8. Trigger

This key 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 E8257D/67D PSG Signal Generators Key Reference.

10. Help

Pressing this hardkey causes a short description of any hardkey or softkey to be displayed and, in most cases, a listing of related remote- operation SCPI commands. 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 (functional only with Options UNT, UNU, or UNW) accepts a ±1 Vp signal for AM, FM, and ΦM. For these modulations, ±1 Vp produces the indicated deviation or depth. When ac- coupled inputs are selected for AM, FM, or ΦM and the peak input voltage differs from 1 Vp by more than 3 percent, the HI/LO display annunciators light. The input impedance is selectable as either 50 or 600 ohms; the damage levels are 5 Vrms and 10 Vp. On signal generators with Option 1EM, this connector is located on the rear panel.
