YOKOGAWA AQ23011A/AQ23012A Modular Framework Equipment

Product positioning and core applications

AQ23011A/AQ23012A is a modular framework device that requires the use of AQ23811A and other source measurement modules (SMUs). Its core function is to achieve high-precision output (source function) and measurement (measurement function) of voltage/current, supporting multi-channel synchronous control and complex scanning analysis. The main application scenarios include:

Semiconductor testing: testing of chip pin voltage/current characteristics, measurement of MOSFET threshold voltage.

Electronic component verification: impedance characteristic analysis of resistors/capacitors/inductors, and forward voltage drop testing of diodes.

Calibration of new energy devices: collection of lithium battery charge and discharge curves, scanning of photovoltaic module IV characteristics.

2. Hardware structure and component functions

(1) Core components of the front panel

Component name, location, and function

There are 9 slots on the left side of the module slot (AQ23011A/AQ23012A universal), used for installing modules such as AQ23811A, slot numbers 1-9

10.1-inch color LCD (1280 × 800 pixels) in the center of the touch screen display, supporting touch operation (menu navigation, parameter settings)

The F1~F6 keys at the bottom of the function soft key screen correspond to menu options and dynamically change with the interface

Each module on the front panel corresponds to one trigger input/output terminal (TTL level, negative logic) for external trigger signal interaction

There are two USB 3.0 ports on the right side of the USB host interface, which can be inserted into a USB flash drive/portable hard drive to save data, or connected to a mouse/keyboard

Power button on the right side of the power and status light (with LED indicator light, green constant light for normal), error indicator light (red flashing for fault)

(2) Core components of the rear panel

Component Name Function

AC power interface connected to dedicated power cord (input 100~240 VAC, 50/60 Hz, maximum power consumption 120 VA)

Ethernet interface RJ45 interface, supporting TCP/IP protocol, used for remote control (HiSLIP/RawSocket) or network file sharing

External trigger interfaces Trig IN1/Trig IN2 (BNC interface, TTL level), Trig OUT1/Trig OUT2 (BNC interface), used for external trigger synchronization

The Remote Interlock terminal of the interlocking interface requires a dedicated plug (A1288JA) to enable module output and ensure safety

GP-IB interface optional interface (requires module configuration), used for remote control of traditional instruments

USB device interface USB Type-B interface, connected to PC for high-speed data transfer or remote control

Basic operation process

1. Startup and initialization settings

(1) Power on preparation

Hardware connection: Confirm that the framework is powered off, install the AQ23811A module (insert it into the slot rail and lock it), connect the AC power cord, and turn on the power switch on the rear panel.

Self check and startup: automatic framework detection module after startup DRAM、 File system, after passing self-test, enters the main interface (summary view); If the self-test fails (such as module not recognized), the screen will display an error code (such as E021: Slot 1 module abnormal), and the module needs to be reinstalled or repaired.

Restore default settings: Press the "Function icon" → "System" → "Reset Frame to factory default" in the upper left corner of the screen, confirm and restore the factory settings (source output turned off, measurement mode default voltage, trigger source set to None).

(2) Module calibration (key steps)

When the AQ23811A module is used for the first time or when the ambient temperature changes by more than ± 10 ℃, zero calibration needs to be performed:
