Measuring Current Consumption in Different Power Modes
www.cypress.com Document No. 002-14914 Rev. *C 3
3 Overview and Orientation
3.1 Overview
This document provides procedures for measuring the amount of current consumed by BCM4324/BCM4334
devices while in different modes. The modes for which such procedures are provided include the following:
■ Sleep mode
■ Standard 1.28s Inquiry Scan mode
■ Standard 2.56s Inquiry Scan mode
■ Standard Page Scan mode
■ SNIFF_500ms_Master mode
■ SNIFF_500ms_Slave mode
■ HV(3/2) for DUT as Master mode
■ HV(3/2) for DUT as Slave mode
■ EV(4/5) eSCO for DUT as Master mode
■ EV(4/5) eSCO for DUT as Slave mode
■ Throughput ACL, 3DH5 mode
Note: For information regarding the measurement of current consumption of Bluetooth Low Energy devices, refer
to the document cited in Reference [1] on page 2 .
3.2 Orientation
The following provides information that the user needs to know before starting to make current consumption mea-
surements:
■ Cypress BlueTool™ is used to place the device under test (DUT) in each mode. To obtain the latest version,
contact your Cypress representative.
■ The equipment needed for making power consumption measurements is described in System Requirements
on page 3 .
■ It is assumed that you are familiar with BlueTool and that you know how to set up and use the equipment
needed for measuring current consumption.
■ The procedure for downloading the BlueTool configuration and minidriver files to the DUT and reference board
is also provided (see
Downloading the Minidriver and Configuration File on page 4 ). You must download these
files to the devices before you begin setting the various modes.
■ In this document, HCI control: com4 refers to the DUT, and HCI Control: com5 refers to the reference board.
The actual COM port number may be different for each test system.
■ The number key shortcuts to switch to the various HCI command lists refer to the number keys above the letter
keys on the keyboard.
■ WLAN core is in reset (WL_REG_ON = low) for all measurements.
4 Test Setup
4.1 System Requirements
The system requirements are as follows:
■ Host system
