Carrier Freq
Sets the modulated carrier frequency.
Key access:
Mode > ASK/FSK Modulation Analysis
Symbol Rate
This specifies the fundamental symbol rate of the signal to
be analyzed. The values should be positive. The non- positive
value will be converted to 1Hz. The measurement accuracy
will be impacted if this value isn’t set precisely.
Key access:
Mode > ASK/FSK Modulation Analysis
Filter Setup
Accesses the Filter setup submenu for further configuration.
Key access:
Mode > ASK/FSK Modulation Analysis
