ReviewsStep Variable Attenuator

USDR/USDX HF QRP SDR Transceiver SSB/CW Transceiver 8-Band 5W Ham Radio & Handhel Mic

【IRF Tube】Using IRF series transmitting tube to ensure its being durable & can be used to connect to an antenna (instrument base)..
【Lightweight&Cost-saving】The original QCX circuit is greatly simplified, and the installed components are reduced by 50 percent to save you the trouble of complicated transformer windings and wiring procedures..
【Less Power Consumption】Thanks to the EER transmitter E-level, it boasts high power efficiency and no bulky heat sink is required..
【DSP Function】Automatic gain control (AGC), noise reduction (NR), voice trigger, voice trigger Xmit (VOX), RX attenuator attenuator (ATT), TX noise gate, TX driver control, volume control, dBm/S-meter..
【Quality Material Handling】Laser marking aluminum laser, aluminum knobs with translucent silicone buttons..

The HT201 has been designed to allow fuel injector and primary ignition waveforms to be measured using Hantek oscilloscope products..
Please note this attenuator should not be used for any high voltage measurements other than fuel injectors and primary ignition..
Passive attenuator with 20:1 attenuation, if input a 20V signal, it can output a 1V signal.Because the signal is attenuated, by using this item, oscilloscope can measure voltage higher than its range(±20V).
【What you will get】 1 x HT201 Signal Attenuation.
【Please Note】 After receiving the product, please check whether it is damaged. If you have any questions, please contact us in time. This product is a consumable and needs to be replaced regularly. Once the product is used, the warranty is not allowed..
