Specifications
Table A-1 lists the specifications of the ac source. Performance specifications are warranted over the
ambient temperature range of 0 to 40
o
C. Unless otherwise noted, specifications are for a sinewave with
a resistive load at an output frequency range of 45 Hz to 1 kHz, in ac-coupled mode after a 30-minute
warmup. Refer to table A-3 for ac source operation with output frequencies from dc to 45 Hz.
