BINNINGOPERATIONThe SR715/720 has built in features to aid in component sorting. This is especially useful for productiontesting, incoming inspection, device matching or tests where multiple devices of similar value must bemeasured. The binning feature simplifies parts sorting by eliminating the need to read the major and minorparameters and then deciding what to do with the part. [Store] and [Recall] allow up to 9 binning configurationsto be entered and saved making it easy to change between different setups. Binning configurations can alsobe entered over one of the computer interfaces. The SR715/720 can sort components into as many as tenseparate bins - eight pass bins, a minor parameter failure bin, and a general failure bin. Binning operationscan either be performed from the front panel, in the BINS display, the standard RS232 computer interface orthe optional GPIB or Handler interface.There are three different types of binning schemes that the SR715/720 supports: Pass/Fail, Overlapping, andSequential. Pass/Fail has only two bins; good parts and everything else. Overlapping or nested bins have onenominal value and are sorted in progressively larger bins (+/-1%, +/-2%, +/-3%). Sequential bins can havedifferent nominal values, each separated by a percentage (.9*nom, .95*nom, 1.0*nom, 1.05*nom, with 5%limits) or a single nominal value and asymmetrical limits (-3% to -1%, -1% to 1%, 1% to 3%). Limits are pairsand can be symmetrical (+/-2%) or asymmetrical (-5% to -1%). Examples of different binning schemes arelisted below.Nested Bins 100 Ω resistors sorted into progressivelylooser symmetric limits pairs with a single nominal value.Nominal value = 100 ΩBin0: +/-1%Bin1: +/-2%Bin2: +/-3%Bin3: +/-4%Bin8: QDR failure bin (if Q was too high)Bin9: General Failure bin (parts that don't fall intoany other bin)1.
