In the design of this 4.3-inch TFT color LCD screen spectrometer,

I set my goal to achieve the maximum value with the least money.

I chose the most cost-effective chip adf4351 as the reference signal source,

which can accurately measure the frequency value.

Use high-performance mixers and wave detectors with micro-adjustment software parameters to measure the signal amplitude value,

Using stm32f4 series single-chip computer and 4.3-inch color LCD screen,

The black aluminum alloy shell is beautiful and strong.

Come and experience it.

2. Performance indicators

(1). Spectrum display range: 35Mhz-4400Mhz; input impedance: 50 ohms.

(2). RBW: Adjustable at 10kHz, 50KHz, 100kHz, 200kHz and 500KHz.

(3). Screen scanning points: 700.

(4). Scanning span: 7m (10kHz), 35m (50KHz), 70m (100kHz), 140m (200kHz), 350m (500KHz).
