The Maximum Source Level is the largest allowed source amplitude. This is limited by
the SR785 source output or the device under test input range. If the Reference Lower
Limit requires a source amplitude greater than the Maximum Source Level, then the
source amplitude is set to the Maximum Source Level. In this case, the Reference
Channel may fall below the Reference Lower Limit.
The Maximum Source Level may be changed at any time during a sweep.
Command: SMAX (?) {x}
Offset
Set the DC Offset of the Swept Sine Source [-5V..5V]. The offset resolution is 0.1 mV.
Note that the sum of the offset and Amplitude (if Auto Level Reference is off) or
Maximum Source (if Auto Level Reference is on) cannot exceed 5 V. Also, using large
offsets with small tone amplitudes will degrade the distortion performance of the sine
source.
Command: SOFF (?) {x}
