IAR I-scope

I-scope is a small probe that adds current and voltage measurement capabilities to I-jet.

The measurements can be done at any designated points on the target board and are displayed in real-time by the C-SPY Debugger in IAR Embedded Workbench for ARM.

Key features

• I-scope measures current and voltages and sends it to I-jet, which synchronizes the data with the program counter of the running application.
• The data can be graphed and profiled in real time and analyzed using the C-SPY Debugger in IAR Embedded Workbench for ARM.
• The current sensing is done by connecting two differential current measurement leads across a shunt resistor on the target board.
• The power analysis can for example be used to:
   - Reveal the power consumption of individual functions and peripherals
   - Identify I/O activities that cause current spikes
   - Diagnose low power mode
   - Investigate MCU frequency and core voltage power savings
   - Find conflicting hardware setup
   - Reduce RF emissions by identifying and eliminating unwanted current spikes
   - Measure and compare battery consumption in various MCU sleep modes

Specifications

• I+ and I- differential voltage, 110mV full scale across shunt resistor

Please note: I-scope is used in combination with I-jet
