250µs ('32B/332A); < 230µs ('33B/34B),
