Software controls
Connect:
Connect the software application with the WFS210 via USB or WLAN.
Autorange:
Automatic setup for the volts/div, time/div, and trigger level to produce a
stable waveform of usable size.
Time base:
Selects the time setting for the beam to sweep one major division on the
screen. By selecting different time/div settings it is possible to zoom in on the frozen
waveform on the screen.
Trigger options
TRIGGER Channel:
Selects the trigger source signal (CH1, CH2 or EXT)
TRIGGER Edge:
Selects the triggering slope.
Arrow up: the signal will only appear when a rising slope is detected, i.e. the input
voltage is lower than the trigger level and exceeds the trigger level.
Arrow down: the signal will only appear when a falling slope is detected, i.e. the input
voltage is higher than the trigger level and must descend under the trigger level.
Normal:
A triggering must occur before the sample memory is filled. Use this mode
when you want to start displaying the signal when it reaches a preset threshold value.
Once:
When the trigger level is reached, the signal will be sampled and held onto the
display. This function is very interesting for detecting e.g. a short, once-only voltage
peak.
Run:
The scope automatically triggers if no triggering occurs for a fixed period of time.
Ideal for measuring DC voltages.
Hold the latest information in memory, releasing the hold button restarts the scope
sampling.It may be useful the freeze certain signals in order to study them or to
perform measurements using markers.
Calibrate the scope. Make sur all probes are disconnected prior to calibration!
