I/Os
I/Os are data processing objects that accept data (Input), process this data in a specific way, like e.g. adding, multiplying, filtering, etc. and then generate the processed data (Output). The inputs and outputs of the I/O block can either be time domain or frequency domain data.
The I/Os are categorized in the following categories:
Contents
Math I/Os
The Math I/Os perform a basic mathematical operation on one or more signals:
Gain / Offset
The Gain / Offset I/O multiplies a signal with a constant gain factor and adds a constant offset.
Add / Subtract
The Add / Subtract I/O adds or subtracts data of two or more sources.
Multiply / Divide
The Multiply / Divide I/O multiplies or divides data of two ore more sources.
Sqrt
The SQRT I/O calculates the square root of each sample of the source's data.
ABS
The ABS I/O takes the absolute value of each sample of the source's data.
Differentiate
The Differentiate I/O differentiates the source's data.
Integrate
The Integrate I/O integrates its source's data.
Logarithm
The Logarithm I/O calculates the logarithm of the source's data.Filter I/Os
The Filter I/Os perform a filtering operation on a signal or consecutive signals:
Filter
The Filter I/O filters the source's data using a user definable software filter.
Ideal filter
The Ideal filter I/O filters the source's data using an ideal user definable software filter.
Signal cleaner
The Signal cleaner I/O cleans up a periodical signal by removing noise and other unwanted distortions from the source's data.
Average
The Average I/O averages successive measurements and outputs the average of these measurements.Adjusting I/Os
The Adjusting I/Os perform an adjusting operation on a signal or consecutive signals:
Deskew
The Deskew I/O shifts the source's data in time.
Slice
The Slice I/O crops an input signal to a selectable slice of its input signal.
Limiter
The Limiter I/O limits or clips a signal to a certain range.
Comparator
The Comparator I/O compares a signal with a certain reference level.
Resampler
The Resampler I/O resamples the source's data to decrease or increase the sample frequency (and record length with the same ratio) of a signal.
Window
The Window I/O applies a window function to its input signal.Miscellaneous I/Os
The Miscellaneous I/Os perform an other operation on a signal or consecutive signals:
Min / Max detector
The Min / Max detector I/O detects minimum or maximum values of the source's data.
Data collector
The Data collector I/O appends the consecutive chunks of streaming data to each other to form a large record of consecutive data.
Reference
The Reference I/O remembers its input data until it is asked to copy the current input data. Use it to compare measurements.Analyzing I/Os
The Analyzing I/Os analyze the input data and extract specific information from it.
Duty cycle
The Duty cycle I/O determines the duty cycle of a signal.
RMS
The RMS I/O determines the True Root Mean Square value of a signal.
Maximum
The Maximum I/O determines the maximum value of a signal.
Maximum - Minimum
The Maximum - Minimum I/O determines the maximum-minimum or peak to peak value of a signal.
Minimum
The Minimum I/O determines the minimum value of a signal.
Phase difference
The Phase difference I/O determines the phase difference between its two input signals.
FFT
The FFT I/O is used for spectral analysis of a signal using a Fast Fourier Transformation
Power Spectral Density
Power Spectral Density is a distribution that tells about the average power distribution over a range of frequency components.
Histogram
The Histogram I/O creates a histogram of the input signal.
EMI
The EMI I/O creates an environment that can be used for EMI pre-compliance testing.Automotive I/Os
The Automotive I/Os perform automotive specific operations on the data.
Crankshaft angle
The Crankshaft Angle I/O converts a crankshaft position sensor signal into a crankshaft angle signal.
RPM
The RPM I/O converts a crankshaft signal into revolutions per minute.
EV charger control pilot analyzer
The EV Charger Control Pilot Analyzer I/O decodes the Control Pilot signal and shows the maximum available charge current and the charge status.Decoder I/Os
The Decoder I/Os decode serial communication data from the input data and present the decoded messages.
Pulse decoder
The Pulse decoder I/O decodes the two signals from a quadrature encoder to a pulse count/position.
I2C decoder
The I2C decoder I/O decodes analog data on the SDA and SCL lines of an I2C bus to I2C data.
UART / Serial decoder
The UART / Serial decoder I/O decodes analog data on a UART, RS232, RS485, MIDI, DMX, LIN or other compatible serial bus to serial data.
CAN decoder
The CAN decoder I/O decodes analog data to CAN data.
J1939 decoder
The J1939 decoder I/O extracts SAE J1939 SPN values from CAN messages.
SPI decoder
The SPI decoder I/O decodes analog data on an SPI bus to SPI data.
Base section to index
The Base section to index I/O "fills gaps" in data with the last known value.Obsolete I/Os
Obsolete I/Os are I/Os that are replaced by new I/Os. They are still present in the software for existing saved setups but can no longer be used for new measurements.
