TX Tests
• Frequency
• Power
• CTCSS
• Microphone sensitivity
• Modulation limiting
• Audio distortion
• Audio frequency response
• FM hum and noise
RX Tests
• Audio distortion
• Audio sensitivity
• Audio frequency response
• Usable sensitivity
• Displacement bandwidth
• Audio squelch sensitivity
• Audio squelch blocking
• Hum and noise
Test High/Low or both power level settings on any channel with
support for a PTT line to auto-key/de-key the transmitter. Single
channel test execution is allowed to re-check failed channels.
Supports re-test, accept failure or abort on any failed test. Supports
store and recall for test configurations and test results. Network or
local printer support allows for an immediate hard copy to be
obtained.
