	Coordinate ruler		Logarithmic, linear
	Scan parameters		Frequency, AC voltage, AC current, DCV BIAS / DCI BIAS (100mA) / DCI BIAS (2A)
	Trigger mode	single	Manually trigger once, and complete a scan from the start point to the end point, and the next trigger signal starts a new scan

Comparators	Bin		10Bin, PASS, FAIL
	Bin deviation setting		Deviation value, percentage deviation value, off
	Bin mode		Tolerance, continuous
	Bin count		0-99999
	Discrimination		Up to four parameter limit ranges can be set for each file. The corresponding file number is displayed within the setting range of the four test parameter results. If the maximum file number range is exceeded, FAIL is displayed. The test parameters without the upper and lower limits are automatically ignored.
	PASS/FAIL indication		Meet Bin1-10, the PASS light on the front panel is on, otherwise the FAIL light is on
Data cache			201 measurement results can be read in batches
Store call	Inside		About 100M non-volatile memory test setting file
	External USB		Test setting file, screenshot graph, record file
