Usage of storage recorder: Multi channel waveform recorder&arbitrary waveform signal source, two in one

One storage recorder can achieve multi-channel arbitrary waveform generation function and waveform measurement recording function. By changing the amplitude and frequency of the signal and editing various waveforms, it is easy to observe waveforms while changing experimental conditions.

Usage of storage recorder: waveform observation of frequency converter - actual measurement section

The storage recorder MR8847A can achieve rich waveform observation with a sampling speed of 20MS/s and all channel insulated inputs (up to 16ch).

Multiple phenomena can be recorded simultaneously, such as voltage, current, torque, and rotation signals on the primary and secondary sides of the frequency converter, ranging from high voltage to small voltage.

The recorded waveform can be zoomed in and out to display the screen, and the Zoom function can be used to scroll and display the parts that need to be viewed in two separate screens.

Usage of storage recorder: waveform observation of frequency converter - connection section

All channels of the MR8847A storage recorder are insulated inputs, making it easy to connect multiple signals.

Both analog inputs and input channels are insulated from the host by insulating components.

The input of current can also improve the efficiency of connection work through a dedicated unit that can be directly connected to sensors.

Usage of storage recorder: waveform observation of frequency converter - settings section

The storage recorder MR8847A displays the settings in a list on the large screen. The input conditions for multiple channels can also be configured separately for each input channel. Introduce the settings through practical operation of the actual machine.

Usage of Storage Recorder: Differences from Oscilloscope

The storage recorder MR8847A can safely and efficiently observe and connect the waveform of the frequency converter compared to digital oscilloscopes through "insulated input" and "rich input units". The newly added 5 new units can support a wide range of measurement work.

20MS/s high-speed sampling&insulated input for all channels

The MR8847A storage recorder is capable of measuring all channels at a multi-channel, high-speed sampling rate of 20MS/s (resolution 50ns).

It can measure the rising edge of pulses with high precision or capture sudden abnormal transient waveforms.

Insulated terminals are used between the analog input channels and between the input channels and the host, so measurements can be taken with confidence.

1 instrument completes waveform generation and recording: arbitrary waveform generation unit U8793

One storage recorder can achieve arbitrary waveform generation and waveform recording measurement functions.

By changing the amplitude and frequency of the signal and editing various waveforms, it is easy to observe waveforms while changing experimental conditions.

Using Attachment SF8000 (waveform creation software), in addition to editing waveforms, it is also possible to perform simple and quick operations such as noise superposition and waveform multiplication.

High voltage input without differential probe: High voltage unit U8974

The maximum voltage is DC1000V, and AC700V can be directly input without the need for differential probes required for previous high-voltage measurements.

The maximum rated voltage to ground is 1000V (CAT III) and 600V (CAT IV).

There are a total of 13 diverse measurement units, which can be flexibly used in various measurement scenarios

Five new high-performance units have been added, expanding the measurement range of the storage recorder.

Inverter and UPS testing

Action testing and evaluation during load changes, confirmation of UPS switching actions

Power Monitor&Data Acquisition Instrument

Logical input, maximum 64ch

MR8847A comes standard with 16ch logic.

Up to 3 logic input units can be installed, with a maximum of 64ch for simultaneous recording.

It can display all channel waveforms in one screen, which is very suitable for timing testing.

And it can simultaneously record simulated waveforms for up to 10 hours.

Accurately record important data

Select data recording methods based on different purposes.

MEM function

Sample according to the set cycle and record all data in real-time.

REC function

Sample according to the set period, only recording the maximum and minimum values in each interval.

FFT analysis function

Capable of performing single signal FFT for spectrum analysis, dual signal FFT for transfer function analysis, and octave band analysis used in acoustic analysis.

X-Y recorder

Data can be saved in chronological order, replacing the previous requirement of backing up data records with paper sheets.

By controlling the UP/DOWN of the pen in X-Y recording, only the required data can be recorded.

Replace mechanical pen recorders.

Can perform waveform qualification assessment

Record and monitor whether the waveform is within the qualified area, or simply judge the signal waveform that is difficult to judge with the naked eye.
