Signal Generator Overview
Rear Panel
ANLG GND RET Analog ground return.
31. RF OUT
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 without Option 1EM, this connector is located
on the front panel. The connector type varies according to frequency option.
32. EXT 1
This female BNC input connector (functional only with Options UNT, UNU, or
UNW) accepts a
±
1 V
p
signal for AM, FM, and
Φ
M. For these modulations,
± 1 V
p
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 1 V
p
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 V
rms
and 10 V
p
. On signal generators without Option 1EM, this connector is
located on the front panel.
33. EXT 2
This female BNC input connector (functional only with Options UNT, UNU, or
UNW) accepts a ± 1 V
p
signal for AM, FM, and Φ M. With AM, FM, or Φ M, ± 1 V
p
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 1 V
p
by
more than 3 percent, the HI/LO annunciators light on the display. The input
impedance is selectable as either 50 or 600 ohms and damage levels are
5 V
rms
and 10 V
p
. On signal generators without Option 1EM, this connector is
located on the front panel.
34. PULSE SYNC OUT
This female BNC output connector (functional only with Options UNU or UNW)
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 without Option 1EM, this
connector is located on the front panel.
35. PULSE VIDEO OUT
This female BNC output connector (functional only with Options UNU or UNW)
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 without Option 1EM, this connector is located on the front rear
panel.
