Cymometer
It is a 6-digit cymometer. The cymometer can measure frequencies from 2 Hz to the full bandwidth. Only if the measured channel has triggering
signal and in Edge mode, it can measure frequency correctly. In the Single trigger mode, it is a one channel cymometer and it can only measure
the frequency of the triggering channel. In the ALT trigger mode, it is a two channel cymometer and it can measure the frequency of two
channels.
3.How to Set the Horizontal System
You can set the corresponding parameters of horizontal system in the Capture&period window (17 in
You can use Horizontal Trigger Position control bar to adjust the horizontal position of the signal in the waveform window. You can also drag the
red pointer to adjust it (3 in

4.How to Set the Trigger System
Trigger determines when VDS starts to acquire data and display waveform. Once trigger is set correctly, it can convert the unstable display to
meaningful waveform.
When VDS starts to acquire data, it will collect enough data to draw waveform on left of trigger point. VDS continues to acquire data while waiting
for trigger condition to occur. Once it detects a trigger it will acquire enough data continuously to draw the waveform on right of trigger point.
