(Some models do not have bandwidth limit function)
To turn on/off channels
Click to choose "CH1" or "CH2", check "On" to turn on the channel, uncheck it to turn off.
You can also click the channel switch in Channel window in left bottom. See figure below.
To invert a waveform
Waveform inverted: the displayed signal is turned 180 degrees against the phase of the earth potential.
Click to choose "CH1" or "CH2", check "Invert" to invert the waveform, uncheck it to display normally.
To set bandwidth limit
Click the button to choose the bandwidth limit (the chosen button has a
20M: Limit the channel bandwidth to 20 MHz to reduce display noise.
Fullband: Get full bandwidth.
To set channel coupling
DC: Pass both AC and DC components of the input signal.
AC: Block the DC component of the input signal.
Ground: Disconnect the input signal.
You can also click the coupling mode to switch it. See figure below.
To adjust the probe attenuation
For correct measurements, the attenuation coefficient settings in the operating menu of the Channel should always match what is on the probe
(see
1.How to Set the Probe Attenuation Coefficient
should be set to X1.
Some operations could be done in Channel window:
6.How to Measure Automatically
Click
to show Function menu, choose "Measure".
When you move the mouse over the area of measurement results,
Automatic measurement works under this function. Totally twenty kinds of measurements. At most 8 types of measurements could be displayed
on the bottom left of the screen. The oscilloscopes provide 20 parameters for auto measurement, including Vpp, Vmax, Vmin, Vtop, Vbase, Vamp,
Vavg, Vrms, Overshoot, Preshoot, Freq, Period, Rise Time, Fall Time, Delay A→B , Delay A→B ,+Width, -Width, +Duty, -Duty.
Show All: Choose channel from the list on the right side of "Show All", a pop-up window will show all the measurement values.
Add measurement: Check the channel and measurement type. Measurement results display on the bottom left. You can add 8 types at most
for each channel. If 8 types are exceeded, the former option will be canceled. The measured values of two channels can be displayed
simultaneously.
Remove measurement: Uncheck the measurement type to remove it. Click "Remove All" to remove all measurements.
(Some models do not have this function)
). If the attenuation coefficient of the probe is 1:1, the menu setting of the input channel
