SKU: CH0010006 Categories: , , ,

SV4401A is a handheld Vector Network Analyzer (VNA) with frequency range of 50kHz ~ 4.4GHz. It can be used for S11 and S21 measurements. The S21 dynamic range of SV4401A is 75 dB, while the S11 dynamic range is 50 dB.

NOTE: The SV4401A requires a USB-A to USB-C cable for charging. A cable with USB-C connectors on both ends may not be compatible with the unit’s charging system, which could explain the lack of response when connected.

  • I upgraded my SV4401A to firmware V0.3.1, but I found that the UDisk function doesn’t work with my Mac.The UDisk function isn’t supported for macOS when in upgrade mode. To enter UDisk mode, there are two options: [from the device]either select it from the menu on the main screen or press and hold the Ctrl key while powering on the device to enter upgrade mode.
  • My VNA failed to be switched on while its fully charged?There is a design flaw in the hardware caused this issue however luckily it can be fixed by yourself. Please follow THIS instruction.
  • By mistake I deleted my font file and my VNA couldn’t boot, what should I do?You just need to hook up SV4401A to computer(with the USB cable) with U-disk mode enabled, put the copy of the ‘Alibaba-PuHuiTi-Medium.ttf’ font file back to the system folder in the device. It should be loaded the next time you reboot the device.
  • What should I pay attention to when charging?
    Please be aware that SV4401A cannot be charged by usb-c to usb-c, it has to be usb to usb-c.
  • Is it possible to save user calibration data before performing a factory reset and restore it afterward?
    Yes, when the device is in USB mode, there is a “cal” folder where calibration results are stored. You can back up these files before performing a factory reset and restore them afterward. However, we recommend recalibrating the device after a reset since firmware updates or changes may affect certain parameters. Regular calibration ensures the highest measurement accuracy.
  • Why is my 4401A VNA not charging?
    The SV4401A requires a USB-A to USB-C cable for charging. A cable with USB-C connectors on both ends may not be compatible with the unit’s charging system, which could explain the lack of response when connected.
