Thông tin sản phẩm

FEATURES

■	It has the digital equalizer circuit which is adjustable according to the characteristics of Pick-up.
■	The jitter quantity can be directly read by the meter and LCD indicator.
■	This unit converts a time difference between a data signal and the clock into a sigma value and indicated its jitter quantity as the percentage to the clock cycle on the meter indicator.
■	Changes in the jitter can be read continuously, due to T/V conversion method of measurement.
■	It can select either + or -edge of the data (EFM Plus) signal as the trigger edge, and also select +, - or +/- edge for jitter measurement.
■	The INHIBIT function is provided to inhibit jitter measurement of faulty section.
■	A GO/NO-GO result is indicted in relation to a preset jitter value.
■	The panel-lock function is provided to set measuring conditions.
■	A remote control function is provided.
