Consumption Measurement Procedure
4.1.2 Wireless CPU
®
Development Kit
The Wireless CPU
®
board used is the Q64 Wireless CPU
®
Development board. This
board can be used to perform consumption measurement with several settings.
The Wireless CPU
®
is only powered by VBATT on the development board. The
Development Kit board is powered by the standalone power supply at VBAT. It is for
this reason that the link between VBATT and VBAT (J103) must be opened (by
removing the solder at the top of board in the SUPPLY area).
¾ VBATT powered by the current measuring power supply (66321B).
¾ VBAT powered by the standalone power supply (AX502).
The R100, R101 resistor, and D101, D103 diode (around the BAT-TEMP connector)
must be removed.
The UART2 link is not used, therefore J501, J503 must be opened (by removing the
solder).
The “LED” should not used, so R103 and R104 resistors must be removed.
The USB link is not used, therefore J801, J802 and J803 must be opened (by
removing the solder).
Around “CONFIG” area, the switch SERVICE must be to OFF position.
The purpose of the settings is to eliminate all bias current from VBATT and to supply
the entire board (except the Wireless CPU) via VBAT only.
The standalone power supply may be set to 4 volts.
4.1.3 SIM cards used
Consumption measurement may be performed with 3-Volt or 1.8-Volt SIM cards.
However, all specified consumption values are for a 3-Volt SIM card.
Caution:
The SIM card is supplied by the Wireless CPU
®
, consumption measurement
results may vary depending on the SIM card.
4.2 Software Configurations
Software configuration for the equipment and Wireless CPU
®
settings.
4.2.1 Wireless CPU
®
Configuration
The Wireless CPU
®
software configuration is simply performed by selecting the
operating mode to be used to perform the measurement.
A description of the operating modes and the procedure used to change operating
mode are given in the appendix of document [4] AT Command Interface Guide for
Open AT
®
Firmware v6.5.
