DESCRIPTION

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. 

It features replaceable modular parts, allowing users to easily swap components if damaged—compatible modules are available in the dedicated SV4401A – 4.4G VNA REPLACEMENT PARTS.

The SV4401A combines high-precision measurements, wide frequency coverage, and a modular design to deliver reliable, long-lasting performance in the field.

  • 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.
