PROGRAM 2
Selects the phase angle between the external clock and the
output of the AC source. If the clock source is internal, this
parameter has no effect.
Selects internal or external clock source. The CSW Series uses
an quartz crystal time-base with an accuracy of 100 ppm. To
improve output frequency stability and accuracy, an external
clock generator may be used.
The CSW Series offers three output modes, AC, DC and
AC+DC. The VOLT MODE field can be used to toggle between
these three output modes. Both the Knob and the +/- key may
be used to toggle through these three selections. In DC mode,
no frequency selection is possible and all maximum current and
power ratings are divided by two.
When the AC+DC mode is selected, the VOLTAGE field in the
PROGRAM 1 screen is used to set the AC portion of the output
voltage. The DC OFFSET field in the PROGRAM 2 screen can
be used to set the DC offset level. Either the knob or the
decimal keypad may be used to set the DC offset level.
Selects the start phase angle for output changes made to either
voltage or frequency. This allows changing the output at a
specific phase angle. The output on key also uses this phase
angle setting to program the output voltage up to the set level
after the output relay is closed. The default value for this field is
RANDOM.
