MDO-2000A series User Manual 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.
ADVANCED CONFIGURATION 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.
MDO-2000A series User Manual Progress Indicator Indicates the number of segments that have to been captured relative to the set number of segments. Run/Stop Indicator Stop: The segments have finished acquiring or have been stopped. Run: The scope is ready to acquire segments. Set the Number of Segments Note Panel Operation Before the Segment function can be used, set the trigger settings as appropriate for the signal you wish to use.

MDO-2000A series User Manual MAINTENANCE Three types of maintenance operations are available: Signal Path Compensation, Vertical Accuracy Calibration and Probe Compensation. Run these operations when using the MDO2000A in a new environment. How to use the SPC function............................................................. 315 Vertical Accuracy Calibration ............................................................. 315 Probe Compensation ..............................................................
MAINTENANCE How to use the SPC function Background Signal Path Compensation (SPC) is used to compensate the internal signal path due to ambient temperature. SPC is able to optimize the accuracy of the oscilloscope with respect to the ambient temperature. Panel Operation 1. Press the Utility key. Utility 2. Press System from the bottom menu. 3. Press SPC from the side menu. A message showing a brief introduction to SPC appears on the screen.
MDO-2000A series User Manual 2. Press System from the bottom menu. 3. Press more 1 of 3 from the side menu. 4. Press Self Cal on the side menu. 5. Press Vertical on the side menu. 6. A message appears to “Now performing vertical calibration… CH1 Connect the CAL output to channel, then press the Vertical key”. 7. Connect the calibration signal from the rear panel to the Channel 1 input with a BNC cable.
MAINTENANCE 8. Press Vertical again after connecting CAL to the channel 1 input. The calibration for Channel 1 starts and ends automatically, in less than 5 minutes. A message is displayed when the calibration procedure has ended. 9. Repeat the above step for Channel 2 when prompted. 10. When the calibration for all channels has completed, the display goes back to the default state. Probe Compensation Panel Operation 1.

Press the Autoset key. The compensation signal appears on the display. 7. Press the Display key, then set the display type to Vector.
MAINTENANCE 8. Turn the adjustment point on the probe to make the waveform as square as possible.
MDO-2000A series 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 37 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 133 for Single trigger details. The probe waveform is distorted. You might need to compensate the probe. For details, see page 317. Autoset does not catch the signal well. The Autoset function cannot catch signals under 10mV or 20Hz. Please use the manual operation.

APPENDIX Updating the Firmware Background New firmware can be downloaded from the our website in the MDO products section. Place a copy of the firmware file (xxx.upg) onto the root directory of a USB flash disk. Panel Operation 1. Put the USB drive that contains Front panel the firmware into the front panel USB port. 2. Power up the oscilloscope and at the same time, rotating the “VARIABLE” knob several times until the oscilloscope boot in the firmware upgrade mode as in the snapshot below.
MDO-2000A series User Manual 4. Press the “Start Now” (F1) key. The oscilloscope will automatically start upgrading the firmware. Or press the “Cancel” (F3) key to quit the firmware upgrading procedure. 5. When the status indicator shows the complete status (status indicator in yellow completely) and a message of “Update NAND flash success” will appear on the top of status indicator. The firmware upgrading procedure is completed. 6. Restart the oscilloscope manually.
