7. Knob
It is used to increase (clockwise) or decrease (anticlockwise) current outstanding numerical value
when setting parameters.
8. Arrow Keys
When using knob to set parameters, it is used to switch the place of numerical value.
When inputting a file name, it is used to move the position of cursor.
When saving or reading files, it is used to choose a position to save a file or
choose a file to be read.
9. CH1 Control/Output Key
Output This key is used to turn on/off CH1 output.
BNC connector and its nominal output impedance is 50
Ω
When turn on Output (backlight is light), the connector output waveform
with CH1 current scheme.
10. CH2 Control/Output Key
Output This key is used to turn on/off CH2 output.
BNC connector and its nominal output impedance is 50
Ω
When turn on Output (backlight is light), the connector output waveform with CH2 current scheme.
11. Mode/Utility Function Keys
Mod
Modulate
This key is used to output modulated waveforms and provide several kinds of mode modulate and
digital modulate manners. It generates AM, FM, PM, ASK, FSK and PWM modulated signals.
-
It supports “Internal” and “External” modulate source.
-
The key backlight lights when the function key is being chosen.
