The ScopeMatch antenna tuning aid is used to monitor the voltage and current at the output of the Power Amp. When the voltage and current sine waves are equal in amplitude and are in phase the antenna is properly tuned and maximum power will be radiated.

You can also use the scopematch to calculate the TPO (transmitter power out) One volt peak to peak from the scopematch equals 50 volts p-p. Formula is P=(vpp) squared /400 this assumes you have a 50 ohm load.

Example : If your O-Scope reads 4.0 volts peak to peak, multiply 4X50 = 200 and 200 squared is 40,000/400 = 100 watts.

I dedicate a 10 mhz 2 channel Pico 2204A USB computer O-Scope to the scopematch and it is displayed on a 7 in monitor. This allows me to monitor the antenna match at all times.
