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:
Number of channels to be used
Maximum sampling rate that can be set
SSD HDD

Only if the following Hioki-designated options are used, the real-time save operation with the instrument is
guaranteed:
• Model U8332 SSD Unit
• Model U8333 HD Unit
• Model Z4006 USB Drive
• Model Z4001 and Model Z4003 SD Memory Card

If the instrument plots non-existent waveforms (aliasing)
If a measured signal oscillates at a higher frequency compared to the specied 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.
Actual input signal
Sampling interval
: Sampled points
Observed waveform
A sampling interval longer than the cycle
of the input signal causes aliasing.
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.

Conguring 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.

Set [Measurement method] to [Envelope].
NormalDoes not use the envelope.
Envelope Uses the envelope.
• Normal:
The instrument records data at the specied sampling rate.
• Envelope:
At the specied recording interval, the instrument records the maximum and minimum values among data
sampled within each specied 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.

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.

Set [Display].
OnDisplays the waveforms on the waveform screen.
Color Allows you to select display colors of the waveforms. You can also select the
same color as the lines acquired through other channels.
Invert
(Off, On)
When the signs of displayed waveforms are reversed, the waveforms can be
inverted.
Refer to “3.4 Inverting the Waveform (Invert Function)” (p. 49).
Vernier Allows you to ne-adjust the input voltage freely on the waveform screen
(display adjustment only). When recording physical values such as noise,
temperature, and acceleration with sensors, you can adjust those amplitudes,
facilitating calibration.
Refer to “3.3 Fine-Adjusting Input Values (Vernier Function)” (p. 48).
Off Displays no waveforms.
7
Set [Scaling].
Refer to “3.2 Converting Input Values (Scaling Function)” (p. 42).
8
Switch the channels.
Tap the corresponding location to switch the channels.
9
Set [Digital lter] for each channel. (Model MR6000-01 only)
The [Df] setting is displayed for only channels with [Digital lter] set to [On], allowing you to set the digital
lter for each channel.
