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.

This specification may degrade slightly when the unit is subjected to an RF field
≥
3 V/meter.

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 HP 6631B, 6632B, and 66332A (from 1 MHz to 20 MHz ) = 0.3mV/15mV;
For HP 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.
