Functional description Functional description III - TRIGGER system (cont'd) HOLD-OFF Use Hold-Off to obtain a stable display with complex signals, such as pulse trains, for example. The Hold-Off time is the time interval between the detection of a valid triggering event and the time when the oscilloscope is ready to detect another triggering event. The oscilloscope will not trigger during the Hold-Off time; the triggering circuit is disabled during this time.
Functional description Functional description IV - ACQUISITION system Acquisition menu During the acquisition of a signal, the oscilloscope converts it to digital format and displays a trace. The acquisition mode determines how the signal is digitized. The time base range determines the duration of recording and the elementary acquisition pitch. Press the "ACQUIRE" key.
Functional description Functional description IV - ACQUISITION system (cont'd) Sample The oscilloscope samples the signal at regular intervals to construct the trace. In general, this mode gives an accurate representation of the signal. Advantage Disadvantages Peak detection Advantage Drawback 44 You can use this mode to reduce random noise. The "sample" mode does not capture the rapid variations of the signal (glitches) that may occur between two successive samples.
Functional description Functional description IV - ACQUISITION system (cont'd) Averaging Advantage The oscilloscope performs several acquisitions, determines the mean, and displays the resulting trace. You can use this mode to reduce random noise. Mode Equivalent time sampling ETS Real time sampling RTS The equivalent time sampling (ETS) mode can reach a horizontal resolution of 20ps (equivalent to 50GSa/s). This mode is suited to the observation of repetitive signals.
Functional description Functional description IV - ACQUISITION system (cont'd) Time base The oscilloscope digitizes the traces through the acquisition of an input signal at precise points. The time base is used to control the trace sampling rate. Use the "S/div" knob to adjust the time base coefficient scale that suits you. Undersampling Aliasing occurs when the sampling rate of the oscilloscope is not fast enough to reconstruct a trace precisely.
Functional description Functional description IV - ACQUISITION system (cont'd) "X" corresponds to "linear" interpolation: Configure the Sampling mode Press the "Mode" key and choose "Real Time" (Real Time Sampling, RTS) or "Equivalent Time" (Equivalent Time Sampling, ETS).

Functional description Functional description V - DISPLAY system (cont'd) X-Y format The XY format is used to analyse phase differences between signals using Lissajous figures. The XY format plots the voltage in channel CH1 (horizontal X axis) against the voltage in channel CH2 (vertical Y axis). The oscilloscope uses the triggerless acquisition mode and displays the data in the form of dots. The "XY" mode accepts sampling rates ranging from 25KSa/s to 250MSa/s (1-2.5-5 staging).
Functional description Functional description VI - MEASUREMENT system The oscilloscope displays waveforms, in other words variations of the signal amplitude (voltage) as a function of time. The oscilloscope also displays the vertical and horizontal ranges and the results of cursor and automatic measurements. Scale measurement This method allows a rapid visual estimate.

Before starting the "Auto-Calibration", you must disconnect the probes and leads from the input BNCs. Then press the "Utility" key and choose "Auto Cal.

The rectangles represent the keys on the front panel. The seven rectangles flanked by arrows represent the knobs on the front panel. The square below these seven rectangles represents the switches built into these knobs. Test all of the knobs and their switches. Also check that the backlit keys operate correctly.
Functional description Functional description VIII - UTILITY 3/4 Update of the Embedded Software Steps Update of the "Firmware" from a USB key. The embedded software of the oscilloscope can be updated directly from a USB key. This takes about two minutes. 1. Connect the USB key containing the new "Firmware" version to the host USB port on the front panel of the oscilloscope. 2. Press the UTILITY key to access the "Utility" Menu. 3. Press the "Next Page" key to access the third page of the "Utility" menu.

Functional description Functional description VIII - UTILITY 4/4 Record mode The Record mode is used to record up to 2500 frames of 2.5 kpoints with time base ranges from 50ms/div to 2.5ns/div. The Record mode is the complement of the Recorder mode, which for its part is suited to slow signals and operates with time base ranges from of 100ms/div to 50s/div. The Record mode is used to record the signals of channel CH1 or CH2 with a maximum record length of 2500 points.
Functional description Functional description VIII - UTILITY system 4/4 (cont'd) Recorder Signal recorder menu The Recorder mode is the complement of the Record mode, suited to slow signals, with time base ranges from 100ms/div to 50s/div Recorder allows the continuous recording of signals in real time. The oscilloscope can therefore record the signals and read them back to display them again on the screen (Replay).

Functional description Remote control Remote control There are two remote control methods: User-programmable The user can control the oscilloscope using Standard Commands for Programmable Instruments (SCPI). See the Programming Guide for more information about the commands and the programming. The user can control the oscilloscope remotely using EasyScopeX or SXDOX PC software. National Instruments Corporation's "Measurement & Automation Explorer" software can also be used to control the oscilloscope.

Messages Messages / Help (cont'd) Diagnostics Steps 1. After power up ("ON"), the screen of the oscilloscope displays nothing: - Check the connection of the power cord. - Make sure that the device is in fact on. - Then restart the oscilloscope. - If the oscilloscope still fails to operates, contact METRIX CHAUVIN-ARNOUX division. 2. The oscilloscope displays no trace after a signal is injected on the inputs: (1) Check the lead of the probe. (2) Check the connecting cable.
