modulated wave.
Modulation types include AM, FM, PM, ASK, FSK and PSK. Modulating signals include sine
wave, square wave, ramp wave, up-ramp and down-ramp.
2. Press
to conduct frequency sweep on sine wave, square wave, ramp wave, pulse
wave or arbitrary waveform.
In the frequency sweep mode, the frequency of output waveform is in constant change from the
start frequency to the stop frequency at a sweep rate.
3. Press
and it will generate burst waveform of sine wave, square wave, ramp wave,
pulse wave or arbitrary waveform.
1.6 Introduction to Digital Input
As shown in Figure 1-7, ET3325 sets of keys are on the front panel, which are numeric keypad,
left-right direction keys and knobs and confirmation/cancellation key. The following specifications
will offer you guidance on the use of digital input.
Figure 1-7 Numeric keypads, direction keys and knobs and confirmation/cancellation key
Direction keys
Switch of digits and system setup interface for menu selection. The left key is applicable to
backspace under numeric keypad input.
Knobs
Digit Alternation. Make a clockwise rotation to plus 1 and an anticlockwise ONE/10MHZ to
minus 1 if the change is within the range of 0~9.
Switch of internal waveform type, system setup interface for selection of menu and characters
input of file name.
Numeric keypad
Input the desired value directly and alter the size of parameters.
