Descrizione del prodotto

The Bird 4381 is a digital RF wattmeter for two-way communications, avionics, C³, radar and many other applications. At the push of a button, this new wattmeter can perform the following functions:

Read incident and reflected CW and FM power in watts or dBm
Read incident and reflected peak-envelope-power of SSB/DSB and symmetrical AM in watts
Read incident and reflected peak pulse power as narrow as 50 micro-seconds in watts
Calculate SWR, dB return loss, percent modulation
Remember peak and valley readings when adjustments for maximum or minimum signal levels are made
Over-range at least 20 percent beyond nominal full scale
