CONTROL DESCRIPTIONS

FRONT PANEL
1. Power Switch
Applies line power to the FG2C\FG3C power supply.
2. Gate Time Indicator
Gate interval indicator (the gate interval of internal counter is 0.01 second).
2a. Gate Time Selector
Press this button to change gate time when use EXTernal counter mode. The sequence is 0.01s, 0.1s, 1s, or 10s selected by
pressing this button.
3. Over Range Indicator
In the external counter mode, the indicator is illuminated when the output frequency is greater than the range selected.
4. Counter Display
Shows the external frequency via a 6 digit green display, and the internal frequency via a 5 digit green display.
5. Frequency Indicator
Indicates the current frequency value multiplier.
6. Gate Time Indicator
Flashes at the beginning of each gating interval.
7. Frequency Range Selector
Select the required frequency range by pressing the relevant push button on the panel as shown in Table 1 .

8. Function Selector
Press one of the three push buttons to select the desired output waveform.
9. Duty Function
Pull out and rotate the knob to adjust the duty cycle of the waveform.
10. TTL/CMOS Selector
When the knob is in, the BNC terminal of (20) will output a TTL compatible waveform. If the knob is out, rotating the knob
will adjust the CMOS compatible output (5 -15Vpp) at the BNC (20) terminal .
11. DC Offset Control
Pull out the knob to select any DC level of the waveform between ±10V., turn the knob clockwise to select a positive DC offset
level of the waveform and counterclockwise for a negative DC offset level of the waveform.
12. Output Amplitude Control with Attenuation Operation
Turn clockwise for MAX. output and counterclockwise for MIN output. Pull the knob out for additional 20dB output attenuation.
12a. 20dB Attenuation
Press the button to reduce the output by 20dB .
13 FREQ/SWEEP Selector and Frequency Adjustment
(Sweep On/Off): Turn clockwise the knob clockwise for MAX frequency and counterclockwise for MIN frequency. (Keep the
knob pointer within the scale range on the panel). Pull out the knob to start the auto sweep operation; the upper frequency limit
is determined by the knob position.
