1. Valid pixels are 99.99% and more. Below 0.01% of fixed points of black, blue, green or red are not regarded as failure.
Marker function
Marker type and number
10 independent markers per trace. Reference marker available for delta marker operation.
Marker search
Search type
Maximum value, minimum value, multi-peak, multi-target, peak, peak left, peak right, target, target left, target
right, and width parameters with user defined bandwidth values.
Search track
Search range
Marker X-axis display
Others
Performs search by each sweep
User define
Sweep parameter value, sweep elapsed time, or relaxation time (1/( 2πf))
Marker continuous mode, ∆ marker mode, marker coupled mode,
Marker value substitution (Marker→), marker zooming, marker table, marker statistics
Equivalent circuit analysis
Circuit model
3-component model (4 models), 4-component model (3 models)
Analysis type
Equivalent circuit parameters calculation, frequency characteristics simulation
Limit Line Test
Funcions
Define the test limit lines that appear on the display for pass/fail testing. Defined limits may be any combina-
tion of horizontal/sloping lines and discrete data points.
Other functions
