6. Number Keys
Those keys, including numbers from 0 to 9, radix points ".", symbol keys "+/-", are
used to input parameters. Pay attention: when you need to input a negative, you
should input a symbol "-" before you input the numbers.
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. Channel Control/Output Key
Output This key is used to turn on/off Channel output.
BNC connector and its nominal output impedance is 50Ω
When turn on Output (backlight is light), the connector output waveform with
current scheme.
10. Trigger Control/Output Key
Trigger This key is used to generate a manual trigger signal in the burst mode.
This BNC connector is the Sweep/Burst trigger signal input port of external
trigger.
11. Mode/Utility Function Keys
Mod This key is used to output modulated waveforms and provide several
kinds of mode modulate and digital modulate manners. It generates AM,
AM-DSB, FM, PM, ASK, FSK and PWM modulated signals.
It supports Internal modulate source.
The corresponding key backlight lights will turn on when this function is
selected.
Sweep This key is used to generate "sine waveform", "square waveform",
"sawtooth waveform" and "arbitrary waveform" sweep signals.
It supports "Linear" and "Log" two kinds of sweep manners.
It supports "Internal" , "Manual" and "External" three kinds of trigger source.
The corresponding key backlight lights will turn on when this function is selected.
