WAVECOM Decoders v6.15 W40PC, W41PC, W51PC

Advanced Topics

•

The option

"Trigger Mode"

allows the Real-Time-Oscilloscope to trigger on a "Positive" or a

"Negative" slope. It is possible to switch it "Off".

The option

"Trigger Level"

allows to set conventional level driven triggering. The range lies

99% and –99%.

The vertical sensitivity may be set with the option

"Time/Div"

. Therefore nine predefined

values are available, which covers a range from 200

s up to 100 ms per division.

Using the

"Oscilloscope Gain"

option, the horizontal sensitivity may be adjusted from 0%

to 100%.

FSK ANALYSIS

The FSK Analysis mode is an important tool for the user to measure the radio transmission
properties of baudrate and frequency shift. The magnitude of these properties may help
identify the transmission being monitored.
