Signal Generator Overview
Front Panel
16. RF On/Off
Pressing this hardkey toggles the operating state of the RF signal present at
the RF OUTPUT connector. Although you can set up and enable various
frequency, power, and modulation states, the RF and microwave output signal
is not present at the RF OUTPUT connector until RF On/Off is set to On. The RF
On/Off annunciator is always visible in the display to indicate whether the RF is
turned on or off.
17. Numeric Keypad
The numeric keypad consists of the 0 through 9 hardkeys, a decimal point
hardkey, and a backspace hardkey (
). The backspace hardkey enables
you to backspace or alternate between a positive and a negative value. When
specifying a negative numeric value, the negative sign must be entered prior to
entering the numeric value.
18. RF OUTPUT
This connector outputs RF and microwave signals. The nominal output
impedance is 50 ohms. The reverse–power damage levels are 0 Vdc, 0.5 watts
nominal. On signal generators with Option 1EM, this connector is located on
the rear panel. The connector type varies according to frequency option.
19. SYNC OUT
This female BNC output connector (functional only with Options UNU or UNW
or on the E8663D) outputs a synchronizing TTL–compatible pulse signal that is
nominally 50 ns wide during internal and triggered pulse modulation. The
nominal source impedance is 50 ohms. On signal generators with Option 1EM,
this connector is located on the rear panel.
20. VIDEO OUT
This female BNC output connector (functional only with Options UNU or UNW
or on the E8663D) 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 connector is located on
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.
