The MEASUrement:SOUrce1:SIGType command.

Description
  • This command sets or queries the type of input signal used for measurement SOURCE, 1 or 2. To ensure accurate measurements, use this command to specify the input-signal type for the measurement source.
Usage
  • Using the .query() method will send the MEASUrement:SOUrce1:SIGType? query.
  • Using the .verify(value) method will send the MEASUrement:SOUrce1:SIGType? query and raise an AssertionError if the returned value does not match value.
  • Using the .write(value) method will send the MEASUrement:SOUrce1:SIGType value command.
SCPI Syntax
- MEASUrement:SOUrce1:SIGType {PULse|EYE}
- MEASUrement:SOUrce1:SIGType?
Info
  • PULSE is for generic signals that are not associated with synchronous communications standards.
  • EYE is for synchronous-communication signals with NRZ-like characteristics (nonreturn to zero).

MeasurementStatistics

Bases: SCPICmdRead

The MEASUrement:STATIstics command tree.

Usage
  • Using the .query() method will send the MEASUrement:STATIstics? query.
  • Using the .verify(value) method will send the MEASUrement:STATIstics? query and raise an AssertionError if the returned value does not match value.
Properties

Usage
  • Using the .write(value) method will send the MEASUrement:STATIstics:COUNt value command.
SCPI Syntax
- MEASUrement:STATIstics:COUNt {RESET}
Info
  • RESET clears existing measurement statistics from memory.

mode property

Return the MEASUrement:STATIstics:MODe command.

Description
  • This command controls the operation and display of measurement statistics. This command is equivalent to selecting Measurement Setup from the Measure menu, clicking the Statistics button and then choosing the desired Measurement Format.
Usage
  • Using the .query() method will send the MEASUrement:STATIstics:MODe? query.
  • Using the .verify(value) method will send the MEASUrement:STATIstics:MODe? query and raise an AssertionError if the returned value does not match value.
  • Using the .write(value) method will send the MEASUrement:STATIstics:MODe value command.
SCPI Syntax
- MEASUrement:STATIstics:MODe {OFF|ALL|VALUEMean|MINMax|MEANSTDdev}
- MEASUrement:STATIstics:MODe?
Info
  • OFF turns off all measurements. This is the default value.
  • ALL turns on statistics and displays all statistics for each measurement.
  • VALUEMean turns on statistics and displays the value and the mean (µ) of each measurement.
  • MINMax turns on statistics and displays the min and max of each measurement.
  • MEANSTDdev turns on statistics and displays the mean and standard deviation of each measurement.

weighting property

Return the MEASUrement:STATIstics:WEIghting command.

Description
  • This command specifies the time constant for mean and standard deviation statistical accumulations.
Usage
  • Using the .query() method will send the MEASUrement:STATIstics:WEIghting? query.
  • Using the .verify(value) method will send the MEASUrement:STATIstics:WEIghting? query and raise an AssertionError if the returned value does not match value.
  • Using the .write(value) method will send the MEASUrement:STATIstics:WEIghting value command.
SCPI Syntax
- MEASUrement:STATIstics:WEIghting <NR1>
- MEASUrement:STATIstics:WEIghting?
Info
  • <NR1> is the number of samples used for the mean and standard deviation statistical accumulations.

MeasurementStatisticsCount

Bases: SCPICmdWrite
