Technisonics Type 1 Radio Auto-Test/Alignment
(390XOPT614)
This option adds the capability to complete a fully automatic test and
alignment on Technisonics Type 1 radios. This option provides the
same functionality of the ASTRO Series radio Auto-Test/alignment
software, but for the Technisonics Type 1 radios.
Technisonics Type 2 Radio Auto-Test/Alignment
(390XOPT615)
This option adds the capability to complete a fully automatic test and
alignment on Technisonics Type 2 radios. This option provides the
same functionality of the ASTRO 25 Series radio Auto-Test/align-
ment software, but for the Technisonics Type 2 radios.
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.
DMR Repeater Auto-Test (390XOPT626)
With the DMR repeater auto-test, the 3920B can automatically
perform the key transmitter and receiver tests for DMR Repeaters.
This test does not require the DMR repeater to be in any special test
mode, but can quickly make these measurements on any channel pro-
grammed into the repeater. The user simply indicates the frequencies
that the repeater is using from the auto-test setup screen, and then
can initiate the test and walk away. The testing is all performed com-
pletely automatically
