Page 4: Introduction To The T-Meter
T-METER Introduction to the t-meter The t-meter is a handheld broadband power meter capable of detect- ing forward and reflected power in a microwave radio system. The meter is capable of detecting various types of wireless broadband modulation schemes in the license exempt 2.4, 5.3, and 5.8GHz fre- quency bands, with application specific coverage at 4.9GHz (PM-... -
Page 5: Using The T-Meter
P R A X S Y M Using the t-meter The t-meter ships with a durable nylon case that is secured with hook and loop flaps. The package is designed such that the meter can be used while still in the nylon case. The flaps that cover and protect the meter can be secured behind the unit while it is in use. - Page 6 T-METER The meter should always be inserted into the system in the forward power direction. Use the arrow labeled “FORWARD SIGNAL” as a guide when connecting the meter. Pressing and quickly releasing the ON-OFF button turns the meter on. The meter will display “Below Range” if it is not connected to a source that is within it’s dynamic range (0 to 20dBm).
- Page 7 P R A X S Y M measurement is displayed continuously. The VSWR is displayed for two seconds on the bottom display line and then is replaced for one second by the band indi- cator (“2.4G” for example) and the in-line attenu- ator setting (“+00,”...

T-METER Measuring VSWR of Antenna and Termina- tions To measure the VSWR of an antenna, place the meter into the system between the transmission line and the antenna. Use the “FORWARD SIGNAL” arrow on the meter to orient the meter properly. The arrow will point towards the antenna when it is properly inserted. - Page 13 P R A X S Y M Page 10...
