The t-meter family provides the only hand-held solution for easily making measurements of forward power, reflected power and VSWR.  Having a t-meter allows for quick and effective troubleshooting and verification of newly installed system-level hardware.

Without in-line attenuation, each meter will directly measure RF signals from 0dBm to +20dBm. With a 10dB inline attenuator, readings are scaled up to a range of +10dBm to +30dBm. With a 20dB attenuator, readings are scaled from +20dbm to +40dBm. With a 30dB attenuator, readings are scaled from +30dbm to +50dBm.

The Meter captures peak power over a 200mSec window so that it is ideal to measure peak power of 802.11 CDMA packetized communications. The peak detection circuit will capture a transmission as short as 500 microseconds and hold the measurement for one second.

Tactile switches are integral to the main electronics board and sealed from the elements by a weather-resistant overlay.

Datasheets for all models are listed in the right-hand column.
