NOTE
In both power sweep and frequency sweep mode, the meter TRIG OUT to power source
TRIG IN connection is optional. If this connection was not setup previously, you need to
setup the proper Dwell time. You may choose to setup the Dwell time in the power source
step setting to cater the maximum settling time required by the power meter. However, to
achieve maximum speed in frequency sweep, this setup is recommended. Once the power
reading is settled, the meter will output a TTL signal at the TRIG OUT to the power source
TRIG IN to trigger the power source to step to the next point.
