ESG Family Signal Generators Front and Rear Panel
Front Panel Overview
User’s Guide 3-3
1. EXT 1 INPUT Connector
This female BNC input connector accepts a 1-V
pk
signal for FM,
Φ
M, and AM. For all these
modulations,
±
1V
pk
produces the indicated deviation or depth. When AC-coupled inputs
are selected for FM,
Φ
M, or AM, HI/LO annunciators will light if the peak input voltage
differs from 1.0 V by more than 3%. The input impedance is 50
Ω
. The damage levels are
5V
rms
and 10 V
pk
. If you configure your signal generator with Option 1EM, this input is
relocated to a rear panel, female BNC connector.
2. EXT 2 INPUT Connector
This female BNC input connector accepts a 1-V
pk
signal for FM,
Φ
M, AM, and pulse
modulation. With FM,
Φ
M, or AM,
±
1V
pk
produces the indicated deviation or depth. With
pulse modulation, +1 V is on and 0 V is off. When AC-coupled inputs are selected for FM,
Φ
M, or AM, HI/LO annunciators will light if the peak input voltage differs from 1.0 V by
more than 3%. The input impedance is 50
Ω
. The damage levels are 5 V
rms
and 10 V
pk
. If
you configure your signal generator with Option 1EM, this input is relocated to a rear
panel, female BNC connector.
3. Help Key
Press this hardkey for a short textual description of the function of the front panel
hardkeys and softkeys. Press this key again and you will be returned to normal instrument
operation.
4. Trigger Key
Press this hardkey to begin an event (such as a step or list sweep). This key must first be
selected as the method for activating an event by pressing the
Trigger Key softkey, located in
the softkey menus associated with the event.
5. LF OUTPUT Connector
This female BNC connector is the output connector for modulation signals generated by
the LF (low frequency) source function generator. You can also output signals where the
frequency and shape are set by the internal source as it is being used by a modulation. For
pulse modulation, however, the internal source is a sinewave that is later squared by the
modulator to generate the pulse squarewave.
This output is capable of driving 3.5 V
pk
into a 50Ω load. If you configure your signal
generator with Option 1EM, this input is relocated to a rear panel, female BNC connector.
6. Mod On/Off Key
This hardkey toggles all modulation signals on and off. Although you can set up and enable
various modulation states, the RF carrier is not modulated until
Mod On/Off is set to On. An
annunciator is always turned on in the display to indicate whether modulation is turned
on or off.
