9. MENUS
These keys open softkey menus for configuring various functions. For descriptions, see the
E8663B
Signal Generator Key Reference
.
NOTE
Some menus are optional. Refer to
for more information.
10. Help
Pressing this hardkey accesses a short description of any hardkey or softkey and, in most cases, a
listing of related remote- operation SCPI commands. There are two help modes available on the signal
generator: single and continuous. The single mode is the factory preset condition. Toggle between
single and continuous mode by pressing
Utility > Instrument Info/Help Mode > Help Mode Single Cont
.
•
In single mode, help text is provided for the next key you press without activating the key’s
function. Any key pressed afterward exits the help mode and its function is activated.
•
In continuous mode, help text is provided for each subsequent key press until you press the
Help
hardkey again or change to single mode. In addition, each key is active, meaning that the key
function is executed (except for the Preset key).
11. EXT 1 INPUT
This female BNC input connector 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 with Option 1EM, this connector is relocated to the rear
panel.
12. EXT 2 INPUT
This female BNC input connector 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 with Option 1EM, this input is relocated to the rear
panel.
