RigExpert REAMP User Manual 1.INTRO
The REAMP POWER CONSUMPTION LOGGER (REAMP) is designed to test the power consumption modes of various devices powered by 1.8V to 5V DC. It can also supply voltage to the device under test within a wide selection range of 1.8V to 5.2V with a 50mV step. REAMP allows users to measure instantaneous values of the consumption current and voltage, record them in a log file, mark the signals amplitude, determine the signal period, perform values average over a specified time interval, calculate the duration of an autonomous source DUT operation, control data recording, and report data in graphical and tabular forms (*.xlsx, *.CSV). Users can also work with archived log files and more. The current measurement range is 10µA to 1A (100dB) and there are two input channels for voltage measurement at the user's DUT points of interest. The range of voltage measurement is 20mV to 5V. The sampling frequency is 10 Hz to 10 kHz. This device is particularly useful for developers of IOT, USB, and other devices where minimizing power consumption during sleep mode is crucial. It is powered and operated when connected to a computer via a USB port. 2. FUNCTIONAL DIAGRAM AND CONNECTION Functional and connection diagram of REAMP device is shown on Figure 2.1.

Connector pin assignments: · DUT -- device under test · Vout -- + 5 V (1.8...5.2 V), current measurement channel · SYNC (optional) output is flag for synchronization of the external device operation with the measurement starting process ("1" - start of measurement, "0" - stop of measurement) · TRIG (optional) --input is flag from the external source for the measurement start ("1" - start of measurement, "0 - stop of measurement) · Vin1 -- 1st voltage measurement channel · Vin2 -- 2nd voltage measurement channel · GND ground
3. PREPARING FOR MEASUREMENTS
A 6-position connector (Fig. 2.1) on the REAMP front panel is connected to the DUT by test probes included in the kit. To measure the current: 1) Connect Vout of REAMP to positive ("+") bus of power supply lines of DUT and and connect GND
of REAMP to negative ("-") bus of power supply lines of DUT 2) Run the REAMP program on your PC, which is compatible with Windows, Linux, and MacOS
operating systems. The program can be downloaded on your PC from https://rigexpert.com/files/software/ReAmp/ 3) Connect REAMP to your PC with a TYPE ATYPE B USB cable 4) The circuit is now ready for measurements using the user interface of the REAMP program Installation instructions for the REAMP program can be found in section 4. To measure the voltage: 1) Connect Vin1 and/or Vin2 of REAMP to the positive ("+") input of measurement point (controller/processor/sensor/device under test) and connect GND of REAMP to the negative ("-") input of measurement point 2) Run the REAMP program on your PC, which is compatible with Windows, Linux, and MacOS operating systems. The program can be downloaded from https://rigexpert.com/files/software/ReAmp/ on your PC 3) Connect REAMP to your PC with a TYPE ATYPE B USB cable 4) The circuit is now ready for measurements using the user interface of the REAMP program. Installation instructions for the REAMP program can be found in section 4. The DUT can be powered from the REAMP. The two connections are required for its operation: Vout to "+" DUT and GND to "-" DUT. This setup allows for measuring the current consumption of the DUT. Since a USB port can only provide up to 500 mA of current output, the REAMP is equipped with a built-in Li-ion battery to ensure sufficient power. The battery is automatically recharged through a USB port using a charge algorithm of CC-CV at 250 mA current. When the battery is fully discharged (below 3 V), the power source will switch to the USB for recharging. It's important to note that while the battery is being charged, a portion of the USB port's current will be used for this purpose, leaving only the remaining portion of the total 500 mA current available for powering the DUT.

Quick navigation bar for finding event/points When dealing with a large data file, the event detector helps to identify and analyze peaks. By setting the peaks threshold, you can view anomalies and click on them in the Navigate bar to directly access the corresponding measurement segment. To zoom, hold the left mouse button and highlight the zoom area on the scale with the cursor. To reset the zoom, simply click . ZOOMing data on the data diagram To zoom, position the cursor on the measuring axis and use the mouse wheel to adjust the zoom level. Double-clicking the axis will return it to the default scale. You can also use the mouse to select a specific portion of data for a closer view. Quick navigation bar and ZOOMing works in data analyze mode when active measurement is stopped.
5. BASIC OPERATION
The device has two operation modes: · Logging mode - takes instantaneous measurements and records them in a log file. In this
mode, configuration and control functions (except for the "STOP" button) and "Show Report" are not available · Data analyze mode - allows viewing recorded information, saving log files, time scaling, calculating the discharge time of the DUT battery for a given current consumption profile, and operating with historical data (log files)

RigExpert REAMP User Manual Converter mode - enables the conversion of saved log files to table format (*.xlsx or *.CVS) using the REAMP converter application from the installed REAMP-logger package.
To start working in measurement mode: · Connect the DUT to REAMP as shown in diagram (Fig. 2.1.) · Run the REAMP-logger on your PC · Connect the REAMP to the PC · Set power voltage (mV) · Make settings in accordance with subsections 5.1-5.4.
To use analyze mode in REAMP logger, open the saved files or stop the measurement mode. The data analysis program functions are described in subsections 5.5. To convert data, pen REAPM-converter, select the log file on the PC, choose the desired output format and time format, then click "Start". 5.1. POWER CONTROL Set output power voltage (Figure 5.1). If the DUT consumes the current less than 500 mA, then select option "Vusb Vin" in the "Switch Vin" field, otherwise select "Vbat Vin".
FIGURE 5.1: VOLTAGE SETS
To delay the start of power or logging select the desired delay in the "Sync related" field and choose either TRIG or Logging. If you don't need a delayed recording or power supply, enter 0 in the "Sync related" field and then click "Apply". After that, you can choose the type of power supply: Permanent for immediate power to the device under test (DUT) or Delayed for a delayed power supply (refer to Figure 5.2). Once you've made your selection, click "Set" and the power supply will be provided to the DUT.

5.2. SYNC CONTROL
This function is designed for specific measurements when necessary. The "SYNC" field is displayed in Figure 5.1. Configuration of SYNC should be done before starting the measurement or after pressing the "STOP" button. You can choose the power source: either USB or battery. Set the output voltage within the range of 1800mV to 5200mV. To apply a voltage to the DUT, you have two options: ·Keep it always on ·Start with a delay linked to the measurement process. The delay time is 100 measurement samples but no more than 100ms--refer to Figure 5.3. Press the Apply button to activate the new settings.

5.3. APPLYING OF TRIGGER-SIGNAL WITH SYNCHRONIZE-SIGNAL In certain cases, when studying the DUT sleep modes, it may be necessary to trigger measurements synchronously (or with a specific delay) with a process taking place in the DUT circuit. Or vice versa, the gauge must trigger a process synchronously (or with a delay) relative to the start of measurements. For this purpose, the REAMP device has TRIG and SYNC signals.
5.3.1. TRIGGERING (TRIG) SIGNAL
This function is for specific measurements, if it`s needed.
Configurating of TRIG should be before measurement starting or after "STOP" button is pushed.
