TM 11-6625-3060-10
Operating Procedures
Measurement of rf voltage above 600 MHz.
1.
For measurements at frequencies above 600 MHz the RF PROBE must be used with a type N T ADAPTER, a
50-ohm termination and a fabricated coaxial cable for connection to the signal to be measured. Refer this
requirement to your organizational maintenance facility.
2.
Type N T Adapter Correction Curve is shown below. (Input voltage to T Adapter is indicated by voltmeter.)
Subtract the correction from the indicated value, in dB, to obtain output voltage of T Adapter.
3.
Typical VSWR of the RF PROBE with a type N T Adapter and 50-ohm termination is shown below.
