20. VIDEO OUT

This female BNC output connector outputs a TTL- level compatible pulse signal that follows the
output envelope in all pulse modes. The nominal source impedance is 50 ohms. On signal generators
with Option 1EM, this output is relocated to the rear panel.

21. Incr Set

This hardkey enables you to set the increment value of the current active function. The increment
value of the current active function appears in the active entry area of the display. Use the numeric
keypad, arrow hardkeys, or the knob to adjust the increment value.

22. GATE/ PULSE/ TRIGGER INPUT

This female BNC input connector accepts an externally supplied pulse signal for use as a pulse or
trigger input. With pulse modulation, +1 V is on and 0 V is off (trigger threshold of 0.5 V with a
hysteresis of 10 percent; so 0.6 V would be on and 0.4 V would be off). The damage levels are
±5 V
and 10 V . The nominal input impedance is 50 ohms. On signal generators with Option 1EM,
rms p
this input is relocated to the rear panel.

23. Arrow Keys

These up and down arrow hardkeys are used to increase or decrease a numeric value, step through
displayed lists, or to select items in a row of a displayed list. Individual digits or characters may be
highlighted using the left and right arrow hardkeys. Once an individual digit or character is
highlighted, its value can be changed using the up and down arrow hardkeys.

24. Hold

Pressing this hardkey blanks the softkey label area and text areas on the display. Softkeys, arrow
hardkeys, the knob, the numeric keypad, and the hardkey have no effect once this hardkey is
Incr Set
pressed.

25. Return

Pressing this hardkey returns you to the softkey menu you were at previously. It enables you to step
back through the menus until you reach the first menu you selected.

26. Contrast Decrease

Pressing this hardkey causes the display background to darken.

27. Contrast Increase

Pressing this hardkey causes the display background to lighten.

28. Local

Pressing this hardkey deactivates remote operation and returns the signal generator to front- panel
control.
