Screen size: 4.3 inches
Battery: 1 lithium battery, 2500mAh (included)
Spectrum display range: 35M-4400MHz
Input impedance: 50 ohms
RBW: 10khz, 50khz, 100khz, 200khz, 500khz, a total of 5 levels adjustable
Screen scan points: 700 points
Scan span: 7M (10KHz), 35M (50KHz), 70M (100KHz), 140M (200KHz), 350M (500KHz)
dBm range: -70dB~10dB (supports manual adjustment of calibration amplitude). There is no amp lifier circuit inside this machine. If you need to measure small signals, you need an external amplifier.

notes:
This product uses the local oscillator signal and the external test signal to obtain the difference frequency signal, and calculates the amplitude of the external test signal through the detector. Using a high-precision VCO source, heterodyne signal frequencies can be measured very accurately. Due to the large scanning range (35M-4400M), there is no detection circuit specifically for external measurement signals due to cost and other factors, resulting in possible errors in the measurement amplitude. Therefore, the product adds magnification and displacement parameters, and users can adjust the displayed waveform by themselves. The amplitude display is adjusted and calibrated.
