User Manual

Preface
Congratulations on choosing the Mictrack MT950 Low Power Analyzer. This manual shows how to easily use the unit. Make sure to read this manual carefully before using this product, so as to avoid delays or confusion with its operation. Please note that specifications and instructions are subject to change without notice to facilitate product improvement.
Updates and changes will be integrated into the latest release. The manufacturer assumes no responsibility for any errors or omissions in outdated documents.

Overview

With the development of NB-IoT & CAT M1 technology, the Mictrack R&D team has launched a variety of positioning devices with long battery life and ultra-low power consumption. In the process of developing ultra-low-power devices, the Mictrack R&D team felt that it was difficult to accurately measure power consumption data with ordinary instruments, and high-end instruments were too expensive. The MT950 can be used for power consumption testing and evaluation of NB-IoT, Cat M1, Bluetooth, Zigbee,  LoRa, etc. It is very cost-effective and suitable for R&D, testing, production of small and medium-sized enterprises, and learning of students and electronic enthusiasts.

Specifications

MT950 Interface

In the box

• Power Analyzer MT950
• USB Cable (0.5m)
• Test Wire Cable (0.5m)
• DC Power Cable (0.5m)

Quick Start

• Install and run the power analyzer PC software.
• Use the USB cable to connect the analyzer and the computer, the PC software will show “Ready”, then set the test device’s power supply voltage.
• Connect the external DC power supply to the DC interface on the rear panel of the analyzer, and adjust the output voltage of the regulated power supply to a maximum of 12V (It is recommended to supply 4V higher than the power supply of the test device), and press the power switch on the rear panel (press down to1 to turn on, press down to  0 to turn off).
• The red and black terminals on the front panel for the power supply output, confirm the output voltage is correct and then connect the test device’s positive and negative.
• Click the “start” button on PC Software, click the “Auto Zoom” button, you can see the waveform changes of voltage and current.

MT950 User Manual V1.0

• Click the “Pause” and “Continue” buttons to pause the automatic refresh of the chart’s current waveform, which is convenient for viewing and analyzing.
• “Pause” does not stop the current data collection and recording, but the screen displays pause, and the graph and waveform do not change dynamically.
• Click “Continue”, the screen resumes to update and scroll, and automatically moves to the latest real-time data location.

Automatic waveform zoom

• If the current measurement range exceeds the graph representation range, click the auto-zoom button.
• The system will automatically adjust the current coordinate ratio to display the chart waveform.

Zoom in and out of the waveform via mouse roll

• You can specify the mouse roll to zoom in or out on the time axis (horizontal axis) or the current axis (vertical axis) through the setting bar on the right.
• Whether it is horizontal or vertical zooming, the point where the mouse cursor is located is the fixed point, which makes it easier to track and view the waveform details.
• In the static state of the waveform (stop and pause state), you can pan the waveform by dragging the mouse.

Display Ratio

Through the drop-down list space in the display scale setting column on the right, you can easily select the display scale of the waveform on the time and current axis.

NOTE:
The sampling frequency of the analyzer is fixed and will not change due to the adjustment of the display ratio. Different time scale gears are the average calculation results.
For example: select the 100ms time file, a point on the screen represents 100ms time, calculated according to the sampling frequency of 10kHz, this point is the result of the average calculation of 1000 sampling points.
That is to say, although the large-granularity time display ratio scale loses the waveform details, the current (power consumption) value expressed at each point is still an accurate average value that maintains the 10kHz sampling frequency.

Statistical area description

• The real-time display is the real-time current, which is the average current in the last 1 second
• The overall display is the average current from the start to the current time
• The window statistics display the average current within the range of the current screen chart, pay attention to the specific duration and the time display set on the right
• The scale gear is related to the zoom of the time axis
• Recent statistics show the statistical data from the time specified by the user to the current time. The recent time is specified in the setting bar on the right
• The cursor statistics display the statistical data within the cursor range indicated by the dotted line on the screen, which is also affected by the time scale file and time zoom. Refer to the following for the specification method of the cursor range
• The voltage shows the current-voltage

Interval settings and cursor definition

• The interval setting area on the right can set the duration of the recent and cursor statistics. For example, if the recent duration is set to 20s, the data displayed in the recent statistics window at the bottom of the graph waveform is the average result from 20s ago to the current time. The recent duration can be specified as any value that needs to be tracked and observed, and the time unit is seconds.

• You can specify a percentage within the horizontal axis of the chart (the value range is 0 to 100) to display the dotted screen cursor line. If only two cursor lines are set to be displayed, the statistical value of the cursor statistics window on the lower side displays the statistical results between the two cursor lines. If only one cursor line is specified,  the cursor statistics window will display the statistical results from the cursor line to the rightmost area of the waveform.

• A more convenient way to set the cursor is to directly right-click the waveform area to set the cursor line, and the cursor line will be displayed at the right-clicked position.
  Right-click again and the second one appears, right-click three times to hide the cursor, and so on.

• The cursor can be moved by dragging with the mouse. The result of cursor statistics is affected by both time scale and zoom.
