LTRR Trunked Radio and Repeater Test Option Now Available
Option 18 provides the radio test professional with a cost effective solution for testing LTR repeaters and radios. Designed to provide LTR signaling and parametric analysis, this option provides the user with a simple interface found in other trunked test options for these service monitors, such as EDACS and MPT-1327.

When enabled with this option, the 2945B and 2948B provide complete analysis of the radio parameters including transmitter power, frequency error and modulation accuracy as well as receiver parameters including distortion and SINAD sensitivity measurements. Setting up LTR signaling on these service monitors is easy and provides the user with a quick means of verifying radio programming and operation before being released for use on a live system.

The 2948B Communications Service Monitor is the lightest, most rugged service monitor available with low phase-noise signal generation. For field work, the 2948B provides an excellent combination of instruments for all types of maintenance work. In the workshop it provides all of the performance you would expect for exacting measurements.
