Full-band Measurement: Covering the measurement ranges from 10M to 900M for transmitting frequency and the reception ranges of radio frequency signal generator from 1MHz to 470MHz, it supports the measurement of both analogue and standard digital subtones from 50Hz to 260Hz, which makes it suitable for comprehensive debugging of all kinds of veryhigh frequency and ultrahigh frequency hand-held interphones. Duplex Mode and Repeater Test Optimization: Designed for the debugging and measurement of V repeaters and frequency modulation radios, the signal generator can operate in duplex mode. Even if the machine under test is in the transmitting state, it not affect the generator's operation. It can also be used for measurements in the repeater state. The generator features two working modes design, allowing for a switch between signal source mode and frequency meter mode. High Precise & Multi-functional Operation Interface: This device provides an intuitive digital display and function button operation. It supports precise adjustment and cycle switching of frequency, power, sub-tone, and modulation tone. It also allows for the setting of analogue and digital subtitles, as well as frequency setting, to meet the needs of detailed debugging. Wide Dynamic Ranges and High Sensitivity Reception: This device has a high reception measurement capacity, supporting an output level from -132dBm to -90dBm. It offers selectable single-tone modulation output at 1KHz, 2KHz, and 3KHz, with an output modulation of 3K, which ensures comprehensive testing from weak to strong signals, thereby improving debugging efficiency and accuracy. Portable Design: and portable, this device comes with a detachable handle, making it easy to install and carry. It operates on 8-12VDC and has low power consumption, making it suitable for on-site debugging and portable operation, which ensures professional-level test performance.
