1. Introduction
The DEEPELEC DeepVNA 101 HW3.2 is a handheld vector network analyzer designed for comprehensive analysis of HF/VHF/UHF antennas and circuits. This device allows for precise measurement of S-parameters, transmission and reflection characteristics, insertion loss, return loss, fault location (TDR function), antenna standing wave ratio (SWR), impedance, and filter response.
This model is an upgrade from the NanoVNA-F, featuring several key improvements:
- User controls have been enhanced with a rotary encoder for more convenient and smooth operation.
- A new Real-Time Clock (RTC) circuit has been added, providing real-time clock and perpetual calendar functions.
- S21 insertion loss/filter measurement performance has been optimized, offering a larger dynamic range.
The device runs on firmware version 1.0.4, which includes additional features such as:
- Measurement data files are automatically named in the format YYMMDD_HHMMSS.
- Frequency settings can be configured using either start/end frequencies or center span mode.
- The boot sound can be toggled on or off.
The DeepVNA 101 HW3.2 is available with either an Aluminum metal shell or an ABS black plastic shell. Aside from the shell material, all other parameters, performance, and accessories are identical between the two versions.

4.3 Screen Protector Note
The DeepVNA 101 uses a resistive touch screen. The working principle relies on pressure sensing. Installing a screen protector may affect the touch screen's operation. It is recommended not to install a screen protector unless absolutely necessary to maintain optimal touch sensitivity.
5. Operating Instructions
5.1 Power On/Off
To power on the device, slide the ON/OFF switch located on the side. To power off, slide the switch back to the OFF position.
5.2 Navigation and Control
The DeepVNA 101 can be controlled using its 4.3-inch resistive touch screen and the rotary encoder. The rotary encoder provides a more convenient and smooth control experience for menu navigation and parameter adjustment.

6. Maintenance
6.1 Cleaning
To clean the device, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the screen or casing.
6.2 Storage
When not in use, store the DeepVNA 101 in its protective EVA bag to prevent dust and physical damage. Store in a cool, dry place away from direct sunlight and extreme temperatures.
6.3 Screen Care
As noted in the setup guide, the resistive touch screen's functionality relies on pressure. While a screen protector is included, installing it may impact touch sensitivity. Handle the screen with care and use the provided resistive screen touch pen for optimal interaction.
7. Troubleshooting
- Device not powering on: Ensure the battery is charged. Connect the device to a power source using the USB Type-C cable and allow it to charge for a period before attempting to power on again.
- Inaccurate measurements: Perform a full calibration using the OPEN, SHORT, and LOAD calibration pieces. Ensure all cables and connectors are securely attached and in good condition. Verify that the correct frequency range and measurement parameters are selected.
- Touch screen unresponsive: If a screen protector is installed, try removing it as it may interfere with the resistive touch functionality. Ensure the screen is clean and free from debris. Use the provided touch pen for precise input.
- Data not saving correctly: Check the device's internal memory status. Ensure the date and time are set correctly via the RTC function, as this affects file naming.
- General instability: If the device behaves unexpectedly, try restarting it. Ensure the firmware is up to date by checking the official support website.
