Similarly, after setting the master set ‘Phase Ctrl’ of the remaining two AC sources to
‘Slave’. The slaves will automatically connect to the master.
This completes the set-up process for three phase operation.
3) 3-Phase parameters and output
3-Phase parameters include: Voltage (rms), Frequency (Hz), and Phase (deg). The
reference phase of the master is always fixed at 0 degrees. The phase angle of slave
sources can be adjusted from 0 to 359.7 degrees.
The coupling mode can be changed to AC+DC in 3-phase mode to add a positive or
negative DC offset to the AC signal. The DC offset can be set from -424 V to +424 V.
Output of the system is controlled by the master. Enabling/disabling the output of the
master also enables/disables the output of slave instruments.

Table 11.2: TL983P pin definitions
The 8-pin digital I/O terminal block on the rear of the
TL983P adapter preserves commonly used signals. See
Table 11.2 for the pin definitions. To insert a wire into
the digital I/O block: press the orange tab in, insert
wire, and release the tab to hold the wire in place.
