Key
Control, Indicator or Connector
Function
The following are located on the front panel:
1
ALC ON Indicator
Lights red when ALC switch is ON.
2
ALC Switch
Turns ALC circuit ON when set in its upward position.
3
ALC SET Control
Allows you to set power once for entire frequency
range.
4
POWER MONITOR Meter
Shows when power set probe is set (POWER SET)
or when ALC circuit is properly adjusted (ALC SET).
5
MECHANICAL ZERO ADJUST
Allows you to adjust position of meter needle to zero
when signal generator POWER is OFF.
6
POWER SET/AUTO CAL Control
Allows you to SET POWER MONITOR meter when
ALC is not ON. Simultaneously sets ATTENUATOR
hairline. When ALC is ON, set white arrow to AUTO
CAL on front panel, and ALC SET.
7
ATTENUATOR Hairline
Shows you where to read the attenuation level on the
ATTENUATOR DIAL.
8
ATTENUATOR DIAL
Allows you to read the ATTENUATION level at the
location of the ATTENUATOR hairline.
9
R F OUTPUT Jack
Connects the signal generator output to other
equipments in a test set-up.
10
ATTENUATOR Control
Allows you to vary the attenuation level of the RF
output.
11
FREQUENCY Control
Allows you to vary the frequency across the
frequency range of the signal generator.
12
FREQUENCY MHz
Allows you to read the frequency which you set with
the FREQUENCY control.
13
FREQ VERNIER Control
Allows you to vary the frequency output over small
limits from the displayed value.
14
SQUARE WAVE RATE Control
Allows you to vary the frequency rate of the internal
square wave generator when the MODULATION
switch is in INTERNAL SQ. WAVE position.
15
EXTERNAL FM Jack
Allows you to introduce an external sine wave signal
to modulate the RF output.
