class OsnmaCls

Osnma commands group definition. 20 total commands, 4 Subgroups, 11 group commands

get_ad_delay() → int

# SCPI: [SOURce<HW>]:BB:GNSS:GALileo:OSNMa:ADDelay
value: int = driver.source.bb.gnss.galileo.osnma.get_ad_delay()

Sets an additional delay in subframes of the navigation data for the tag verification. The delay can depend on receiver implementation. You can set a delay of one subframe. A zero subframe delay corresponds to no delay.

return:

delay: integer Range: 0 to 1

# SCPI: [SOURce<HW>]:BB:GNSS:GALileo:OSNMa:ADKD
value: bool = driver.source.bb.gnss.galileo.osnma.get_adkd()

state: 1| ON| 0| OFF
