- Input detection: ≤10dbm
- Background: ≈ -50dBm
- Computer side software: NWT4.11.09 version
- Computer operating system: For win xp, win732, win764, win1032
- Purpose: To measure frequency, do simple amplitude-frequency characteristic analysis of transmission network
- Applicants: Radio enthusiasts, students
- Core components: ATMEGA8A MCU. The output of adf4351 is a rectangular wave, and the amplitude becomes the trigger level. IAM81008, the mixer chip, uses Chinese ps3120 to supply power. IAM81008 is a vulnerable part and is easy to break. Ad8307, power logarithmic detector. Ch340e, a Chinese USB to ttl chip, is extremely cost-effective
- Working principle and concept: difference frequency scanning, low pass (RBW) 200khz
