3
Connect the Micro-USB cable from the N6705C DC power analyzer to the
X8712AD RF event detector.
4
Use the test leads (not included) to connect your DUT to the output binding
post terminals of Channel 1.
5
There are two RF ports on the X8712AD. Connect the RF cable (not included)
to one of the RF ports and the other end to the back of the shield box. Connect
the 50-ohm terminator to the port not in use.
6
Connect the X8712AD RF event detector to Port 2 using
V+
and
V-
2-wire
configuration to receive analog response at the rear banana port as shown
below. The output will range from 0 to 2 V.
7
Connect the Micro-USB cable from N6705C to the front panel of X8712AD RF
event detector to power the event detector that requires 5 V of DC to operate.
NOTE
– The two in one power combiner within the X8712AD produces equal RF
signal on port 1 and port 2 on the front panel as shown on
– You are recommended to connect the 50-ohm terminator to the unused port
to avoid open reflection when you use one of the ports to measure RF power.
– The pass-through loss between port 1 and 2 is approximately 7 to 8 dB.

CAUTION
Before you turn on the output, set Channel 2 in Voltage meter (VM) mode in
KS833A1B software to prevent generating DC output to the X8712AD RF
event detector.
