Basic Operations

Start a Measurement

Set the frequency range (e.g., using STIMULUS START/STOP or CENTER/SPAN parameters).
Perform calibration (refer to the Calibration chapter for details).

Select Display Trace and Format/Channel

The DISPLAY TRACE menu allows you to activate or deactivate display curves. When a curve's name background color matches its curve color, it is active. The FORMAT, SCALE, and CHANNEL options are specific to the active curve.

Use DISPLAY SCALE to adjust the curve's scale.
Use DISPLAY CHANNEL to select the measured port.
You can change display format and channel selection at any time. In normal test mode, tap the right screen area or press the multifunctional switch to access the menu. Tap the screen or rotate the switch to select menu items.
Parameters like DISPLAY FORMAT/CHANNEL and CAL SAVE 0/1/2/3/4 can be selected and saved.

Setting the Frequency Range

The frequency range of a channel is defined by three parameters: Start Frequency, Center Frequency, and Stop Frequency. Adjusting one parameter automatically updates the others to maintain relationships.

Formulas:
fcenter = (fstart + fstop) / 2
fspan = fstop - fstart (where fspan is the SPAN)

Usage 1: Setting Center Frequency

Navigate to STIMULUS CENTER in the menu. The center frequency and sweep span values will display on the grid. Use the soft keyboard to enter values.

Note: Start and stop frequencies vary with center frequency changes when the span is constant. In Zero Span mode, all three frequencies (start, stop, center) are identical.

Usage 2: Setting Frequency Span

Navigate to STIMULUS SPAN in the menu. The center frequency and sweep span values will display. Use the soft keyboard to enter values.

Note: Span and center frequency vary with start frequency when the span is not at its minimum. In Zero Span, all frequencies are identical.

Usage 3: Setting Start/Stop Frequency

Navigate to STIMULUS START or STIMULUS STOP in the menu. The start and stop frequency values will display. Use the soft keyboard to enter values.

Note: Span and center frequency vary with stop frequency. Span changes can affect other system parameters. In Zero Span, all frequencies are identical.

Calibration and Normalization

Accurate measurements require RF calibration (SOLT - Short, Open, Load, Thru). The DeepVNA 101 includes calibration parts: open, short, load, and an RG316 RF cable.

Calibration data is saved as user calibration data and can be stored in statuses 0/1/2/3/4. This data is automatically loaded on the next boot or can be recalled via the RECALL menu.

Calibration Steps Summary

Open the CAL menu and press RESET.
Open the CALIBRATE menu.
Connect SMA Open ⚪ to PORT1, wait for screen stabilization (over 3 seconds), and press OPEN.
Connect SMA Short ?️ to PORT1, wait for screen stabilization (over 3 seconds), and press SHORT.
Connect SMA Load ⚖️ to PORT1, wait for screen stabilization (over 3 seconds), and press LOAD.
Connect SMA Load ⚖️ to PORT1, connect a second Load to PORT2, wait for screen stabilization (over 3 seconds), and press ISOLN. (If a second Load is unavailable, leave PORT2 open).
Connect RF cable from PORT1 to PORT2, wait for screen stabilization (over 3 seconds), and press THRU.
Press DONE and save to one of the statuses (0/1/2/3/4).

Notes:

If existing calibration data is present, press RESET first to clear it before recalibrating.
If an error occurs, restart the calibration process from RESET.

Maintenance and Upgrades

Calibrate the Touch Screen

Enter menu: CONFIG → TOUCH CAL.
Use a toothpick or sharp object to click the center of the cross ➕ that appears.
Enter menu: CONFIG → SAVE.

Upgrade the Firmware

Download: www.deepelec.com

Download and unzip the update package. You should find update.bin and update.all files.
Connect your DeepVNA 101 to a PC using a Type-C USB cable. Press and hold the middle button while powering up the device. The LCD will show a prompt indicating the boot-loader is active.
On the PC, the device will appear as a disk drive. Copy the update.bin and update.all files into the root directory ? of this drive.
Power the device off and on again. The boot-loader will run automatically to update your DeepVNA 101. Re-power for normal operation.

Add Call Sign Display

Connect your DeepVNA 101 to a PC using a Type-C USB cable. Press and hold the selector switch while powering up. The LCD will indicate the boot-loader is active.
On the PC, the device appears as a disk drive. Copy your callsign.txt file into the root directory ? of this disk, then re-power the device.

Change Language

If your DeepVNA 101 is set to Chinese or you wish to change the language:

Follow the steps shown in the figure (typically involves navigating to Settings → Language → English).
Example path: 设置 (Settings) → 语言 (Language) → 英文 (English).

Use PC Software and Install Drivers

Driver Download: http://deepelec.com/files/en.stsw-stm32102.zip

Install the appropriate 32 or 64-bit driver. Turn on the device, connect it to any USB port, and wait for the "Installing driver" message to complete.

While official PC software is not yet released, the use of nanovna-saver (by Rune B. Broberg) is recommended for NanoVNA PC software functionality. Download it from: https://github.com/mihtjel/nanovna-saver
