Chapter 3. Product description
In this chapter, the front and rear panel buttons, controls and connectors are described.
1. Front Panel buttons and connectors description
Programmable Function Generator
[Figure-1] Front Panel
1) VCF input terminal
An external voltage applied to this input causes the frequency to deviate. A + 5 Voltage applied to
the input causes a maximum frequency deviation and a –5 Volts a minimum frequency deviation.
The maximum deviation is 100:1 which is useful for external sweep and FM modulation.
2) TTL output terminal
A TTL signal level with the same frequency as displayed on the LCD is available from this terminal.
3) FUNC output terminal
The output waveform with the characteristics (amplitude, offset, etc) as displayed on the LCD is
available from this terminal

4) Rotary dial
The rotary dial when turned moves the cursor position on the LCD between the menu items and is
used to select waveforms, set the output amplitude, symmetry, frequency and offset values. It is
also used to set the sweep rate and width and edit the setup menu.
5) [FRQ] Button
This Button when pressed moves the cursor to indicate the frequency value.
6) Button
(1) Toggles the cursor between the selection mode cursor displayed as a (< or >) symbol and the
edit mode cursor displayed as a (◄or ►) symbol when changing waveforms, amplitude, offset
values or sweep settings on the display or in the setup menu.
(2) When the edit mode cursor is displayed (◄or ►) and numerical data is being edited, rotating the
rotary dial, changes the cursor symbol to a (gh) symbol indicating the digit selection mode and a
digit is highlighted. Pressing the Button again the cursor changes to a (v) symbol indicating
the digit edit cursor mode. Rotating the rotary dial changes the digit value.
7) [AMP] Button
Pressing this button moves the cursor to the waveform amplitude setting on the LCD
8) [EDIT] Button
Displays the cursor in the setup or Equipment menus for editing generator settings and data values.
9) [OFS] Button:
Moves the cursor to indicate the Offset voltage setting on the LCD.
10) [SYM] Button
Moves the cursor to indicate the waveform symmetry setting on the LCD.
