When the real-time waveform calculation (Model MR6000-01 only) is set to [On], a sampling rate of 200 MS/s
cannot be selected.
When the real-time save is set to [On], due to the combination of the number of channels to be used and save
destinations, the maximum sampling rate that can be set varies as follows:
Maximum sampling rate that can be set
Number of channels to be used
1 channel to 2 channels 20 MS/s 10 MS/s 5 MS/s

Sampling rate
If the instrument plots non-existent waveforms (aliasing)
If a measured signal oscillates at a higher frequency compared to the specied sampling rate, the
instrument may plot non-existent waveforms oscillating at a lower frequency than that of the actual
signal when the signal frequency reaches a certain level. This phenomenon is called aliasing.
1
Measurement Method
Actual input signal
A sampling interval longer than the cycle
of the input signal causes aliasing.
Sampling interval
To plot a sign wave that allows you to observe the peaks of the sine wave on the LCD without any
aliasing, the instrument needs to sample the waveform at a minimum of 25 points per cycle.

To set the sampling rate automatically
Refer to “3.7 Measurement With the Auto-range setting” in Quick Start Manual.

Conguring Measurement Conditions
Update rate of each module
The data update rate is not allowed to exceed the maximum sampling rate of each module.
The same data are measured until they get updated, causing the instrument to plot a stair-step
waveform.
In addition, even though the same signal is measured simultaneously, values may vary due to
differences in the sampling rate, frequency range, and frequency characteristics of modules.

Envelope Uses the envelope.
• Normal:
• Envelope:
• Values to be acquired using the envelope
A set of sampled data acquired using the envelope consists of two values: the maximum value and the
minimum value. These values are taken from the measured values acquired at an over-sampling rate during
the recording interval set in [Sampling]. When shown on the screen, they are displayed as if they range in
amplitude. When saved in an external storage device, the data of the maximum and minimum values are
stored for a single instance of measurement.
The instrument records data at the specied sampling rate.
At the specied recording interval, the instrument records the maximum and minimum values among data
sampled within each specied recording interval at an over-sampling rate* of 100 MS/s. Hence, even though
a relatively longer recording interval is set, peaks of uctuations can be recorded without being missed.

Starting/Stopping the Measurement
1.5 Starting/Stopping the Measurement
Starting a measurement
Pressing the START key starts a measurement.
• Waveform data displayed on the screen is cleared once the measurement starts.
• You can also start the measurement by inputting signal into the external control terminal.
Refer to “10 Controlling the Instrument Externally” (p. 179).
Waveform display during measurement
In general, the waveforms are displayed after the specied recording length of data has been
acquired. When the measurement is performed at a relatively slow speed, the waveforms are
displayed while the data is being acquired.
However, even if a slow-speed range is set, the waveforms are displayed after the data of the
whole waveform has been acquired, depending on the overlay or magnication setting.
To save data automatically during measurement
Refer to “Saving waveform data automatically” (p. 68).
Stopping the measurement
Pressing the STOP key once stops the measurement after the waveforms of the specied recording
length have been acquired.
Pressing the STOP key twice stops the measurement immediately.

Reading Measured Values (Trace Cursors)
Using trace cursors on the waveform screen allows you to read measured values (scaled
value when the scaling is used). Up to eight trace cursors can be displayed simultaneously.
You can read differences in times and measured values at any two selected among them.
The time lag, for example, shows the difference in time between Trace cursor A and Trace
cursor B when they are enabled.
Tap [Trace cursor].

When the multiple trace cursors are displayed, the cursor values acquired at the two trace cursors are
displayed on the waveform screen (Cursor values 1 and 2).
Every time you tap [1: Trace cursor] (or [2: Trace cursor]), the values of Cursor values 1 (or Cursor values 2)

Changing the magnication of the waveform display while moving the trace
cursor
Sliding your nger upward on the screen while dragging the trace cursor enlarges the waveform
display centered around the trace cursor in proportion to the dragging distance. Sliding your nger
downward compresses the waveform display.
Once you have adjusted the display to a suitable size, move the trace cursor along the horizontal
axis to change the display position.
Releasing your nger from the screen reverts the display to the original magnication.
To move the trace cursor using the rotary knob X
When [Cursor] is assigned to the rotary knob, you can move the active trace cursor with the rotary
knob X.
If the trace cursor is not displayed on the screen even though it is enabled
Check the position of the trace cursor on the scroll bar. (p. 31)
