I-scope

I-scope adds current and voltage measurement capabilities to I-jet and I-jet Trace. 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.

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 C-SPY. The current sensing is done by connecting two differential current measurement leads across a shunt resistor on the target board.

Use the power analysis 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
  • One differential current channel, 0-6V common mode
  • Three voltage channels, 0-6V
  • Sampling rate up to 200 kHz with 12 bit resolution
  • Includes one MIPI-20 flat cable for attaching to the I-jet
  • Includes 6 flying test leads and 6 grabbers
  • Supports all ARM cores

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