This document describes how to use the QCLI app to measure current consumption on the QCC730 in various operation modes.
## Test environment

The QCC730 current is measured in the following environment.
Table : Power measurement environment setup
| **Hardware** | QCC730M Evaluation Kit (EVK). |
| --- | --- |
| **Environment** | Room temperature.
Measurements are taken within a shield room. |
| **Test instrument** | Keysight N6705C DC power analyzer mainframe for dynamic measurements, with 4-wire sensing disabled. |
## Rework the EVK and connect the power analyzer

Follow these steps to rework the QCC730M EVK and connect it to the power analyzer.
1. Remove jumper J3.PIN15 to PIN16 to disconnect the 32.768 K OSC, which isn't in use but still draws current from VDDIO rail.
2. Select VDDIO as 1V8.
3. Configure two channels of the Keysight N6705C DC power analyzer as Current Measurement mode.
4. Connect the EVK and the N6705C as shown in [Figure : QCC730M EVK setup](https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_tests.html#power_measurement_points__fig_evk_3).

## Set up console connection

Follow these steps to set up the console connection:
1. Connect the QCC730M EVK to a Windows PC using a USB-C cable.
The board powers on automatically.
2. Identify the COM ports assigned to the QCC730M EVK in **Device Manager**.
The QCC730M EVK is assigned two COM ports when connected to a PC. Typically, the higher-numbered COM port is used. However, if that port doesn’t work, use the other port in the following steps.
3. In the serial communication tool, establish a connection to the higher-numbered COM port with the following settings:
- **Baud rate**: 115200
- **Data bits**: 8
- **Parity**: None
- **Stop bits**: 1
- **Flow control**: None

Use the QCLI app to measure power consumption on QCC730M EVK in the following operation modes:
- Soft-off: The board is shut down using software while system power remains on. The board can wake up through a timer or GPIO signal.
- Suspends to RAM (S2RAM) without Wi-Fi: The board enters S2RAM with Wi-Fi disabled. The board can wake up through a timer or GPIO signal.
- Beacon mode power save (BMPS): The board primarily remains in S2RAM and periodically wakes during the delivery traffic indication map (DTIM) interval to maintain the Wi‑Fi connection.
- Idle mode power save (IMPS): The board enters S2RAM when Wi-Fi is disconnected.
- Active: The board is active with one of the following Wi-Fi traffic types:
- TCP Rx
- TCP Tx
- UDP Rx
- UDP Tx
