get_port() → int[source]

# SCPI: [SOURce<HW>]:BB:DRM:PORT
value: int = driver.source.bb.drm.get_port()

Sets the port. Enter the port number on that the UDP/ receiver listens for UDP datagrams.

return:

drm_port: integer Range: 0 to 65535

get_source() → DrmInputSignalSource[source]

# SCPI: [SOURce<HW>]:BB:DRM:SOURce
value: enums.DrmInputSignalSource = driver.source.bb.drm.get_source()

Sets the modulation source for the input signal.

return:

drm_source: EXTernal| FILE EXTernal Uses a / stream input at the ‘LAN’ connector of the host PC of the R&S SMCV100B. FILE Reads the input stream from a *.dcp file. The binary file contains the MDI data encapsulated in packets.

get_state() → bool[source]

# SCPI: [SOURce<HW>]:BB:DRM:STATe
value: bool = driver.source.bb.drm.get_state()

Activates the standard and deactivates all the other digital standards and digital modulation modes in the same path.

return:

state: 1| ON| 0| OFF

get_type_py() → DrmInputSignalLayerType[source]

# SCPI: [SOURce<HW>]:BB:DRM:TYPE

preset() → None[source]

# SCPI: [SOURce<HW>]:BB:DRM:PRESet
driver.source.bb.drm.preset()

Sets the parameters of the digital standard to their default values (*RST values specified for the commands) . Not affected is the state set with the command SOURce<hw>:BB:DRM:STATe.

preset_with_opc(opc_timeout_ms: int = -1) → None[source]

# SCPI: [SOURce<HW>]:BB:DRM:PRESet
driver.source.bb.drm.preset_with_opc()

Sets the parameters of the digital standard to their default values (*RST values specified for the commands) . Not affected is the state set with the command SOURce<hw>:BB:DRM:STATe.

Same as preset, but waits for the operation to complete before continuing further. Use the RsSmcv.utilities.opc_timeout_set() to set the timeout value.

param opc_timeout_ms:
