Description U/V UHF VHF Spectrum Analyzer Dual Band with Tracking Source 136-173MHz & 400-470MHz


- Frequency Range: 136-173MHz & 400-470MHz
- Spectrum Dynamic Range: -127dBm-0dBm (practical sensitivity: -115dBm to 0dBm)
- Resolution: 1dB
- Tracking Source Output Power: ≈ -38 dBm
- Interface: BNC-F
- Power: External Power Supply DC 8 - 12V

- The upper right corner of the spectrum shows the spectrum mode, the display tracking for the spectrum plus tracking mode, which can be switched by long press F1
- The First Line: shows the center frequency & center frequency power
- The Second Line: captures the strongest or weakest frequency, or the specified frequency and power (shows the strongest frequency in capture mode, show the weakest frequency in spectrum plus tracking mode, display the frequency and power of specified modes (please refer to “Steps to Adjust the Duplexer ")
Steps to Adjust the Duplexer:
- As adjusting the duplexer, the curve is only for reference. And the exact value depends on the power after the frequency in the first line.
- Before adjusting the duplexer, you need to connect the OUT and IN ports via the connecting cable of the duplexer. Adjust the frequency of the first line to a desired frequency, have a look at the power value and write it down to complete straight-through calibration. And this value is about -30dbm. Connect it to the duplexer, if the value becomes -100dbm, that is, the isolation degrees of the duplexer is -70db.
- The Third Line: frequency range (center frequency plus or minus), stepped frequency
- F1: cursor movement center frequency, frequency range, step cycle selection (long press to switch between spectrum and tracking mode)
- F2: Backspace
- The Cursor Points to the Center Frequency:
Using numeric keys to direct input or using up and down keys to adjust frequency step by step
F3 F4: Adjust the frequency every 1M
- The Cursor Points to the Frequency Range:
The value is based on the center frequency plus or minus the range, for example: 0128000 as the center plus or minus 12.8 M, that is, the range is 25.6M
Using numeric keys to direct input or using up and down keys increase or decrease the range
- The Cursor Points to the Step: using the number keys to directly input or using the up and down keys to adjust the step change in 5K (The scan range will be slightly changed to fit the size of the grid)
