10.1.5 Test Channel Analog Output
Many of the TEST functions have an analog voltage associated with them. As a diagnostic aid it
is possible to route any one of the various test voltages out the 4th analog output port (see
Figure 2-2). Table 10-6 lists the test measurements that may be routed to test channel output. To
route an analog test measurement to test channel output, press SETUP-MORE-DIAG-ENTR and
use the PREV or NEXT buttons to scroll to the TEST CHAN OUTPUT and press ENTR. Press
the PREV or NEXT buttons to scroll to the desired measurement and press ENTR.

When a measurement other than NONE is selected, an additional test measurement appears on
the display, which has the format "TEST=XXXXX.X MV" and shows the mV value currently
being output to test analog output port.
