SWEEP TRIGGERING
Sweep triggering is provided for Step Frequency Sweep and
CW Power Sweep.
Auto: Triggers sweep automatically.
External: Triggers a sweep on the low to high transition of
an external TTL signal. AUX I/O connector, rear panel.
Single: Triggers, aborts, and resets a single sweep. Reset
sweep may be selected to be at the top or bottom of the
sweep.
SPECTRAL PURITY
All specifications apply at the lesser of +10 dBm output or
maximum specified leveled output power, unless otherwise
noted.
