Sweep Run/Hold: This submenu key toggles between continuous (run) sweep and hold sweep. In Run sweep mode, sweeps are continuous, and a sweep starts immediately after the previous sweep is completed. In Hold sweep mode, the results of the last sweep are displayed on the screen while the instrument waits for a trigger event to start a new sweep. HOLD is displayed on the right side of the screen in this mode.

Trigger Sweep: Pressing this submenu key causes the instrument to make a single sweep when the instrument is in Hold sweep mode. This key has no function when the instrument is in Run sweep mode.
