GODIYMODULESADF4351 Signal Source Variable-Frequency Oscillator Signal Generator 35MHz to 4000MHz Digital LCD Display DC 4.5V-5.5V
Main highlights- To end the scan, simply press the "+ +" - "button or the" ok "button. The" ok "button is the exit control button. Click to launch and press again to stop the transmission. The launch behavior caused by "+ +" or "-" requires two "ok" s to end the launch behavior. This product is in the upper right corner of the screen when there is output emission behavior. The corner will appear ">>", button "c" will end the broadcast and the frequency will be zero.
- This product operation keyboard has 15 ppt keys, 0 keys, 9 numeric keys, 10, "+ +" and "-" keys that adjust the frequency to use, and also generate emission output behavior. Press the "+ +" or "-" key to add 1 kHz or lose 1 kHz for the primitive frequency output. Press and hold "+ +" or "-" for more than 1 second, continuous or continuous reduction will occur.
- The scanning mode is 1 khz at 35 mhz ~ 138 mhz; 10 khz at 138 mhz ~ 550 mhz; 100 khz at 550 mhz ~ 4000 mhz.
- Supply voltage: dc 4.5 v-5.5 v, please note that this machine has no built-in voltage regulator unit, it should not supply over the voltage range
- Standby current: <25ma Emission current: <150ma Output impedance: 50 ohms Output frequency range: 35 mhz-4000 mhz Output step: 1 khz-8 khz Output power: -1dbm (w) @ 150 mhz (absolute value of test power) approx. 1 mW
