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

get_mgap() → float[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:MGAP
value: float = driver.trigger.spectrum.get_mgap()

Sets a minimum time during which the IF signal must be below the trigger threshold before the trigger is armed so that an IF power trigger event can be generated.

return:

minimum_gap: numeric Range: 0 s to 0.01 s, Unit: s

get_offset() → float[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:OFFSet
value: float = driver.trigger.spectrum.get_offset()

Defines the trigger offset, i.e. the offset of a triggered zero span measurement relative to the corresponding trigger event.

return:

trigger_offset: numeric Range: -0.5 s to 0.5 s, Unit: s

get_slope() → SignalSlopeExt[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:SLOPe
value: enums.SignalSlopeExt = driver.trigger.spectrum.get_slope()

Qualifies whether the trigger event is generated at the rising or at the falling edge of the trigger pulse (valid for external and power trigger sources) .

return:

slope: REDGe | FEDGe REDGe: rising edge FEDGe: falling edge

get_source() → str[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:SOURce
value: str = driver.trigger.spectrum.get_source()

Selects the source of the trigger events. Some values are always available. They are listed below. Depending on the installed options, additional values are available. You can query a list of all supported values via TRIGger:… :CATalog:SOURce?.

return:

source: string ‘Free Run’: free run (untriggered) ‘Video’: power trigger at video band

get_threshold() → float[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:THReshold
value: float = driver.trigger.spectrum.get_threshold()

Defines the trigger threshold for power trigger sources.

return:

threshold: numeric Range: -50 dB to 0 dB, Unit: dB (full scale, i.e. relative to reference level minus external attenuation)

get_timeout() → float[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:TOUT
value: float or bool = driver.trigger.spectrum.get_timeout()

Selects the maximum time that the measurement waits for a trigger event before it stops in remote control mode or indicates a trigger timeout in manual operation mode. This setting has no influence on ‘Free Run’ measurements.

return:

trigger_timeout: (float or boolean) numeric | ON | OFF Range: 0.01 s to 300 s, Unit: s ON | OFF enables or disables the timeout check.

set_mgap(minimum_gap: float) → None[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:MGAP
driver.trigger.spectrum.set_mgap(minimum_gap = 1.0)

Sets a minimum time during which the IF signal must be below the trigger threshold before the trigger is armed so that an IF power trigger event can be generated.

param minimum_gap:

numeric Range: 0 s to 0.01 s, Unit: s

set_offset(trigger_offset: float) → None[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:OFFSet
driver.trigger.spectrum.set_offset(trigger_offset = 1.0)

Defines the trigger offset, i.e. the offset of a triggered zero span measurement relative to the corresponding trigger event.

param trigger_offset:

numeric Range: -0.5 s to 0.5 s, Unit: s

set_slope(slope: SignalSlopeExt) → None[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:SLOPe
driver.trigger.spectrum.set_slope(slope = enums.SignalSlopeExt.FALLing)

Qualifies whether the trigger event is generated at the rising or at the falling edge of the trigger pulse (valid for external and power trigger sources) .

param slope:

REDGe | FEDGe REDGe: rising edge FEDGe: falling edge

set_source(source: str) → None[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:SOURce
driver.trigger.spectrum.set_source(source = 'abc')

Selects the source of the trigger events. Some values are always available. They are listed below. Depending on the installed options, additional values are available. You can query a list of all supported values via TRIGger:… :CATalog:SOURce?.

param source:

string ‘Free Run’: free run (untriggered) ‘Video’: power trigger at video band

set_threshold(threshold: float) → None[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:THReshold
driver.trigger.spectrum.set_threshold(threshold = 1.0)

Defines the trigger threshold for power trigger sources.

param threshold:

numeric Range: -50 dB to 0 dB, Unit: dB (full scale, i.e. relative to reference level minus external attenuation)

set_timeout(trigger_timeout: float) → None[source]

# SCPI: TRIGger:GPRF:MEASurement<Instance>:SPECtrum:TOUT
driver.trigger.spectrum.set_timeout(trigger_timeout = 1.0)

Selects the maximum time that the measurement waits for a trigger event before it stops in remote control mode or indicates a trigger timeout in manual operation mode. This setting has no influence on ‘Free Run’ measurements.

param trigger_timeout:

(float or boolean) numeric | ON | OFF Range: 0.01 s to 300 s, Unit: s ON | OFF enables or disables the timeout check.
