For troubleshooting procedures related to the N6705 and N6781A/N6785A, refer
to the following Service Guides:
.
Can “Acquire”
waveform Under
“Trigger” mode?
Can program
obtain correct RF
waveform?
Can program
obtain correct
voltage and
current waveform?
Is data updated in
the program?

—
Check the progress spinner at top left
corner is still running and N6705C
appear “IO” occasionally.
—
If the program is still running, either
wait or close the program.
—
Ensure that sensor connected to the
correct channel according to type of
signal.
—
Change module to power supply mode
to ensure that recorded signals
corresponded to the event.
—
Use a different sensor.
—
Ensure that the X8712AD RF event
detector is connected to N6705C via
USB. Observe the LED and the red
LED is ON.
—
Verify if the RF signal is valid with a
value higher than -40 dBm.
—
Change trigger settings, such as
trigger level and set the offset to
negative (before event start).
—
Use N6705C’s front panel Scope View
to check the waveform signal level.
—
Change to other trigger event or use
“Single” mode instead of Trigger
