Figure 4-24: gated burst user interface
(1) In the sine wave, square wave, ramp wave, pulse wave or arbitrary waveform
interface, press the Burst function key.
(2) Press 、 、 、 or to select the waveform function. For
example, when selecting a sine wave, press
to display the waveform and
parameters, and change the parameters. For details, please refer to Output
Sine Wave on page 10.
Note: Before configuring the waveform parameters, you must first select the
channel you want to configure. Press CH1 or CH2 to select the corresponding
channel, and the corresponding channel area in the user interface will light up.
(3) Press the N Cycle/Gate softkey to switch to the gate.
(4) Press the Polarity softkey to select the gate signal “Positive” or “Negative”. The
default is positive. The gate polarity is only available in gated burst mode. The
instrument outputs a pulse train when the gate signal on the [Ext Trig/Burst/Fsk
In] connector on the rear panel is "High" or "Low".
Counter
The frequency meter measures signals in the frequency range from 100 mHz
to 200 MHz. The [10MHz In/Out/Counter] connector on the rear panel is used
by default to receive the frequency meter input signal. The frequency meter
works from the start, unless the connector is set to an external clock input or
clock output.
(1) Press the front panel Counter function key to enter the frequency meter
interface.
(2) Connect the signal to be tested to the [10MHz In/Out/Counter] connector
on the rear panel.
(3) Set the counter:
 Press the Coupling soft key to switch AC or DC to set the coupling mode of
the input signal.
 Press the Sensitivity softkey to toggle low, medium or high.
For small amplitude signals, the sensitivity is selected to be medium or high.
