TestProcess.Source.Time.Marker

The process of sourcing a time marker signal from a device.

This process is typically used to calibrate the sweep time accuracy on devices such as spectrum analyzers or oscilloscopes.  (more…)

TestProcess.Source.Voltage.DC.Delta.Voltage

The process of sourcing 2 DC (Direct Current) voltage signals.  First the VoltsRef signal is sourced and measured on the UUT, that value is stored as reference.  Then the test Volts signal is sourced and measured on the UUT and stored as reading.  The test result is returned as (reading – reference).

These two voltage signals are often used when calibrating the DC gain of a device such as an Oscilloscope.   (more…)

TestProcess.Source.Ratio.Voltage.AC.Sinewave.Delta.Frequency

A test process the sources 2 sinusoidal AC Voltage signals at different frequencies keeping the voltage levels constant between the two frequencies. The FrequencyRef signal is sourced and the voltage is measured by the UUT and saved as the Reference value.  Then the signal is changed to the test Frequency signal and the Test value is measured on the UUT.  The two measured values are compared, the results can be expressed as Delta Volts, dB or percent of change.

These two sinusoidal signals are often used when calibrating bandwidth or frequency response on an Oscilloscope or similar device. (more…)
