** This is the first batch of VTx testing. Like or Dislike and let me know your comments below, in order to improve/modify/enrich this series now that it is in its early stages. ** ? Also let me know which FPV AiO combos or VTx boards you would like to see tested! ? ** Attention: As always, make sure you use frequencies that comply to your country's legislations. ** This is RCTESTBEN.CH: Eachine VTX03 FPV VTX RF Power Testing (25-50-200mW 72CH FPV micro VTX) - Let's go! The product: Brand: Eachine Model: VTX03 Type: micro VTx For pricing and availability you can check the link below: https://goo.gl/C6mvrW The test rig: The RCTestBen.ch test rig for VTx RF Power Output is a DIY setup. The RF Power Meter is made by ExpertRC and you can find it here: https://goo.gl/lfhgqd (Ebay) (the RF Power Meter is produced in small batches - check back if it is currently not available) Another similar device seems to be this one: https://goo.gl/wKmGua (Banggood) The case is 3D printed, you can find the design here: https://goo.gl/34pk3M (Thingiverse) Just to be clear: These tests are far from scientific BUT the main goal here is consistency and repeatability, so that you can compare the results between all the hardware tested. These tests focus in the transmitted power per channel/band. Channels, Bands and Frequencies are displayed according to manufacturer's spec sheets. The measuring equipment used has been tried and tested repeatedly before starting out this RCTestBen.ch series. The hardware that is tested is brand new and unused, in stock condition. Only 1 unit is tested and presented in this video. To my knowledge, this is not a cherry-picked product and certainly not a "best-of" measurements video. This is how the product performed right out of the box. The tested hardware (FPV AiO / VTx) is powered from a regulated DC source. You can watch the voltage and current draw throughout the test. The most prominent min and max values are logged on each channel of each band / power output. If you see a different value on the RF Power Meter in a still capture, it just happened to show up briefly when the photo was taken. Same applies for power consumption. It is monitored throughout the whole duration of the test and the most prominent min and max values on each channel are logged. The FPV AiO camera/VTx combos are tested by de-soldering the stock antenna and soldering a coax cable in its place, which is connected on the other side to the RF Power Meter. There are plenty of the exact same conductor with the exact same length from the same batch, as spares. VTx boards with u.FL (IPEX) connector are tested via a u.FL to SMA thin coaxial cable. VTx boards with SMA or RP-SMA connector are tested via an SMA to SMA cable plus an adapter for RP-SMA. All these cables and adapters are available as spares (the exact same types, from the same batch). Cooling plays a huge factor in the RF power output of VTx boards. Leaving a VTx running for a short period of time in room temperature results in a quick drop of power output - even by blowing with your mouth results in a quick rise in power output. All FPV AiO and VTx boards are tested with a constant airflow over both sides of the VTx PCB board. Testing is done slowly and may take up to 35 minutes, depending on the amount of bands/channels available on the tested VTx board - after all the channels are cycled through, settled, measured and logged, the first channels are re-checked in order to confirm accuracy, consistency and stability of the transmitted power. 👍 PLEASE SUPPORT the MuteFPV channel: ------- 👍 Join my PATREON: http://mutefpv.com/patreon 👍 Tip my 'piggy bank' via PAYPAL: http://mutefpv.com/paypal 👍 Save and use these BOOKMARKS before purchasing new goodies (please bookmark the SHORTLINKS in your browser): BANGGOOD: http://mutefpv.com/banggood AMAZON (paid link): http://mutefpv.com/amazon GETFPV: http://mutefpv.com/getfpv EBAY: http://mutefpv.com/ebay ALIEXPRESS: http://mutefpv.com/aliexpress REELSTEADY: http://mutefpv.com/reelsteady 👍 THANK YOU in advance for your support!
