Pass System Automatic Fixed-Frequency Test

Interface Overview

EUT Auto V4 uses a left navigation bar layout, with the version number and documentation link shown at the top. The navigation bar has four pages:

PageFunction
DashboardMain control page: configure connection parameters and start fixed-frequency
SettingsConfigure RF parameter presets for each chip
Manual ControlManually send fixed-frequency commands for debugging and verification
Self-DefinedCustomize fixed-frequency command templates for new chips

Basic Operations


Step 1: After connecting the hardware devices, open EUT Auto and go to the Dashboard page

v4_dashboard

The center of the Dashboard page is divided into two card areas:

Host card (connection between EUT Auto and the TST PASS system)

  1. In the IP field, select the IP of the current computer (if the system has multiple IP addresses, select the one on the same subnet as the TSTPASS system, usually 10.0.0.xx)
  2. In the Port field, fill in the port number, default 5055 (when controlling multiple samples for automatic fixed-frequency on the same computer, fill in a different Port for each window to distinguish the samples)

EUT card (connection between EUT Auto and the sample)

  1. In the Vendor field select the chip manufacturer, then select the chip model in the Chip field; after selection, the interface shows usage tips for that chip (driver, pre-processing notes, etc.), and the baud rate automatically switches to the chip's default value
  2. In the Interface field, select the communication interface type with the sample:
    • Serial: select the corresponding Port (COM port) and Baud (baud rate)
    • ADB: select the corresponding ADB Device
    • USB: select the corresponding USB Device
    • SSH / Telnet / IPOP: fill in Server (IP address), Username and Password
    • MP DLL / HQA DLL / AC DLL (DLL direct call): dedicated to MediaTek and Realtek USB adapter solutions; the software switches automatically when the corresponding chip is selected, no manual selection needed. For MediaTek HQA, leaving Host empty means local USB/PCIe/SDIO auto-detection, while filling in an IP controls an AP SoC (OpenWrt router board) via Ethernet

Start control

  1. Click the green ▶ button to start automatic fixed-frequency, click the pink ⬛ button to stop
  2. The log area on the right shows the fixed-frequency command traffic in real time; click CLEAR to clear the log, or REFRESH to refresh the available COM port/device lists

Step 2: Configure the corresponding EUT Auto Setting on the Settings page

v4_settings

  1. In the Vendor and Chip drop-down boxes at the top, select the chip model to configure (this selection is linked with the Dashboard page; the chip selected on the Dashboard is automatically synced here)
  2. In the left sidebar, select the RF function to set; the list shows only the technologies actually supported by the chip (Wi-Fi 2.4G / Wi-Fi 5G / Wi-Fi 6G / Bluetooth / BLE)
  3. Set the corresponding power and other parameters according to project requirements. For Wi-Fi technologies, power can be set per modulation and bandwidth for low/middle/high channels; for Bluetooth technologies, power can be set per low/middle/high channel; leave empty (0) to use the default power
  4. Click the Save button to save the settings, or Reset to restore defaults
  5. Return to the Dashboard page and click ▶ to start fixed-frequency

Step 3: Set the corresponding EUT Auto IP in the TST PASS system

Note:

Entering the EUT Auto IP is considered as enabling automatic fixed-frequency testing, and subsequent tests can proceed normally without pop-up fixed-frequency prompts.

If subsequent tests do not require automatic fixed-frequency testing, please delete the IP here.

Support for Simultaneous Automatic Fixed-Frequency Testing of Multiple Samples

  1. Click EUT Auto.exe to open multiple automatic fixed-frequency windows simultaneously
  2. Provided the samples are correctly set up and connected, different automatic fixed-frequency windows can select the corresponding chip type
  3. Click the ▶ button for each window one by one to begin automatic fixed-frequency testing

Note:

  1. When performing automatic fixed-frequency testing on multiple samples simultaneously, different Host Ports must be set to avoid fixed-frequency conflicts.
  2. Some samples may require pre-configuration depending on the actual usage scenario (e.g. Airoha and BES solutions require pre-processing).
  3. When performing automatic fixed-frequency testing on multiple samples simultaneously, pausing or configuring one sample individually does not affect the automatic fixed-frequency testing of other samples.
  4. The samples supported by the automatic fixed-frequency software are continuously being updated. For details, please see Supported Samples

Manual Control

v4_manual_control

The Manual Control page allows sending fixed-frequency commands to the sample directly and manually, without connecting to the TST PASS system. It is suitable for debugging and verification.

  1. At the top of the page, select the chip (Vendor + Chip) and interface type (same as the Dashboard), then click Connect to connect the sample
  2. Select the test technology (the list shows only technologies supported by the chip), standard (e.g. 802.11b/g/n/ax), bandwidth, channel and data rate; for Wi-Fi technologies you can also choose the SISO / MIMO TX type
  3. Click the corresponding button to send commands directly: TX (modulated transmission), CW (carrier transmission), RX (receive), HOPP (frequency-hopping transmission), STOP (stop)
  4. The log area at the bottom shows the command traffic

Note: Manual Control and the Dashboard's automatic fixed-frequency are mutually exclusive; manual control cannot be used while automatic fixed-frequency is running, and vice versa.

Self-Defined (Custom Chip)

v4_self_defined

The Self-Defined page allows users to configure fixed-frequency commands for custom chips, suitable for new chip solutions not yet included in the list. The configuration is done through a three-step wizard:

  1. Technology and standard selection: check the technologies to support (Wi-Fi 2.4G/5G/6G, Bluetooth, BLE) and the corresponding bandwidths/packet types, and choose whether to support carrier wave transmission and the TX/RX/HOPP modes
  2. Variable configuration: set the antenna mapping, channel format (decimal/hexadecimal) and power values per technology-bandwidth combination
  3. Command templates: for each technology combination, fill in the actual commands sent to the chip, using {ch}, {ant}, {bw}, {power} as placeholders; separate multiple commands with ;|

⚠️ Note: The Self-Defined feature is still under debugging and is not recommended for formal testing yet.
