8. Trigger

Initiates an immediate trigger event for a function such as a list, step, or ramp sweep (Option 007 only). Before this hardkey can be used to initiate a trigger event, the trigger mode must be set to Trigger Key. For

example: press the Sweep/List hardkey, then one of the following sequences of softkeys:

•More (1 of 2) > Sweep Trigger > Trigger Key

•More (1 of 2) > Point Trigger > Trigger Key

9. MENUS

These keys open softkey menus for configuring various functions. For descriptions, see the Key Reference.

10. Help

Pressing this hardkey accesses a short description of any hardkey or softkey. There are two help modes

available on the signal generator: single and continuous. The single mode is the factory preset condition. Toggle between single and continuous mode by pressing Utility > Instrument Info/Help Mode > Help Mode Single Cont.

•In single mode, help text is provided for the next key you press without activating the key’s function. Any key pressed afterward exits the help mode and its function is activated.

•In continuous mode, help text is provided for each subsequent key press until you press the Help hardkey again or change to single mode. In addition, each key is active, meaning that the key function is executed (except for the Preset key).

11. EXT 1 INPUT

This female BNC input connector (E8257C and E8267C only) accepts a ±1Vp signal for AM, FM, and Φ M. For these modulations, ±1 Vp produces the indicated deviation or depth. When ac-coupled inputs are selected for AM, FM, or Φ M and the peak input voltage differs from 1Vp by more than 3%, the HI/LO display annunciators light. The input impedance is selectable as either 50 or 600Ω; the damage levels are 5 Vrms and 10 Vp. On signal generators with Option 1EM, this connector is relocated to the a rear panel.
