18. RF OUTPUT
This connector is the output for RF signals. The nominal output impedance is 50
Ω
. The
damage levels are 0 Vdc, 0.5 watts nominal.
19. PULSE SYNC OUT (PSG-A only)
This connector outputs a sychronizing TTL-compatible signal that is nominally 50 ns wide
during internal and triggered pulse modulation. The nominal source impedance is 50
Ω.
20. PULSE VIDEO OUT (PSG-A only)
This connector outputs a TTL-level compatible signal that follows the RF output envelope in
all pulse modes. The nominal source impedance is 50
Ω.
21. Line Power LED
This green LED indicates when the signal generator power switch is set to the on position.
22. Power Switch
This switch activates full power to the signal generator when set to the on position, and
deactivates all signal generator functions when in standby mode. In standby mode, the signal
generator remains connected to the line power and power is supplied to some internal circuits.
23. Standby LED
This yellow LED indicates when the signal generator power switch is set to the standby
condition.
24. Incr Set Key
This hardkey enables you to set the increment value of the current active function. When this
hardkey is pressed, the increment value of the current active function will appear in the
active entry area of the display. Use the numeric keypad, arrow hardkeys, or the knob to
adjust the increment value.
