ADVANCED CONFIGURATION Segmented Memory Acquisition The advanced segmented memory utility allows the scope memory to be divided into different segments. Each time the scope is triggered, it only acquires data for one segment of memory at a time. This allows you to optimize the scope memory to only perform signal acquisition during important signal events.
MSO-2000E & 2000EA User Manual Segmented memory acquisition example: Segment n Segment n+1 Segment n+2 Segment n+3 Segment n+4 Segment n+5 As shown above, the memory is divided into segments to increase the number of events that can be effectively captured with the same acquisition memory. Also notice that the scope doesn’t need to rearm the trigger between each segment, this makes the segmented memory function especially useful for high speed signals.

MSO-2000E & 2000EA User Manual FAQ • I connected the signal but it does not appear on the display. • I want to remove the (Measurement result / FFT result / Help contents) from the display. • The waveform does not update (frozen). • The probe waveform is distorted. • Autoset does not catch the signal well. • The display image printout is too dark on the background. • The date and time settings are not correct. • The accuracy does not match the specification.
FAQ The waveform does not update (frozen). Press the Run/Stop key to unfreeze the waveform. See page 46 for details. If this does not help, the trigger mode might be set to Single. Press the Single key to exit Single mode. See page 154 for Single trigger details. The probe waveform is distorted. You might need to compensate the probe. For details, see page 333. Autoset does not catch the signal well. The Autoset function cannot catch signals under 10mV or 20Hz. Please use the manual operation.
MSO-2000E & 2000EA User Manual The accuracy does not match the specification. Make sure the device is powered On for at least 30 minutes, within +20°C~+30°C. This is necessary to stabilize the unit to match the specification. For more information, contact your local dealer or GW Instek at www.gwinstek.com / marketing@goodwill.com.tw.
