class BufferCls

Buffer commands group definition. 7 total commands, 1 Subgroups, 6 group commands

clear(buffer: str) → None

# SCPI: CLEar:BASE:BUFFer
driver.buffer.clear(buffer = 'abc')

Clears the contents of a buffer. You get an empty buffer that you can fill with new commands.

param buffer:

string

continue_py(buffer: str) → None

# SCPI: CONTinue:BASE:BUFFer
driver.buffer.continue_py(buffer = 'abc')

Reactivates a buffer which was deactivated via method RsCmwBase.Buffer.stop) . The R&S CMW continues writing data to the buffer.

param buffer:

string

delete(buffer: str) → None

# SCPI: DELete:BASE:BUFFer
driver.buffer.delete(buffer = 'abc')

Deletes a buffer.

param buffer:

string

fetch(buffer: str, line_number: int) → str

# SCPI: FETCh:BASE:BUFFer
value: str = driver.buffer.fetch(buffer = 'abc', line_number = 1)

Reads the contents of a buffer line. Buffer contents are stored line by line. Every query generates a new buffer line. The queries are not stored together with the results. Reading buffer contents is non-destructive. The lines can be read in arbitrary order.

param buffer:

No help available

param line_number:

integer Line number, selects the line to be read.

return:

line: No help available

start(buffer: str) → None

# SCPI: STARt:BASE:BUFFer
driver.buffer.start(buffer = 'abc')

Creates and activates a buffer. If the buffer exists already, it is cleared (equivalent to method RsCmwBase.Buffer.clear) .

param buffer:

string The buffer is identified via this label in all buffer commands.

stop() → None

# SCPI: STOP:BASE:BUFFer
driver.buffer.stop()

Deactivates the active buffer. Only one buffer can be active at a time. The buffer and its contents are maintained, but data recording is paused. Use method RsCmwBase.Buffer.continue_py to reactivate a buffer.

stop_with_opc(opc_timeout_ms: int = -1) → None

# SCPI: STOP:BASE:BUFFer
driver.buffer.stop_with_opc()

Deactivates the active buffer. Only one buffer can be active at a time. The buffer and its contents are maintained, but data recording is paused. Use method RsCmwBase.Buffer.continue_py to reactivate a buffer.

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

param opc_timeout_ms:

Maximum time to wait in milliseconds, valid only for this call.

Cloning the Group

# Create a clone of the original group, that exists independently
group2 = driver.buffer.clone()
