Ground connect mode
The VOLTAGE SOURCE output jack for either channel can be left floating or connected
to chassis ground by selecting the appropriate ground connect mode. When ground con-
nect is enabled, the VOLTAGE SOURCE terminal will be connected to chassis ground, as
shown in Figure 3-3. This configuration allows you to bias and measure the DUT using a
single triax cable as shown. When ground connect is disabled (Figure 3-4), you must make
separate SOURCE OUTPUT connections to the DUT. (See Section 2 for connection
details.)
NOTE The ground connect mode can be individually controlled for each channel.
